Modern man is intelligent. Homo sapiens Homo sapiens
Remark 1
Homo sapiens (lat. Homo sapiens) is the systematic name used in taxonomy (also known as binomial nomenclature) for anatomically modern humans, that is, the only surviving human species. This name was introduced in 1758 by Carl Linnaeus (who himself is also a type specimen).
Speciation
Extinct species of the genus Homo are classified as "archaic humans". This genus includes at least a single species of Homo erectus and possibly a number of other species (which are variously considered to be also subspecies of either H. sapiens or H. erectus. H. sapiens idaltu is a proposed extinct subspecies of H. sapiens.
The age of speciation of H. sapiens from ancestral H. erectus (or intermediate species such as Homo heidelbergensis) is thought to be between about 300,000-200,000 years ago. However, intermingling with archaic human species is believed to have continued over a period of time until about 30,000 years ago, the point of extinction for any surviving archaic human species that appears to have been absorbed into the expansion of Homo sapiens beginning about 50,000 years ago.
Genus Homo
Definition 1
Homo is a genus that covers the extant species of Homo sapiens (modern humans) as well as several extinct species classified as its ancestors or closely related to modern humans.
The genus Homo is 2 to 3 million years old and is descended from the genus Australopithecus, which itself had previously split from the line of Pan, the chimpanzee. Taxonomically, Homo is the only genus assigned to the subtribes Hominina, which, with the subtropics Australopithecina and Panina, constitute the tribe Hominini. All species of the genus Homo, together with the species of Australopithecus that arose after the split from Pan, are called hominins. Species of the genus Homo:
- Homo habilis (Handy man) 2.6-2.5 (million years ago) Range: Africa
- Homo rudolfensis (Rudolf Man) 2-1.78 (million years ago) Range: Kenya
- Homo erectus (Human erectus) 2-0.03 (million years ago) Range: Africa, Eurasia (Java, China, Caucasus)
- Homo georgicus (Georgian Man) 1.8 (million years ago) Range: Georgia
- Homo ergaster (Man working) 1.8-1.4 (million years ago) Range: South and East Africa
- Homo antecessor (Man-predecessor) 1.2-0.8 (million years ago) Range: Spain
- Homo cepranensis (Man from Ceprano) 0.9-0.8 (million years ago) Range: Italy
- Homo heidelbergensis (Heidelberg man) 0.8-0.345 (million years ago) Range: Europe, Africa, China
- Homo rhodesiensis (Rhodesian man) 0.3-0.12 (million years ago) Range: Zambia
- Homo neanderthalensis (Neanderthal) 0.35-0.040 (million years ago) Range: Europe, Western Asia
- Homo sapiens sapiens (Homo sapiens) 0.2-B.C. V. Range: all over
- Homo sapiens idaltu (Old Homo sapiens) 0.16-0.15 (million years ago) Range: Ethiopia
- Homo floresiensis (Floresian man) 0.10-0.012 (million years ago) Range: Indonesia
Homo erectus and Homo sapiens sapiens are among the most important species of the genus Homo.
Homo erectus - appeared about two million years ago in East Africa(where it was named Homo ergaster), and in several early migrations it spread throughout Africa and Eurasia. Probably the first hominin lived in a hunter-gatherer society and controlled the fire.
The adaptive and successful Homo erectus species persisted for almost 2 million years before suddenly becoming extinct around 70,000 years ago (0.07 million years), possibly victims of the ultrafast Toba catastrophe.
Homo sapiens sapiens - anatomically comparable to modern humans, appeared about 200,000 years ago (0.2 million years ago) in East Africa Modern humans migrated out of Africa as early as 60,000 years ago. During the Upper Paleolithic, they spread throughout Africa, Eurasia, Oceania, and America, and they encountered archaic people along the way during these migrations. Homo sapiens sapiens is the only surviving species and subspecies of the genus Homo.
Origin of Homo sapiens
Remark 2
Traditionally in paleoanthropology, there are two competing views on the origin of H. sapiens: a recent African origin and a multiregional origin.
Recent genetic studies have also resulted in an intermediate position, characterized mainly by recent African ancestry with the addition of limited admixture (introgression) from archaic humans.
The recent African origin of modern humans is the main model that describes the origin and early distribution of anatomically modern humans. The theory is called the (recent) Out-of-Africa model, and also the Academically Recent Single Origin Hypothesis (RSOH), instead of the Recent African Origin Hypothesis and Model (RAO). The hypothesis that humans have a single origin (monogenesis) was published in The Descent of Man by Charles Darwin (1871). This concept was speculative until the 1980s, when it was confirmed by the study of modern mitochondrial DNA, combined with evidence based on the physical anthropology of archaic specimens. According to genetic and fossil evidence, archaic Homo sapiens evolved to anatomically modern humans in Africa approximately 200,000 years ago, at the time when members of one branch of the species left Africa 60,000 years ago and eventually replaced earlier human populations such as Neanderthals and Homo erectus. A very recent (2017) study of fossils found in Jebel Irud (Morocco) suggests that Homo sapiens may have evolved as early as 315,000 years ago. Some other evidence also suggests that Homo sapiens may have migrated out of Africa as early as 270,000 years ago.
Remark 3
The recent single origin of modern humans in East Africa was a near-consensual position held in the scientific community until 2010. However, in 2010 significant archaic human admixture with modern humans was found.
The multi-regional origin model proposed by Milford H. Wolpoff in 1988 provides a different explanation for the pattern of human evolution. The multi-regional origin suggests that the evolution of mankind dates back to the Pleistocene of 2.5 million years and has been one continuous human species up to the present.
In the light of already published and future videos, for the general development and systematization of knowledge, I propose a generalized review of the genera of the hominid family from the later Sahelanthropes, who lived about 7 million years ago, to Homo sapiens, which appeared from 315 to 200 thousand years ago. This review will help not to fall into the trap of those who like to mislead and systematize their knowledge. Since the video is quite long, for convenience, in the comments there will be a table of contents with a time code, thanks to which you can start or continue watching the video, from the selected genus or species, if you click on the numbers of blue color in the list. 1. Sahelanthropus This genus is represented by only one species: 1.1. The Chadian Sahelanthropus (Sahelanthropus tchadensis) is an extinct species of hominin, about 7 million years old. His skull, named Tumaina, which means "hope for life", was found in the northwest of the Republic of Chad in 2001 by Michel Brunet. The volume of their brain, presumably 380 cubic cm, is approximately the same as that of modern chimpanzees. According to the characteristic location of the occipital foramen, scientists believe that this is the most ancient skull of an upright creature. Sahelanthropus may represent a common ancestor of humans and chimpanzees, but there are still a number of questions about his facial features that may cast doubt on the status of Australopithecus. By the way, the affiliation of sahelanthropes to the human pedigree is disputed by the discoverers of the next genus with the only species Ororin tugensis. 2. Genus Orrorin (Orrorin) includes one species: Orrorin tugensis (Orrorin tugenensis), or man of the millennium, this species was first found in 2000 in the Tugen mountains of Kenya. Its age is about 6 million years. Currently, 20 fossils have been found at 4 sites: these include two parts of the lower jaw; symphyses and several teeth; three fragments of a thigh; partial humerus; proximal phalanx; and the distal phalanx of the thumb. By the way, in Orrorins, the femurs with obvious signs of upright posture, in contrast to the indirect ones in Sahelanthropes. But the rest of the skeleton, except for the skull, indicates that he climbed trees. Orrorins were about 1m tall. 20 centimeters. In addition, related finds indicated that Orrorin did not live in the savannah, but in an evergreen forest environment. By the way, it is this species that is demonstrated by lovers of sensations in anthropology or supporters of ideas about the extraterrestrial origin of people, saying that 6 million years ago aliens visited us. As evidence, they note that this species has a femur closer to a human than that of a later species of Afar Australopithecus, named Lucy, 3 million years old, this is true, but understandable, which scientists did 5 years ago, describing the level of primitiveness of similarity and that it is similar to primates that lived 20 million years ago. But on top of that argument, the TV experts report that Orrorin's reconstructed face is flat and human-like. And then take a close look at the images of the finds and find the parts from which you can assemble the face. Don't you see? Me too, but they are there, according to the authors of the programs! At the same time, fragments of a video about completely different finds are shown. This is calculated on the fact that they are trusted by hundreds of thousands, or even millions of viewers, and they will not check. This is how, mixing truth and fiction, a sensation is obtained, but only in the minds of their adherents, and, unfortunately, there are not a few of them. And this is just one example. 3. Ardipithecus (Ardipithecus), an ancient genus of hominids that lived 5.6-4.4 million years ago. At the moment, only two species are described: 3.1. Ardipithecus kadabba (Ardipithecus kadabba) was found in Ethiopia in the valley of the Middle Awash River in 1997. And in 2000, to the north, a few more finds were found. The finds are represented mainly by teeth and fragments of skeletal bones, from several individuals, 5.6 million years old. The following species from the genus Ardipithecus is more qualitatively described. 3.2. Ardipithecus ramidus (Ardipithecus ramidus) or Ardi, which means earth or root. The remains of Ardi were first discovered near the Ethiopian village of Aramis in 1992 in the Afar depression in the Awash River valley. And in 1994, more fragments were obtained, which accounted for 45% of the total skeleton. This is a very significant find, which combines the features of both monkeys and humans. The age of the finds was determined based on their stratigraphic position between two volcanic layers and amounted to 4.4 Ma. And between 1999 and 2003, scientists discovered the bones and teeth of nine more individuals of the Ardipithecus ramidus species, on the northern bank of the Awash River in Ethiopia, west of Hadar. Ardipithecus is similar to most of the primitive previously recognized hominins, but unlike them, Ardipithecus ramidus had a big toe that retained grasping ability, adapted for climbing trees. However, scientists argue that other features of its skeleton reflect an adaptation to upright posture. Like late hominins, Ardi had reduced fangs. Its brain was about the size of a modern chimpanzee and about 20% the size of a modern human brain. Their teeth say that they ate both fruits and leaves without preference, and this is already the path to omnivorousness. In terms of social behavior, slight sexual dimorphism may indicate a decrease in aggression and competition between males in a group. The legs of the ramidus are well suited for walking both in the forest and in the conditions of meadows, swamps and lakes. 4. Australopithecus (Australopithecus), here it should immediately be noted that there is also the concept of Australopithecus, which includes 5 more genera and is divided into 3 groups: a) early Australopithecus (7.0 - 3.9 million years ago). years ago); b) gracile australopithecines (3.9 - 1.8 million years ago); c) massive australopithecines (2.6 - 0.9 million years ago). But Australopithecus as a genus is a fossil higher primate with signs of upright walking and anthropoid features in the structure of the skull. Who lived in the period from 4.2 to 1.8 million years ago. Let's consider 6 types of Australopithecus: 4.1. The Australopithecus anamensis of Anamen is believed to be the ancestor of humans, who lived about four million years ago. Fossils have been found in Kenya and Ethiopia. The first find of the species was discovered in 1965 near Lake Turkana in Kenya, previously the lake was called Rudolf. Then, in 1989, teeth of this species were found on the northern coast of Turkana, but on the territory of modern Ethiopia. And already in 1994, about a hundred additional fragments from two dozen hominids were discovered, including one complete lower jaw, with teeth resembling human ones. And only in 1995, on the basis of the described finds, the species was identified as Anamsky Australopithecus, which is considered a descendant of the species Ardipithecus ramidus. And in 2006, a new find of the Anaman Australopithecus was announced, in northeastern Ethiopia, about 10 km. from the site of the finds of Ardipithecus ramidus. The age of the Anamese australopithecines is about 4-4.5 million years. Anamsky Australopithecus is considered the ancestor of the following species of Australopithecus. 4.2. The Afar Australopithecus (Australopithecus afarensis), or "Lucy", after the first find, is an extinct hominid that lived between 3.9 and 2.9 million years ago. The Afar Australopithecus was closely related to the genus Homo, either as a direct ancestor or close relative of an unknown common ancestor. Lucy herself, 3.2 million years old, was discovered in 1974 in the Afar Basin near the village of Hadar in Ethiopia on November 24. "Lucy" was represented by an almost complete skeleton. And the name "Lucy" was inspired by the Beatles song "Lucy in the sky with diamonds." Afar australopithecines have also been found in other localities such as Omo, Maka, Feige and Belohdeli in Ethiopia and Koobi Fore and Lotagam in Kenya. Representatives of the species had fangs and molars relatively larger than those of modern humans, and the brain was still small - from 380 to 430 cubic cm - the face was with protruding lips. The anatomy of the arms, legs, and shoulder joints suggests that the creatures were partially arboreal and not only terrestrial, although in general anatomy the pelvis is much more human-like. However, due to the anatomical structure, they could already walk with an upright gait. The upright posture of the Afar Australopithecus may just be due to climate change in Africa from the jungle to the savannah. In Tanzania, 20 km from the Sadiman volcano, in 1978 footprints of a family of upright hominids were discovered, preserved in volcanic ash south of Olduvai Gorge. Based on sexual dimorphism - the difference in body size between males and females - these creatures most likely lived in small family groups containing one dominant and larger male and several small breeding females. "Lucy" would live in a group culture that involves communication. In 2000, a skeletal remains of what is believed to be a 3-year-old child of Afar australopithecines, who lived 3.3 million years ago, were discovered in the Dikik region. These Australopithecus, according to archaeological finds, used stone tools for cutting meat from animal carcasses and crushing. But this is only the use, not the manufacture of them. 4.3. The Bahr el Ghazal Australopithecus (Australopithecus bahrelghazali) or Abel is a fossil hominin first discovered in 1993 in the Bahr el Ghazal Valley at the Koro Toro archaeological site in Chad. Abel is approximately 3.6-3 million years old. The find consists of a mandibular fragment, the lower second incisor, both the lower canines and all four of its premolars. This australopithecine fell into a separate species thanks to its lower three root premolars. It is also the first australopithecine discovered north of the previous ones, which indicates their wide distribution. 4.4 The African Australopithecus (Australopithecus africanus) was an early hominid that lived 3.3 to 2.1 million years ago during the late Pliocene and early Pleistocene. Unlike the previous species, it had a larger brain and more human-like features. Many scientists believe that he is the ancestor of modern humans. The African Australopithecus has only been found at four sites in southern Africa - Taung in 1924, Sterkfontein in 1935, Makapansgat in 1948 and Gladysvale in 1992. The first find was a baby skull known as the "Taung Baby" and described by Raymond Dart, who named it Australopithecus africanus, meaning "southern monkey of Africa". He claimed that this species was intermediate between apes and humans. Further discoveries confirmed their separation into a new species. This australopithecine was a bipedal hominid with arms slightly longer than legs. Despite its somewhat more human-like cranial features, other more primitive features are present, including simian-like, curved climbing fingers. But the pelvis was more adapted to bipedalism than in the previous species. 4.5. Australopithecus garhi (Australopithecus garhi), 2.5 million years old, was discovered in Ethiopia in the Bowri deposits. "Garhi" means "surprise" in the local Afar language. For the first time, tools similar to the Aldovan culture of stone processing were found along with the remains. 4.6. Australopithecus sediba (Australopithecus sediba) is a species of australopithecines of the early Pleistocene, represented by fossils dating back to about 2 million years. This species is known from four incomplete skeletons found in South Africa in a place called the "cradle of mankind", 50 km northwest of Johannesburg, within the Malapa cave. The discovery was made thanks to the Google Earth service. "Sediba" means "spring" in the Sotho language. Australopithecus sediba, two adults, and one 18-month-old infant were found together. In total, more than 220 fragments have been excavated so far. Australopithecus sediba may have lived in the savannah, but the diet included fruits and other forest products. The height of the sediba was about 1.3 meters. The first specimen of Australopithecus sediba was discovered by 9-year-old Matthew, son of paleoanthropologist Lee Berger, on August 15, 2008. The mandible found was part of a young male whose skull was discovered later in March 2009 by Berger and his team. Also in the area of the cave were found fossils of various animals, including saber-toothed cats, mongooses and antelopes. The volume of the brain of a sediba was about 420-450 cubic cm, which is about three times less than that of modern people. Australopithecus sediba had amazing modern hand , whose grip accuracy involves the use and manufacture of the tool. Sediba probably belonged to a late South African branch of Australopithecus, which coexisted with members of the genus Homo already living at that time. Currently, some scientists are trying to clarify the dates and look for a connection between Australopithecus sediba and the genus Homo. 5. Paranthropus (Paranthropus) - a genus of fossil higher primates. They have been found in East and South Africa. They are also called massive australopithecines. Paranthropus finds are dated from 2.7 to 1 million years ago. 5.1. Ethiopian Paranthropus (Paranthropus aethiopicus or Australopithecus aethiopicus) The species was described from a 1985 find in the Turkana Lake area, Kenya, known as the "black skull" due to its dark color due to its manganese content. The skull has been dated to 2.5 million years. But later, part of the lower jaw, discovered in 1967 in the Omo River Valley, Ethiopia, was also attributed to this species. Anthropologists believe that the Ethiopian Paranthropus lived between 2.7 and 2.5 million years ago. They were quite primitive and share many features with the Afar Australopithecus, possibly being their direct descendants. Their special feature was strongly protruding jaws. This species is believed to diverge from the Homo lineage on the evolutionary branch of the hominid tree. 5.2. Boise's Paranthropus (Paranthropus boisei) aka Australopithecus boisei, aka "The Nutcracker" was an early hominin described as the largest of the Paranthropus genus. They lived in East Africa during the Pleistocene era from about 2.4 to 1.4 million years ago. The largest skull found at Konso in Ethiopia dates back to 1.4 million years. They were 1.2-1.5 m tall, and weighed from 40 to 90 kg. The well-preserved skull of the paranthropus bois was first discovered in Olduvai Gorge in Tanzania in 1959 and was given the name Nutcracker, due to its large teeth and thick enamel. It has been dated at 1.75 million. And 10 years later, in 1969, the son of the discoverer of the "Nutcracker" Mary Leakey Richard discovered another skull of paranthropus boyes in Koobi Fora near Lake Turkana in Kenya. Judging by the structure of the jaws, they ate massive plant foods, and lived in forests and shrouds. According to the structure of the skull, scientists believe that the brain of these Paranthropus was quite primitive, up to 550 cubic cm in volume. 5.3. Paranthropus massive (Paranthropus robustus). The first skull of this species was discovered at Kromdraai in South Africa in 1938 by a schoolboy who later traded it for chocolate to anthropologist Robert Broom. Paranthropus or Massive Australopithecus were bipedal hominids that probably evolved from graceful australopithecines. They are characterized by strong skullcaps, and gorilla-like cranial ridges that suggest strong chewing muscles. They lived between 2 and 1.2 million years ago. The remains of massive paranthropes have been found only within South Africa at Kromdraai, Swartkrans, Drimolen, Gondolin and Coopers. The remains of 130 individuals were found in a cave in Swartkrans. Dental studies have shown that massive paranthropes rarely lived to 17 years of age. The approximate height of the males was about 1.2 m, and their weight was about 54 kg. But the females were a little less than 1 meter tall and weighed about 40 kg, which indicates a rather large sexual dimorphism. Their brain size ranged from 410 to 530 cc. see. They ate rather massive food, such as tubers and nuts, possibly from open forests and savannahs. 6. Kenyanthropus (Kenyanthropus) a genus of hominids who lived from 3.5 to 3.2 million years ago in the Pliocene. This genus is represented by one species, Kenyanthropus flatface, but some scientists consider it a separate species of Australopithecus, like Australopithecus flatface, while others attribute it to Afar Australopithecus. 6.1. The flat-faced Kenyanthropus (Kenyanthropus platyops) was found on the Kenyan side of Lake Turkana in 1999. These Kenyanthropes lived from 3.5 to 3.2 million years ago. This species remains a mystery, and suggests that 3.5 - 2 million years ago there were several humanoid species, each of which was well adapted to life in a certain environment. 7. The genus People or Homo includes both extinct species and Homo sapiens. Extinct species classified as ancestral, especially Homo erectus, or as closely related to modern humans. The earliest representatives of the genus, at the moment, date back to 2.5 million years. 7.1. Homo gautengensis is a species of hominin that was isolated in 2010 after taking a fresh look at a skull found back in 1977 in Sterkfontein Cave in Johannesburg, South Africa, Gotheng. This species is represented by South African fossil hominins, formerly referred to as Handy Man (Homo habilis), Working Man (Homo ergaster), or in some cases Australopithecus. But Australopithecus sediba, who lived at the same time as Homo Gautengensis, turned out to be much more primitive. Homo gautengensis has been identified from skull fragments, teeth, and other parts found at various times in caves at a site called the Cradle of Humankind in South Africa. The oldest specimens are dated at 1.9-1.8 million years. The youngest specimens from Swartkrans date from about 1.0 million to 600 thousand years. According to the description, Homo Gautengensis had large teeth suitable for chewing plants and a small brain, most likely he consumed a predominantly plant food, in contrast to Homo erectus, Homo sapiens and, probably, Homo habilis. According to scientists, he produced and used stone tools, and judging by the burnt animal bones found with the remains of Homo Gautengensis, these hominins used fire. They were a little over 90 cm tall, and their weight was about 50 kg. Homo Gautengensis walked on two legs, but also spent considerable time in the trees, possibly feeding, sleeping, and sheltering from predators. 7.2. Rudolf man (Homo rudolfensis), a species of the genus Homo, who lived 1.7-2.5 million years ago, was first discovered in 1972 on Lake Turkana in Kenya. However, the remains were first described in 1978 by the Soviet anthropologist Valery Alekseev. Remains have also been found in Malawi in 1991 and in Koobi-fora, Kenya in 2012. Rudolf man coexisted in parallel with Homo habilis or skillful man and they could interact. Possibly ancestral to later Homo species. 7.3. Handyman (Homo habilis) is a species of fossil hominin that is considered to be representative of our ancestors. Lived from about 2.4 to 1.4 million years ago, during the Gelazian Pleistocene. The first finds were discovered in Tanzania in 1962-1964. Homo habilis was thought to be the earliest known species of the genus Homo, until the discovery of Homo Gautengensis in 2010. Homo habilis was short and had disproportionately long arms compared to modern humans, but with a flatter face than Australopithecus. The volume of his skull was less than half compared to modern humans. His finds are often accompanied by primitive stone tools from the Olduvai culture, hence the name "Handyman". And if it is easier to describe, then the body of the habilis resembles Australopithecus, with a more human-like face and smaller teeth. Whether Homo habilis was the first hominid to possess stone tool technology remains debatable, as Australopithecus garhi dated 2. 6 million years old, was found along with similar stone tools, and it is at least 100-200 thousand years older than Homo habilis. Homo habilis lived in parallel with other bipedal primates such as Paranthropus boisei. But Homo habilis, perhaps through the use of a tool and a more varied diet, appears to have been the forerunner of a whole line of new species by dental analysis, while the remains of Paranthropus boisei have not been found again. It is also possible that Homo habilis coexisted with Homo erectus around 500,000 years ago. 7.4. Homo ergaster is an extinct but one of the earliest species of Homo that lived in eastern and southern Africa during the early Pleistocene, 1.8 - 1.3 million years ago. Man working, named for his advanced technology hand tools , it is sometimes referred to as the African Homo erectus. Some researchers consider the working man to be the ancestor of the Acheulian culture, while other scientists give the palm to the early erectus. There is also evidence of their use of fire. The remains were first discovered in 1949 in southern Africa. And the most complete skeleton was found in Kenya on the western shore of Lake Turkana, it belonged to a teenager and was called "The Boy from Turkana" or also "Nariokotome Boy", his age was 1.6 million years. Often this find is classified as Homo erectus. Homo ergaster is believed to have diverged from the Homo habilis lineage between 1.9 and 1.8 million years ago and existed for about half a million years in Africa. Scientists also believe that they quickly became sexually mature, even in their youth. Its distinguishing feature was also rather tall, about 180 cm. The worker also has less sexual dimorphism than Austropithecus, and this may mean more prosocial behavior. His brain was already larger, up to 900 cubic centimeters. Some scientists believe that they could use a proto-language based on the structure of the cervical vertebrae, but this is only speculation at the moment. 7.5. The Dmanisian hominid (Homo georgicus) or (Homo erectus georgicus) is the first member of the Homo genus to leave Africa. The finds, dated at 1.8 million years, were discovered in Georgia in August 1991, described in different years also as Georgian Man (Homo georgicus), Homo erectus georgicus, Dmanisi hominid (Dmanisi) and as Working Man (Homo ergaster). But it was separated into a separate species and, together with erectus and ergaster, they are also often called archanthropes, or if we add here the Heidelberg man of Europe and Sinanthropus from China, we will already get Pithecanthropes. In 1991 by David Lordkipanidze. Along with ancient human remains, tools and animal bones were found. The brain volume of Dmanisian hominids is approximately 600-700 cubic centimeters - two times less than that of modern humans. This is the smallest hominid brain found outside of Africa, other than the Floresian man (Homo floresiensis). The Dmanisian hominid was bipedal and shorter than the abnormally tall ergaster, the average height of males was about 1.2m. Dental conditions indicate omnivory. But among the archaeological finds, evidence of the use of fire was not found. Possibly a descendant of Rudolf Man. 7.6. Homo erectus, or simply Erectus, is an extinct species of hominin that lived from the late Pliocene to the late Pleistocene, approximately 1.9 million to 300,000 years ago. About 2 million years ago, the climate in Africa just changed to drier. long time existence and migration could not but create many different views of scientists on this species. According to the available data and their interpretation, the species originated in Africa, then migrated to India, China and to the island of Java. In general, Homo erectus settled in the warm parts of Eurasia. But some scientists suggest that erectus appeared in Asia and only then migrated to Africa. Erectus have existed for over a million years, longer than other human species. The classification and lineage of Homo erectus is quite controversial. But there are some subspecies of erectus. 7.6.1 Pithecanthropus or "Javanese Man" - Homo erectus erectus 7.6.2 Yuanmou Man - Homo erectus yuanmouensis 7.6.3 Lantian Man - Homo erectus lantianensis 7.6.4 Nanjing Man - Homo erectus nankinensis 7.6.5 Sinanthropus or "Beijing Man" - Homo erectus pekinensis 7.6.6 Meganthrope - Homo erectus palaeojavanicus 7.6.7 Javanthrope or Soloyan man - Homo erectus soloensis 7.6.8 Man from Totavel - Homo erectus tautavelensis 7.6.9 Dmanisian hominid - Homo erectus georgicus 7.6.10 Man from Bilzingsleben - Homo erectus bilzingslebenensis 7.6.11 Atlantrope or Moorish man - Homo erectus mauritanicus 7.6.12 Cherpano man - Homo cepranensis, some scientists distinguish it, like many other subspecies, into a separate species, but the 1994 find in the vicinity of Rome is represented only by a skull, therefore little data for a more thorough analysis. Homo erectus got its name for a reason, its legs were adapted for both walking and running. Temperature metabolism was increased by thinner and shorter body hair. It is possible that erectus have already become hunters. Smaller teeth may indicate a change in diet, most likely due to fire treatment. And this is already a way to increase the brain, the volume of which in erectus varied from 850 to 1200 cubic cm. They were up to 178 cm tall. Erectus sexual dimorphism was less than that of its predecessors. They lived in hunter-gatherer groups and hunted together. They used fire both for warmth and cooking, and to scare away predators. They made tools, hand axes, flakes, and in general were carriers of the Acheulean culture. In 1998, there were suggestions that they were building rafts. 7.7. Homo antecessor is an extinct human species, between 1.2 million and 800,000 years old. Found in the Sierra de Atapuerca in 1994. The fossil of the upper jaw and part of the skull, 900 thousand years old, discovered in Spain, belonged to a boy of a maximum of 15 years. Many bones, both animal and human, were found nearby, bearing marks that could indicate cannibalism. Nearly all of those eaten were teenagers or children. At the same time, there was no evidence indicating a lack of food in the vicinity at that time. They were about 160-180 cm tall and weighed about 90 kg. The volume of the human brain of the previous (Homo antecessor) was about 1000-1150 cubic centimeters. Scientists suggest a rudimentary ability to speak. 7.8. Heidelberg man (Homo heidelbergensis) or protanthropus (Protanthropus heidelbergensis) is an extinct species of the genus Homo, which may be the direct ancestor of both Neanderthals (Homo neanderthalensis), if we consider its development in Europe, and Homo sapiens, but only in Africa. The discovered remains were dated from 800 to 150 thousand years. The first records of this species were made in 1907 by Daniel Hartmann in the village of Mauer in southwestern Germany. After that, representatives of the species were found in France, Italy, Spain, Greece and China. Also in 1994, a discovery was made in England near the village of Boxgrove, hence the name "Man from Boxgrove" (Boxgrove Man). However, the name of the area is also found - "horse slaughterhouse", which involves butchering horse carcasses using stone tools. Heidelberg man used the tools of the Acheulean culture, sometimes with transitions to the Mousterian culture. They were on average 170 cm tall, and in South Africa there were finds of individuals 213 cm tall and dated from 500 to 300 thousand years. The Heidelberg Man may have been first view , who buried his dead, these conclusions are based on 28 remains found in Atapuerca, Spain. He may have used tongue and red ocher as decoration, as evidenced by finds at Terra Amata near Nice on the slopes of Mount Boron. Dental analysis suggests they were right-handed. Heidelberg man (Homo heidelbergensis) was an advanced hunter, judging by hunting tools such as spears from Schöningen in Germany. 7.8.1. Rhodesian man (Homo rhodesiensis) is an extinct subspecies of hominins that lived from 400 to 125 thousand years ago. The Kabwe fossil skull is a typical specimen of this species, found in the Broken Hill Caves in Northern Rhodesia, now Zambia, by the Swiss miner Tom Zwieglaar in 1921. Previously, it stood out as a separate species. The Rhodesian man was massive, with very large eyebrows and a broad face. He is sometimes called the "African Neanderthal", although he has intermediate features between sapiens and Neanderthals. 7.9. Florisbad (Homo helmei) is described as an "archaic" Homo sapiens that lived 260,000 years ago. Represented by a partially preserved skull that was discovered in 1932 by Professor Dreyer within the archaeological and paleontological site of Florisbad near Bloemfontein in South Africa. It may be an intermediate form between Heidelberg man (Homo heidelbergensis) and Homo sapiens. Florisbad was the same size as a modern human, but with a large brain volume of about 1400 cubic cm. 7.10 The Neanderthal (Homo neanderthalensis) is an extinct species or subspecies within the genus Homo, closely related to, and interbred with, modern humans. The term "Neanderthal" comes from the modern spelling of the Neander Valley in Germany, where the species was first discovered in the Feldhofer Cave. Neanderthals existed, according to genetic data, from 600 thousand years ago, and according to archaeological finds from 250 to 28 thousand years ago, with the last refuge in Gibraltar. The finds are currently being intensively studied and it makes no sense to describe in more detail, since I will return to this species again and possibly more than once. 7.11. Homo Naledi Fossils were discovered in 2013 in Dinaledi Chamber, Rising Star Cave System, Gauteng Province in South Africa and were quickly recognized as the remains of a new species in 2015, and distinct from the remains found previously. In 2017, the finds are dated from 335 to 236 thousand years. The remains of fifteen individuals, both male and female, were recovered from the cave, among them were children. The new kind named Homo naledi, it has an unexpected combination of modern and primitive features, including a rather small brain. The growth of "Naledi" was about one and a half meters, the volume of the brain was from 450 to 610 cubic meters. See The word "ice" means "star" in the Sotho-Tswana languages. 7.12. Floresian man (Homo floresiensis) or Hobbit is an extinct dwarf species of the genus Homo. The Floresian man lived from 100 to 60 thousand years ago. Archaeological remains were discovered by Mike Morewood in 2003 on the island of Flores in Indonesia. Incomplete skeletons of nine individuals have been recovered, including one complete skull, from Liang Bua Cave. A distinctive feature of hobbits, as the name implies, is their height, about 1 meter and a small brain, about 400 cm3. Stone tools were found along with skeletal remains. There is still debate about the Floresian man, whether he could make tools with such a brain. The theory was put forward that the found skull is a microcephaly. But most likely this species evolved from erectus or other species in isolation on the island. 7.13. Denisovans (Denisova hominin) are Paleolithic members of the genus Homo that may belong to a previously unknown human species. It is believed to be the third person, from the Pleistocene, to have demonstrated a level of adaptation previously thought to be unique to modern humans and Neanderthals. Denisovans occupied large territories, stretching from cold Siberia to the tropical rainforests of Indonesia. In 2008, Russian scientists, in Denisova Cave or Ayu-Tash, in the Altai Mountains, a distal phalanx of a girl's finger was discovered, from which mitochondrial DNA was later isolated. The mistress of the phalanx lived in a cave about 41 thousand years ago. This cave was also inhabited by Neanderthals and modern humans in different time. In general, there are not many finds, including teeth and part of the phalanx of the toe, as well as various tools and jewelry, including a bracelet not made of local material. Bone mitochondrial DNA analysis thumbs up that Denisovans are genetically different from Neanderthals and modern humans. They may have split from the Neanderthal line after the split with the Homo sapiens line. Recent analyzes have also shown that they overlapped with our species, and even interbred multiple times, at different times. Up to 5-6% of the DNA of the Melanesians and Australian Aborigines contain Denisovan admixtures. And modern non-Africans have about 2-3% impurities. In 2017, in China, fragments of skulls were found, with a large brain volume, up to 1800 cubic cm and an age of 105-125 thousand years. Some scientists based on their description suggested that they could belong to the Denisovans, but these versions are currently controversial. 7.14. Idaltu (Homo sapiens idaltu) is an extinct subspecies of Homo sapiens that lived about 160 thousand years ago in Africa. "Idaltu" means "firstborn". Fossils of Homo sapiens idaltu were discovered in 1997 by Tim White at Kherto Buri in Ethiopia. Although the morphology of the skulls indicates archaic features that are not found in later Homo sapiens, they are still considered by scientists to be the direct ancestors of modern Homo sapiens sapiens. 7.15. Homo sapiens is a species of the hominin family from a large detachment of primates. And it is the only living species of this genus, that is, us. If someone is reading or listening to this is not of our kind, write in the comments ...). Representatives of the species first appeared in Africa about 200 or 315 thousand years ago, given the latest data from Jebel Irhud, but there are still many questions. Then they spread almost all over the planet. Although in more modern form as Homo sapiens sapiens, well, a very intelligent person, appeared a little over 100 thousand years ago, according to some anthropologists. Also in early times, in parallel with people, other species and populations developed, such as Neanderthals and Denisovans, as well as the Soloy man or Javanthropus, the Ngandong man and the Callao Man, as well as others that do not fit into the species. A reasonable man, but according to dating, who lived at the same time. As for example: 7.15.1. The Red Deer Cave people are an extinct population of humans, the latest known to science, that does not fit within the variability of Homo sapiens. And possibly belongs to another species of the genus Homo. They were discovered in the south of China in the Guangxi Zhuang Autonomous Region in the Longlin cave in 1979. The age of the remains is from 11.5 to 14.3 thousand years. Although they may well be the results of cross-breeding between different populations that lived at that time. These issues will still be discussed on the channel, so a brief description is enough for now. And now, who watched the video from beginning to end, put the letter "P" in the comments, and if in parts then "H", only to be honest!
Why are people called people? For an adult, this question may seem somewhat "childish". However, it is often quite difficult for parents to answer it to a child. Let's find out how a reasonable person (homo sapiens) appeared and what is meant by this concept.
What is meant by the term "person"?
What is the meaning of the word "man"? According to encyclopedic data, a person is a living being endowed with reason, free will, the gift of thinking and speech. Based on the definition, only people have the ability to meaningfully create tools and use them in the course of organizing social labor. In addition, a person is subject to transmit his own thoughts to other individuals using a set of speech symbols.
The emergence of Homo sapiens
The first information about Homo sapiens dates back to the Stone Age (Paleolithic). It was during this period, according to scientists, that people learned to organize themselves into small groups in order to jointly search for food, protect themselves from wild animals, and raise offspring. The first economic activity of people was hunting and gathering. All kinds of sticks and stone axes were used as tools. Communication between people of the Stone Age took place through gestures.
At first, representatives of homo sapiens were guided in the organization of herd life solely by survival instincts. In this regard, the first people were more like animals. The physical and mental formation of Homo sapiens ended in the late Paleolithic period, when the first rudiments of oral speech, the distribution of roles began to occur in groups, and the tools of labor became more advanced.
Characteristic features of Homo sapiens
Why are people called people? Representatives of the species "reasonable man" differ from their primitive predecessors in the presence of abstract thinking, the ability to express their intentions in verbal form.
To understand why people are called people, let's start from the definition. Homo sapiens has learned to improve the tools of labor. At present, more than 100 items of a separate purpose have been found, which were used in the organization of life in groups by people of the Late Paleolithic era. Homo sapiens knew how to build dwellings. Although at first they were quite primitive.
Gradually, herd life was replaced by tribal communities. Primitive people began to identify their relatives, to distinguish between representatives of the species that belong to hostile groups.
The organization of a primitive society with the distribution of roles, as well as the ability to analyze the situation, led to the elimination of complete dependence on environmental factors. Gathering was replaced by the cultivation of plant foods. Hunting was gradually replaced by cattle breeding. Thanks to such opportunistic activity, the indicators of the average life expectancy of Homo sapiens have increased significantly.
Speech awareness
Answering the question why people are called people, it is worth considering the speech aspect separately. Man is the only species on Earth that can form complex combinations of sounds, memorize them and identify messages from other individuals.
The rudiments of the above abilities are also noted in some representatives of the animal world. For example, some birds that are familiar with human speech can quite accurately reproduce individual phrases, but do not understand their meaning. In fact, these are just imitative possibilities.
To understand the meaning of words, to create meaningful combinations of sounds, a special signal system is required, which only a person has. Biologists have repeatedly tried to teach individual creatures, in particular primates and dolphins, the system of symbols used for human communication. However, such experiments gave little results.
Finally
Perhaps it was precisely the ability of prehistoric man to organize life in groups, communicate, create tools, distribute social roles allowed modern people to take a dominant place on the planet among all living beings. Thus, it is assumed that the presence of culture allows us to be called people.
MAN REASONABLE(Homo sapiens) - a man of the modern type.
The course of evolution from Homo erectus to Homo sapiens, i.e. to the modern human stage, is just as difficult to satisfactorily document as the initial branching off of the hominid lineage. However, in this case the matter is complicated by the presence of several applicants for such an intermediate position.
According to a number of anthropologists, the step that led directly to Homo sapiens was the Neanderthal (Homo neanderthalensis or Homo sapiens neanderthalensis). Neanderthals appeared no later than 150 thousand years ago, and their various types flourished until a period of approx. 40-35 thousand years ago, marked by the undoubted presence of well-formed H. sapiens (Homo sapiens sapiens). This epoch corresponded to the onset of the Wurm glaciation in Europe, i.e. ice age closest to modern times. Other scientists do not connect the origin of modern humans with Neanderthals, pointing out, in particular, that the morphological structure of the face and skull of the latter was too primitive to have time to evolve to the forms of Homo sapiens.
Neanderthaloids are usually conceived as stocky, hairy, animal-like humans with bent legs, a protruding head on a short neck, giving the impression that they have not yet fully achieved upright posture. Paintings and reconstructions in clay usually emphasize their hairiness and unjustified primitiveness. This image of a Neanderthal is a big distortion. First, we don't know if Neanderthals were hairy or not. Secondly, they were all completely upright. As for the evidence of the inclined position of the body, it is likely that they were obtained from the study of individuals suffering from arthritis.
One of the most surprising features of the entire Neanderthal series of finds is that the least recent of them were the most recent in appearance. This is the so-called. the classic Neanderthal type, whose skull is characterized by a low forehead, a heavy brow, a sloping chin, a protruding mouth area, and a long, low skullcap. However, their brain volume was larger than that of modern humans. They certainly had a culture: there is evidence of funerary cults and possibly animal cults, since animal bones are found along with the fossils of classical Neanderthals.
At one time it was believed that the classical Neanderthals lived only in the southern and Western Europe, and their origin is associated with the onset of the glacier, which put them in conditions of genetic isolation and climatic selection. However, apparently similar forms are later found in some regions of Africa and the Middle East, and possibly in Indonesia. So wide use makes the classical Neanderthal man abandon this theory.
At the moment, there is no material evidence of any gradual morphological transformation of the classical type of Neanderthal into the modern type of man, with the exception of finds made in the Skhul cave in Israel. The skulls found in this cave are very different from each other, some of them have features that put them in an intermediate position between the two human types. According to some experts, this is evidence of the evolutionary change of the Neanderthal to modern humans, while others believe that this phenomenon is the result of intermarriage between representatives of two types of people, thus believing that Homo sapiens evolved independently. This explanation is supported by evidence that as early as 200–300 thousand years ago, i.e. before the advent of the classical Neanderthal, there was a type of human that most likely refers to the early Homo sapiens, and not to the "progressive" Neanderthal. It's about about well-known finds - fragments of a skull found in Swanskom (England), and a more complete skull from Steinheim (Germany).
Differences in the question of the "Neanderthal stage" in human evolution are partly due to the fact that two circumstances are not always taken into account. First, it is possible for the more primitive types of any evolving organism to exist relatively unchanged at the same time that other branches of the same species are undergoing various evolutionary modifications. Secondly, migrations associated with a shift in climatic zones are possible. Such shifts were repeated in the Pleistocene as glaciers advanced and retreated, and man could follow shifts in the climatic zone. Thus, when considering long periods of time, it must be taken into account that the populations occupying a given area at a certain moment are not necessarily descendants of populations that lived there for more than early period. It is possible that early Homo sapiens could migrate from the regions where they appeared, and then return to their former places after many thousands of years, having managed to undergo evolutionary changes. When the fully developed Homo sapiens appeared in Europe 35,000 to 40,000 years ago, during the warmer period of the last glaciation, it undoubtedly supplanted the classical Neanderthal that had occupied the same region for 100,000 years. Now it is impossible to determine for sure whether the Neanderthal population moved north, following the retreat of its usual climatic zone, or whether it mixed with Homo sapiens invading its territory.
For a long time in the Anthropogen, biological factors and patterns were gradually replaced by social ones, which finally ensured the appearance in the Upper Paleolithic of a modern type of man - Homo sapiens, or Homo sapiens. In 1868, five human skeletons were discovered in a Cro-Magnon cave in France, along with stone tools and drilled shells, which is why Homo sapiens are often called Cro-Magnons. Before Homo sapiens appeared on the planet, there was another humanoid species called Neanderthals. They inhabited almost the entire Earth and were distinguished by their large size, serious physical strength. The volume of their brain was almost the same as that of a modern earthling - 1330 cm3.
Neanderthals lived in the era of the great glaciation, so they had to wear clothes made from animal skins and hide from the cold in the depths of the caves. Their only rival in natural conditions could only be a saber-toothed tiger. Our ancestors had highly developed brow ridges, they had a powerful protruding jaw with large teeth. The remains found in the Palestinian cave of Es-Skhul, on Mount Carmel, clearly indicate that Neanderthals are the ancestors of modern humans. These remains combine both ancient Neanderthal features and features that are already characteristic of modern man.
It is assumed that the transition from the Neanderthal to the current type of man took place in the most climatically favorable regions. the globe, in particular, in the Mediterranean, Western and Central Asia, the Crimea and the Caucasus. Latest Research show that the Neanderthal lived for some time even at the same time as the Cro-Magnon man, the direct predecessor of modern man. Today, Neanderthals are considered to be a kind of side branch of the evolution of Homo sapiens.
Cro-Magnons appeared about 40 thousand years ago in East Africa. They populated Europe and within a very short period completely replaced the Neanderthals. Unlike their ancestors, the Cro-Magnons were distinguished by a large active brain, thanks to which they made an unprecedented step forward in a short period of time.
Since Homo sapiens lived in many regions of the planet with different natural and climatic conditions, this left a certain imprint on his appearance. Already in the era of the Upper Paleolithic, racial types of modern man began to develop: Negroid-Australoid, European-Asian and Asian-American, or Mongoloid. Representatives of different races differ in skin color, eye shape, hair color and type, skull length and shape, as well as body proportions.
The most important occupation for the Cro-Magnons was hunting. They learned how to make darts, arrowheads and spears, invented bone needles, with their help they sewed the skins of foxes, arctic foxes and wolves, and also began to build dwellings from mammoth bones and other improvised materials.
For collective hunting, housing construction and the manufacture of tools, people began to live in tribal communities, consisting of several large families. Women were considered the core of the clan and were mistresses in common dwellings. The growth of the frontal lobes of a person contributed to the complication of his social life and the diversity of labor activity, ensured the further evolution of physiological functions, motor skills and associative thinking.
Gradually, the technique of production of tools was improved, their assortment increased. Having learned to use the advantages of his developed intellect, a reasonable person became the sovereign master of all life on Earth. In addition to hunting mammoths, woolly rhinos, wild horses and bison, as well as gathering, Homo sapiens also mastered fishing. The way of life of people also changed - a gradual settling of individual groups of hunters and gatherers began in the forest-steppe regions abundant in vegetation and game. 
Man has learned to tame animals and domesticate some plants. This is how cattle breeding and agriculture appeared.
A sedentary lifestyle provided fast development production and culture, which led to the flourishing of housing and economic construction, the manufacture of various tools, the invention of spinning and weaving. Started to take shape new type management, and people became less dependent on the vagaries of nature. This led to an increase in the birth rate and the spread of human civilization in new territories. The manufacture of more advanced tools became possible due to the development of gold, copper, silver, tin and lead around the 4th millennium BC. There was a social division of labor and specialization of individual tribes in production activities depending on certain natural and climatic conditions.
We draw conclusions: at the very beginning, human evolution took place at a very slow pace. It took several million years that have passed since the emergence of the most ancient ancestors for a person to reach the stage of his development, at which he learned to create the first rock paintings.
But with the advent of Homo sapiens on the planet, all his abilities began to develop rapidly, and in a relatively short period of time, man turned into the dominant form of life on Earth. Today, our civilization has already reached the mark of 7 billion people and continues to grow. At the same time, the mechanisms of natural selection and evolution still work, but these processes are slow and rarely amenable to direct observation. The emergence of Homo sapiens and the subsequent rapid development of human civilization led to the fact that nature gradually began to be used by people to satisfy their own needs. The impact of people on the biosphere of the planet has made significant changes in it - the species composition has changed organic world V environment and the nature of the earth as a whole.
