According to the research, humans interfere with four species of extinct hominids: while modern Homo sapiens was displaced from Africa and the rest of the world, they found and interfered with at least four different hominid species, the University of Adelaide, According to a new Australian research.
Surprisingly, of these hominids, only Neanderthals and Denisovans are currently known; Other names have been discontinued and found only as traces of DNA that survive in several modern populations.
Reconstruction of Homo florescensis, a species of extinct hominids that lived 74,000 and 18,000 years ago at the bottom of the Indonesian island. Each of us takes us to the genetic traces of the events of these previous mixtures, DRS. João Teixeira is co-author of an article published in Proceedings of the National Academy of Sciences.
These archaic groups were very broad and genetically diverse, and survive in each of us. Its history is an integral part of how we form “For example, approximately 2% of all current populations show Neanderthal ancestry, which means that Neanderthal’s mixing with the ancestors of modern humans occurred shortly after leaving Africa., Probably between 50,000 and 55,000 years ago. Middle East. “
But as the ancestors of modern humans traveled further, they found themselves in the East and mixed with at least four other groups of archaic humans. Dr. Teixeira announced that the island of Southeast Asia was already a crowded place.
Which we call modern humans, who arrived in the region 50,000 years ago. “At least three other archaic human groups have occupied the region, and the ancestors of modern humans were assimilated before the extinction of archaic humans.”
In his new research, Drs. Teixeira and his colleague, Professor Alan Cooper, analyzed genetic, archaeological and fossil evidence, as well as additional information on reconstructed migration routes and records of fossil vegetation.
The scientists discovered that there was a mixed phenomenon among modern humans and a group around South Asia, which they called the extinct hominid 1 (E1). Other Christian islands originated with Denisovans in Southeast Asia and the Philippines, and with another group, called extinct hominid 2 (EH2) in Floors, Indonesia.
Approximate trajectory (yellow and red arrow) of the movement of anatomically modern humans across the island of Southeast Asia about 50,000 years ago: populations of modern predators with genetic data are shown in red and populations grown in black are shown in color.
The predicted genomic content of EH1 (purple), Denisovan (red), EH2 (brown) and non-parasitic (gray) is shown in the pie chart as the relative proportions observed in the Australian-Papuans (complete circles).
All populations with large amounts of Denisovan genomic material are located east of the Wallace line; The incidence of independent introversion with Denisovan groups has been estimated separately for the Australian ISA population: Papua, Philippines (red class 2) and for the Philippines (red class 4).
The signal for a different introduction with an unknown hominin in flowers recorded in genomic data of the current population remains less secure (brown circle 5); The exact location of introverted events 2, 4 and 5 is currently unknown. “We knew that history outside of Africa was not simple, but it seems to be more complex than we thought.”
Arctic human species found in a cave of 14,000-year-old red bone antelopes: an archaic species of the Chinese genus Homo, which for a long time was believed extinct, possibly already 14,000 years ago, among the remains of a thigh bone. The people of Red Deer Cave of China. Artists rebuilding Red Deer Cave.
Peter Scouton image. A 14,000-year-old bone head, a partial female, was found in 1989 in Maludong (Red Deer Cave), Yunnan, southwest China, with fossilized remains of mysterious dark-skinned people. According to a study published in the journal PLoS One. Early bone and bone erections h. Hillis looks like a woman.
Like the primitive Homo habilis species, Maludong’s thigh bone is very small, with the professor, co-author, at the Yunnan Institute of Cultural Relics and Archeology in China. “The axis is narrow, the outer layer (or layer) of the axis is very thin; Shaft walls are reinforced (or with buttocks) in areas of high stress.
The neck of the femur is long; And for the primary flexor muscle of the hip (lower trochanter), the muscular insertion is very large and strongly forward. “With an estimated body mass of about 50 kg, the Maladong person was much smaller according to the human standards of Premier and Ice Age.
There is a possibility that clues about the dominant species with modern humans are found in continental Asia in advance, but the University of New South Wales Dr. Darren Cornow said the case should be made slowly with more bone discoveries.
Main co-author of the study. The scientists said their discovery is controversial because until now, it was thought that the most important younger humans in continental Eurasia (Neanderthals and Denisovans) had died anatomically shortly after the modern monkey, 40,000 years ago. Sapiens entered the region.
When the same team announced the discovery of the remains of the people of Red Deer Cave in 2012, it divided the scientific community.
At that time, the scientists speculated that the bones may represent a new unknown species, or perhaps the population of early and early-looking modern humans, who inhabited the region more than 100,000 years ago.
“We first published our findings about the bones of the skull because we thought they would be the most revealing, but we were surprised by our study of the thigh bone, which showed that it is much more primitive than the skull.”
The moment of human development describes where Maludong’s femur probably fits. The new discovery once again points to at least a few Maludong bones that represent a dominant mysterious species.
The team suggested in another recent PLoS ONE article that Longlin Cave’s skull in China is possibly a hybrid between anatomically modern Homo sapiens and an unknown archaic group, possibly presented by Maludong to Femur.
The researchers said: “The Maludong fossil is possibly a specimen of archaic populations that lived in a biologically complex area of southwest China until about 14,000 years ago.”
The professor said: The unique climate due to the elevation of the Tibetan plateau and the climate of southwest China has possibly provided a refuge for human diversity.
