According to the British " Daily Mail ", the latest study shows that most Neanderthals and early humans occurred about 50,000 years ago, and are located in the " Near East region" in the Iraq area. It is reported that experts have obtained this conclusion by analyzing the facial structures of skulls of 13 Neanderthals, 233 Prehistoric Homo sapiens and 83 modern humans.
These skulls were found in different locations in Asia, Europe and Africa, respectively, with the aim of finding signs that Neanderthals influence human facial anatomy. Steven Churchill, a co-author of the research report and a professor of evolutionary anthropology at Duke University in the United States, said: "Neanderthals have a large face, but body shape alone cannot prove any genetic connection between humans and Neanderthals. Our work is to conduct a more comprehensive analysis of facial structures. Some skull determinations show the impact of Neanderthals on human facial anatomy, which allows researchers to determine whether the Neanderthals are the location where most hybrids occur. The hybridization phenomenon mainly occurred 50,000 to 40,000 years ago, when modern humans and Neanderthals in the Paleolithic Age lived in the same period and the same region."
Facial shape and development status can reflect changes in gene composition. Scientists compared measurement results of similar facial structural characteristics to determine whether there was obvious hybridization phenomenon in the ancient skulls they analyzed. The results show that both changes occurred after early modern humans and Neanderthals crossed.
At the same time, the study tracks and analyzes how humans migrate and interact over time by evaluating facial morphological characteristics. The results show that the Near East is an important crossroads, both geographically and in the context of human evolution .
