All rights reserved. [3][4][5], The divergence time between the Neanderthal and modern human lineages is estimated at between 750,000 and 400,000 years ago. In the last several decades, however, the driving question turned to mixing with modern humans.

Jan Hendon. It also remains unclear howor even ifsuch Neanderthal ancestry might play into the confusing mashup of features seen in many African hominin fossils, Hawks notes. In the same publication, it was disclosed by Svante Pbo that in the previous work at the Max Planck Institute, "Contamination was indeed an issue," and they eventually realised that 11% of their sample was modern human DNA.

However, in 2016 researchers published a new set of Neanderthal DNA sequences from Altai Cave in Siberia, as well as from Spain and Croatia, that show evidence of human-Neanderthal interbreeding as far back as 100,000 years ago -- farther back than many previous estimates of humans migration out of Africa (Kuhlwilm et al., 2016).

This would be an interesting thing to follow up on.. Worked at National Health Service (NHS) Upvoted by. 3.

The analysis was carried out by a machine-learning algorithm that could differentiate between components of both kinds of ancestral DNA, which are more similar to one another than to modern humans. The results suggest that modern Africans carry an average of 17 million Neanderthal base pairs, which is about a third of the amount the team found in Europeans and Asians. Certain regions have See full answer below. Other groups have hypothesized that early migrations in and out of Africa might have mixed Neanderthal DNA into the continents human populations, explains Svante Pbo, a geneticist at the Max Planck Institute for Evolutionary Anthropology who wasnt involved in the study, in an interview with Gizmodos George Dvorsky. Our work highlights how humans and Neanderthals interacted for hundreds of thousands of years, with populations dispersing out of and back into Africa, study author Joshua Akey, a geneticist at Princeton University, tells Bruce Bower at Science News. With the discovery of Neanderthal ancestry across African populations, researchers have now found traces of ancient interbreeding in all populations studied so far. Please be respectful of copyright. [32], 2018 research indicates interbreeding between Neanderthals and modern humans led to the exposure of each species to unfamiliar viruses. Well that cant be right, he recalls thinking at the time. The genetic atlas revealed new information about health risks, ancient political borders, and the influence of Vikings.
