Scientists have made a breakthrough in understanding the history of human evolution by pinpointing when humans and Neanderthals mixed and mingled. The research, published in journals Science and Nature, suggests that this event occurred around 45,000 years ago.
Researchers analyzed ancient genes from human remains found in Europe to reconstruct the timeline. They focused on two samples: a woman’s skull from the Czech Republic and bone fragments from an early human population in Germany. These samples revealed snippets of Neanderthal DNA that suggested a mixing period around 45,000 years ago.
The study also sheds light on the genetic legacy of Neanderthals, who coexisted with modern humans in Europe. Researchers found that many modern-day genetic quirks, such as skin color and hair color, are linked to Neanderthal ancestry. The discovery also highlights the presence of Denisovan genes in human DNA.
The study’s findings provide valuable insights into human evolution and raise questions about our ancestral origins. As Dr. Rick Potts, director of the Smithsonian’s Human Origins program, noted, “Out of many compelling areas of scientific investigation, one of them is: well, who are we?” The research opens up new avenues for genetic studies to help scientists better understand what makes us human.
