Ancient DNA Sheds Light on Human-Neanderthal Interactions 45,000 Years Ago

A new study has narrowed the timeline of human-Neanderthal interactions to around 45,000 years ago, offering insights into our shared genetic history. The research, which involved scientists analyzing ancient human genes from remains in the Czech Republic and Germany, found Neanderthal DNA that pinpointed the mating period. A separate study also discovered that Neanderthal genes initially co-mingled with modern human DNA about 50,000 years ago, revealing their enduring legacy in modern humans. This genetic exchange left a lasting impact on modern humans, influencing traits like skin and hair color, nose shape, immunity, and metabolism, which may have aided early humans in adapting to environments outside Africa. The new research, published in Science and Nature, highlights how ancient genetic material continues to help unravel our origins. Scientists hope future studies will further clarify the complex interplay of ancient human groups, including Neanderthals and Denisovans, in shaping our genetic makeup.
