Recent genetic studies have provided compelling evidence that modern humans and Neanderthals interbred approximately 47,000 years ago. This interaction has significant implications for our understanding of human evolution, migration patterns, and the genetic diversity of contemporary human populations. The findings highlight the complexities of human ancestry and the role of Neanderthals in shaping the genetic makeup of modern humans.
