Abstract
Summary of the research findings
New research on the Lapedo Child shows evidence of a human-Neanderthal hybrid, dated to around 28,000 years ago, extending the timeline of Neanderthal survival. The conventional theory is that humans and Neanderthals interbred between 40,000 and 50,000 years ago, with Neanderthals going extinct not long after that. A new study has determined that the skeleton of a child with both human and Neanderthal traits found in central Portugal (the Lapedo Child) is approximately 28,000 years old. Advanced compound-specific radiocarbon analysis (CSRA) of amino acids isolated from bone collagen produced an age estimate between 27,780 and 28,850 years ago. The study also examined associated material (rabbit bones, red deer bones, charcoal) and burial context, and suggests ritual behavior and that the burial site was abandoned after the interment. The article reports that the findings (published in Science Advances, doi: 10.1126/sciadv.adp5769) have implications for the timing and duration of human–Neanderthal genetic exchange.
