That interbreeding left Eurasians with many genes inherited from our Neanderthal ancestors, which in total make up between 1% and 2% of our genomes today. A more precise timeline for modern human interactions with Neanderthals can help scientists understand when humans emigrated out of Africa and peopled the globe, while understanding the DNA that Neanderthals shared with our ancestors provides information on the role Neanderthal genes play in human health. The genome-based estimate is consistent with archeological evidence that modern humans and Neanderthals lived side-by-side in Eurasia for between 6,000 and 7,000 years. The analysis, which involved present-day human genomes as well as 58 ancient genomes sequenced from DNA found in modern human bones from around Eurasia, found an average date for Neanderthal-Homo s apiens interbreeding of about 47,000 years ago. Previous estimates for the time of interbreeding ranged from 54,000 to 41,000 years ago. The new dates also imply that the initial migration of modern humans from Africa into Eurasia was basically over 43,500 years ago. .... https://www.science.org/doi/10.1126/science.adq3010 Neanderthal ancestry through time: Insights from genomes of ancient and present-day humans https://www.nature.com/articles/s41586-024-08420-x Earliest modern human genomes constrain timing of Neanderthal admixture
