Story summary

Neanderthals were not extinct but were gradually absorbed into Homo sapiens through sustained interbreeding over 10,000 to 30,000 years, according to Andrea Amadei of University of Rome Tor Vergata.
The study identifies genetic admixture as a central factor in diluting Neanderthal genes.
Environmental changes and resource competition, plus evidence of violent interactions, also contributed.
Modern humans inherit 1 to 4 percent of their DNA from Neanderthals, indicating a lasting legacy.
