Neolithic hunter-gatherers and farmers lived side by side without having sex for more than 2,000 years, new research suggests.
Analysis of fossil skeletons unearthed in a cave in Germany revealed that the two populations remained mostly separate for two millennia, despite living in the same region.
"We thought up till now that shortly after the introduction of farming in central Europe all hunter-gatherers kind of vanished," said study co-author Ruth Bollongino, an archaeogeneticist at the Johannes Gutenberg University in Germany. "This is mainly because we hardly find any artifacts. We have absolutely no ongoing proof of a hunter-gatherer lifestyle after the early Neolithic," around the time when farmers were first migrating from the Middle East.
