Ancient DNA reveals the mysterious collapse of Europe's megalith builders

DNA migration genetics Homo sapiens human origin

DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments.

The Neanderthal “love story” isn’t what the DNA actually shows

DNA migration reproduction evolution genetics Homo sapiens

Claims that Neanderthal men "preferred" Homo sapiens women may make for catchy headlines, but the underlying research does not actually show prehistoric romance. The genetic evidence only points to an uneven pattern of DNA inheritance, which could have been shaped by biology, migration, or social organization. Archaeological evidence suggests Neanderthal groups may have followed traditions where women moved between communities, opening the door to far more complicated explanations than simple at

Ancient Denisovan DNA still shapes human immunity today

DNA genetics human origin

Ancient encounters between humans and the mysterious Denisovans are still shaping people today. By analyzing genomes from populations across the Pacific, researchers uncovered evidence that the ancestors of Near Oceanians interbred with at least three different Denisovan groups, leaving behind genetic variants that remain active in modern humans.

Ancient DNA shared with Neanderthals may explain human language

DNA genetics human origin

A tiny set of ancient genetic “switches” may have played a surprisingly large role in making human language possible. Researchers found that these DNA regions, which act like volume controls for genes involved in brain development, have an outsized influence on language ability despite making up less than 0.1% of the genome.
