Sweet Potato Puzzle

Researchers turn to genetic analysis to unravel how sweet potatoes spread from the Americas to Polynesia, the New York Times reports.

With genome sequences and/or array-based genotypes for ancient and modern individuals in Patagonia, researchers retraced hunter-gatherer population history.

In Nature this week: sequenced genomes of five additional Neanderthals, and more.

The researchers estimated that the newly sequenced late Neanderthals likely split from the lineage leading to much older Altai Neanderthal roughly 150,000 years ago.

In Science this week: analysis of DNA from ancient North Africans, and more.

By sequencing a handful of individuals who lived in Morocco some 13,900 to 15,100 years ago, investigators found clues to past population mergers in North Africa.

New ancient DNA studies have revealed female-biased migrations into Bavaria during the Middle Ages and more ancient Neolithic farmer expansions into Iberia.

Sequence data for ancient and modern individuals in Remote Oceania and beyond suggests early populations were replaced without corresponding language changes.

Using genomic data for hundreds of ancient Europeans, research teams retraced the spread of the Beaker complex culture as well as interactions between pastoralists and hunter-gatherers.
