human migration

With the help of ancient and modern DNA samples, the researchers found some overlap between the spread of genetic ancestry and languages in East Asia.

In PNAS this week: placental expression risk scores for schizophrenia, ancient DNA-based analysis of human arrival in China, and more.

Initial paleoanthropological analyses had suggested an earlier arrival of modern humans in the region, contradicting molecular findings.

In Science this week: single-cell lineage tracing technique applied to study lung cancer metastasis, and more.

In Science this week: mapping the embryonic mouse heart, and more.

The analysis found that Archaic Age Caribbean populations had Central and northern South American-related ancestry, and no evidence of North American-related ancestry.

The analysis further indicated ties to Lapita populations that lived on Vanuatu and Tonga, suggesting Mariana Islanders may have helped settle Polynesia.

Investigators used sequence data for more than 200 ancient individuals from Mongolia and Russia to look at population migrations and interactions.

Genes in immune-related pathways were among those flagged when researchers used RNA sequencing on blood samples to look at functional genetic features in the population.

Data presented at the ASHG virtual meeting highlighted the population insights that can be gleaned from IDB profiles in populations, including loci linked to blood traits.
