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.
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.
