In Genome Biology this week: analysis of tuberculosis samples from the 1600s, tool to detect variants affecting RNA-binding protein activity, and more.
In Science this week: analysis of ancient Caribbean islanders' genomes suggests at least three waves of migration into the region, DNA barcoding of microbial spores, and more.
Ancient samples from more than a dozen archaeological sites suggests population movement from South America preceded by at least two earlier migration waves.
Ancestry patterns appeared to shift in parts of northern China during the Neolithic and Bronze Age as populations transitioned to farming-focused and pastoralist subsistence strategies.
Investigators explored population dynamics during the shift to farming with new sequence data from more than 100 individuals from present-day France and Germany.
Independent research teams have tackled the genetic history of the Levant, Anatolia, and other parts of the Near East to retrace population movement and mixing since the Bronze Age.
Researchers teased apart population interactions in Siberia's Lake Baikal region as far back as the Upper Paleolithic, identifying early genetic ties to individuals migrating to the Americas.
