human migration

A University of Chicago-led team examined the genomes of more than 3,500 Sardinians and found within-island genetic substructure and outside admixture.

Individuals with northern genetic ancestry were buried with more grave goods than individuals with local southern genetic ancestry, the researchers found.

At a 7th century German burial site, researchers saw genetic markers from populations in northern Europe, southern Europe, and the Mediterranean.

Diet- and height-related variants were selected for in a Flores Island pygmy population, according to a study, which also provided insights into the population's history.

Using bulk DNA samples produced from more than 5,000 subfossil bone fragments, researchers retraced species trajectories and extinctions over time in New Zealand.

With genome sequences or genotyping profiles for 280 Native American and mestizo individuals, researchers explored population history and dynamics in Peru.

Researchers analyzed a dozen genomes from individuals who lived in Morocco or Iberia during the Neolithic to find a complex population history in North Africa.
