Researchers uncovered examples of potentially beneficial copy number variants introgressed from Neanderthals and Denisovans under positive selection in Melanesians.
For the first phase of the SG10K project, researchers sequenced thousands of Chinese, Malay, or Indian individuals from Singapore, uncovering new variants and population insights.
Using ancient DNA profiling, isotope analyses, and archeological clues, investigators saw high-status, male-centered families, along with more modest graves for unrelated individuals.
By sequencing an Indus Valley Civilization representative and related individuals, investigators learned more about the South Asian ancestry, farming history, and languages.
A genomic analysis of ancient and modern samples revealed population clusters and ancestral contributions stemming from historical migrations and admixture events.
Researchers warn that there are finite ancient samples for genetic analysis and argue that policies should be in place to ensure they are studied responsibly.
Researchers uncovered six clusters among the more than 2,500 individuals they analyzed and noted varying degrees of Norse Viking ancestry in their cohort.
