Admixture of Stone Age European Farmers, Hunter-Gatherers Led to Genetic Loci Under Selection
Using natural selection-focused analysis, researchers saw overrepresentation of hunter-gatherer sequences in an immune-related region in admixed ancient European farmers.
Tibetan Plateau Population Relationships, Adaptations Assessed With Ancient Genomes
With new sequences for 89 ancient individuals, researchers identified shared and distinct ancestry patterns within Tibetan Plateau populations going back 5,100 years.
Chagas Disease Protective Variant Found in Indigenous Amazon Populations
With genome profiles for more than 100 individuals from populations in the Amazon, investigators focused in on selection signatures linked to Trypanosoma cruzi response.
Large-Scale Genome Sequencing Study Unravels History, Traits of Understudied African Populations
Researchers at UPenn and their colleagues sequenced the genomes of 180 Africans from 12 indigenous populations, identifying more than 32 million novel SNPs.
Sequencing Study Uncovers Genes Under Positive Selection in Large, Long-Lived Sea Creatures
Sequences from a range of cetacean species suggest the aquatic environment has exerted selective pressure genes involved in growth, cancer suppression, and other features.
