Background Skin color is a well-recognized adaptive trait and has been studied extensively
in humans. Understanding the genetic basis of adaptation of skin color in various …

The recent availability of genomic data has spurred many genome-wide studies of human
adaptation in different populations worldwide. Such studies have provided insights into …

The emergence of agriculture in West-Central Africa approximately 5,000 years ago,

Positive natural selection can lead to a decrease in genomic diversity at the selected site
and at linked sites, producing a characteristic signature of elevated expected haplotype …

The genetic history of African populations is increasingly well documented, yet their patterns
of epigenomic variation remain uncharacterized. Moreover, the relative impacts of DNA …

Few studies exist of allomaternal nursing in humans. It is relatively common among some
cultures, such as the Aka and Efé hunter-gatherers of the Congo Basin, but it does not occur …

African rainforests support exceptionally high biodiversity and host the world's largest
number of active hunter-gatherers [1–3]. The genetic history of African rainforest hunter …

Genetic studies have revealed that most loci associated with osteoarthritis (OA) show ethnic
stratification, with limited overlap between Asian and European populations. Consequently …

Central Africa, a forested region that supports an exceptionally high biodiversity, hosts the
world's largest group of hunter-gatherers, who live in close proximity with groups that have …

African Pygmies practicing a mobile hunter-gatherer lifestyle are phenotypically and
