Genomic polymorphism across centromeric regions of humans is organized into large-scale haplotypes with great diversity, including entire Neanderthal centromeres.
The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.
Ezh2 and Arid1a oppose each other to control expression of Cdkn2a to coordinate tooth furcation development and ultimately determine the number of roots in mouse molars.
A late Middle Pleistocene age for Homo naledi demonstrates a diversity of hominin species in Africa at this critical time in the archaeological record.
Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.
Animals living alongside humans have multiple copies of the gene for alpha-amylase, the enzyme that breaks down starchy foods, and high levels of this protein in their saliva.
