Tropical Africa is home to an astonishing biodiversity occurring in a variety of ecosystems.
Past climatic change and geological events have impacted the evolution and diversification …

Acquired immunodeficiency syndrome (AIDS) of humans is caused by two lentiviruses,
human immunodeficiency viruses types 1 and 2 (HIV-1 and HIV-2). Here, we describe the …

Genetic data often exhibit patterns broadly consistent with'isolation by distance'—a
phenomenon where genetic similarity decays with geographic distance. In a heterogeneous …

Our closest living relatives, chimpanzees and bonobos, have a complex demographic
history. We analyzed the high-coverage whole genomes of 75 wild-born chimpanzees and …

Most great ape genetic variation remains uncharacterized,; however, its study is critical for
understanding population history,,,, recombination, selection and susceptibility to disease …

The accumulation of biodiversity in tropical forests can occur through multiple allopatric and
parapatric models of diversification, including forest refugia, riverine barriers and ecological …

Races may exist in humans in a cultural sense, but biological concepts of race are needed
to access their reality in a non-species-specific manner and to see if cultural categories …

Large brains and behavioural innovation are positively correlated, species-specific traits,
associated with the behavioural flexibility animals need for adapting to seasonal and …

Phylogeny estimation is difficult for closely related populations and species, especially if
they have been exchanging genes. We present a hierarchical Bayesian, Markov-chain …

We propose that people are genetic essentialists—that is, they tend to think of genetic
attributions as being immutable, of a specific etiology, natural, and dividing people into …
