Evolutionary divergence of neuroanatomical organization and related genes in chimpanzees and bonobos

This paper from our very own CASHP examines brain difference in chimpanzees and bonobos from both an anatomical and genomic level. They find that bonobos brains have reduced in a number of parameters, brain size in both males and females and white matter, and chimpanzees brains have increased. Despite these anatomical changes They see no significant difference in genomic structure, apart from some small truncations in some genes, however no observable difference in protein evolution. Suggestion that bonobos brains have shrunk because of self-domestication, similar to what is hypothesised in humans are discussed.
