Human brain’s voice area shows selective response to chimpanzee calls
Reported by AI Image generated by AI Fact checked
Researchers at the University of Geneva have found that specific regions of the human auditory cortex respond particularly strongly to chimpanzee vocalizations compared with those of other primates, including bonobos and macaques. The work, published as a reviewed preprint in eLife, suggests that human brain areas involved in voice processing are also tuned to certain nonhuman primate calls, reflecting shared evolutionary and acoustic roots.
A pair of twin proboscis monkey babies was born at the Camp Tim Roberts Proboscis Monkey Research Station on Curiak Island, South Kalimantan, in mid-June 2026.

New research indicates that the earliest primates originated in cold and dry regions of North America rather than tropical forests. The findings challenge long-held assumptions about primate evolution.
