That’s one finding of a recent study that evaluated the microbes and arthropods found in the treetop beds that chimpanzees make each night. Who knew that our closest animal relatives, the great apes — specifically chimpanzees — keep tidier bedrooms than we humans do? A group of researchers in […]

Enlarge (credit: Hawks et al. 2017) Homo naledi’s brain may have been small, but it looked surprisingly similar to ours, according to a new study which suggests that structure may have come before size in the evolution of hominin brains. Measurements of skull fragments indicate that Homo naledi’s brain was about the same size as […]
