Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here we use change-point analysis to estimate the timing of changes in the rate of hominin brain evolution.

Session is a project of the Loki Foundation. The Loki Foundation (registered as LAG Foundation, LTD) is a registered charitable foundation based in Victoria, Australia.
