While in the past scientists believed that the neocortex of the brain was the "crowning achievement" of evolution, they've now found that the cerebellum expanded up to six times faster than anticipated throughout the evolution of apes.

"Our results highlight a previously unappreciated role of the cerebellum in ape and human brain evolution that has the potential to refocus researchers' thinking about how and why the brains in these species have become distinct and to shift attention away from an almost exclusive focus on the neoco...
