Abstract:The fact that rapid brain size increase was clearly a key aspect of human evolution has prompted many studies focussing on this phenomenon, and many suggestions as to the underlying evolutionary patterns and processes. No study to date has however separated out the contributions of change through time within- vs. between- hominin species whilst simultaneously incorporating effects of body size. Using a phylogenetic approach never applied before to palaeoanthropological data, we show that brain size increase ac… Show more
