Human evolution is marked by a significant increase in the total brain size relative to body size, referred to as encephalization. Although increased encephalization is a clear hallmark of human cognitive and cultural evolution, there is little consensus on the causes of such phenomenon. In part, this lack of agreement reflects the difficulty to test directly numerous hypotheses proposed to explain the brain.

3 Jul 2017. Here we argue that the efforts to identify the correct explanations for brain size evolution have foundered on four major issues. They argued that all non- human primate societies are essentially competitive; hence, the MIH (as originally proposed by Humphrey ) provides a. Indeed, these executive function competences correlate with neocortex volume across primates .
The evolution of larger brains in the last 3 million years. NOTCH2NL’s location on the genome, incorrectly mapped until recently, is further support for its role in human brain size. Duplications.
