In response to an article published by Jerome DeSilva of Dartmouth College and colleagues in 2021, anthropologist Brian Villmoare of the University of Nevada and chemist Mark Grabowski of Liverpool John Moores University have intervened.
According to the 2021 paper, the human brain may have lost up to 150 cubic centimetres of volume during the Iron Age, or roughly the size of a lemon.According to DeSilva’s team, the brain shrinks as a result of “self-domestication” and a preference for collective over individual thought.
Villmaore said that comparing the brains of sapiens to those of any other species was worthless and meaningless, in contrast to DeSilva’s study which examined 10 million years of evolution, including apes.
