Dear Scienceforums Community,
In this article by Beth Blaxland and Fran Dorey (2018) changes in brain size amongst different human species were measured and compared in cubic centimeters (cc).
Australopithecus afarensis: 450 cc
Homo habilis: 610 cc
Homo ergaster: 860 cc
Homo heidelbergensis: 1250 cc
Homo sapiens: 1350 cc
This makes total sense to me. Yet I chanced apon this article via a link at the end of another article also by Fran Dorey from two years after the first one.
Which stated that ,,Homo sapiens living today have an average brain size of about 1350 cubic centimetres which makes-up 2.2% of our body weight. Early Homo sapiens, however, had slightly larger brains at nearly 1500 cubic centimetres.''.
So I came to this forum because I wanted to have an exchange with archeologists about the actual state of science in 2024.
Did brainmass only increase over the course of time or did it actually get reduced in Homo Sapiens Sapiens?
