Brain Size Expansion
The emergence of Archaic Homo sapiens is sometimes used as an example of punctuated equilibrium. This occurs when a species undergoes significant biological evolution within a relatively short period. Subsequently, the species undergoes very little change for long periods until the next punctuation. The brain size of Archaic Homo sapiens expanded significantly from 900 cubic centimeters in erectus to 1300 cubic centimeters. Since the emergence of archaics, brain size has remained stable up until the present.

Will them away while yet unborn?” Let every woman ask.”
