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.

Famous quotes containing the words brain size, brain, size and/or expansion:
“...here he is, fully alive, and it is hard to picture him fully dead. Death is thirty-three hours away and here we are talking about the brain size of birds and bloodhounds and hunting in the woods. You can only attend to death for so long before the life force sucks you right in again.”
—Helen Prejean (b. 1940)
“Thou hast no more brain than I have in mine elbows.”
—William Shakespeare (15641616)
“Beauty depends on size as well as symmetry. No very small animal can be beautiful, for looking at it takes so small a portion of time that the impression of it will be confused. Nor can any very large one, for a whole view of it cannot be had at once, and so there will be no unity and completeness.”
—Aristotle (384 B.C.322 B.C.)
“Artistic genius is an expansion of monkey imitativeness.”
—W. Winwood Reade (18381875)
