Apparently not linear, according to this article.
The correlation between brain size and intelligence isn't so much what I was asking as is what the evolution in cognitive growth the brain has experienced in the recent past.
The brain is a fascinating complexity and I wonder to what neurological extent has it changed (if any) since the inauguration of the current human species.
I understand current thought alludes to species evolving in "leaps," as if a species "jumps" to a higher plateau of biological and psychological advancement and basically stays there until the next leap.
I may have just answered my own question...any other thoughts?

Is nt this the core topic in courses like physical anthropology, and human evoution
such as the answer is not a few lines but more like a term of lecctures ?
The problem is limited: Homo sapiens sapiens can't change too much without becoming another species.
100 000 y in human evolution is not a long period (pleistocene) I thought we were the same 100 000 y ago - four generation in 100 y which means 4000 generations which I thought was peanuts in terms of evolution

The problem with human evolution is that it would be nice is
A gave way to B which evolved into Austrolpithecus and then into Man (H Sapiens)
The fossil record doesnt bear this out - I think 100 000 we were co-exisitng with neandethals
Raymond Dart prof of anat in Witswatersrand was big in this - he desribed the Taung Child 1928 - australopithecus.
They apparently went back to him just before his death around 1960 and said did you find in your strata parallel species or changing one into the other ?
and he said apparently even in 1928 it was obvious they were co-existing but they thought no-one would believe them.....

god no wonder you are confused:
http://en.wikipedia.org/wiki/Hominidae
seems to written by someone in the know, and the overall message seems to be - we dont have the first idea !
