  New Scientist (5-Dec-92) had a seven page supplement "The great Brain 
race", which was one of the many supplements they have had on the Secret
Life of the Brain.

  It is relevent to this discussino but I am sending it under a new
subject heading  = brainsize - the great brain race.

But I thought I would summary the questions it answers so anyone 
reading this subject who is interested will not miss it.

   Why did mammals evolve large brains 250 Ma?
   Why did mammals evolve even larger brains 65 Ma.?
   Why did primates evolve brains large compared to other mammals?
   How do primates grow such large brains?
   Why did humans evolve such large brains compared to primates?
   Is size the only way humans brains differ?
