...apsids

[BPC.APA@email.apa.org (Considine, Blaise)]

To Sean (snake)--I saw it as the diapsids had 2 holes behind the eye (for 
a total of three) whereas the synapsids had 1 (totaling 2). I found it 
confusing in that (I could swear) the narrator said that both types of 
set ups allowed for bigger brains while both avoided squeezing the brain. 
The difference allowed for different jaw configurations. Also, there was 
that bit about the development of the ear, but  I'm not sure just how 
that tied in to the number of holes in the skull. I guess that's the 
problem with a half-hour show liberally laced with commercial 
interruptions. Advice from the experts would be appreciated.
