Re: [asa] Re: Endgame

Bernie,
In considering human evolution, your need to remember that the fetal head
is as large as can be accommodated by the mother's pelvis. So the notion
of bigger brains is nixed. The pictures of aliens with big heads and
narrow hips are an impossibility. There was a recent report that the
Neanderthal newborn had a head almost identical in size to that of Homo
sapiens. So size was preserved across species. Of course, if males and
females diverge, with the females becoming sessile because of the vast
increase in hips to accommodate a birth canal big enough to pass a keg,
brain size may increase tremendously.
