And then on top of that is the *worst* problem of all.... there seems to
be no real correlation between the archaeological record and the increase
in brain size. This I find MOST frustrating, annoying, and provocative.
Are there any GOOD differences in the toolkit of late erectus and early
sapiens? What about 'archaic' and modern sap? And worstest of all,
perhaps, any good physical differences between early moderns and the
moderns who appear to have done nifty things like art, agriculture and the
like....

Rabbits exist, hence we may speak meaningfully to the evolution of
the rabbit. Some people attempt to study the evolution of
human intelligence. We may well have a real problem here.
