To answer just one question at a time since a compound answer to
several is not comprehensible, the problem with specialists is
programming. Computer science is, even now, at about the point where
you could craft the software to eat a particular kind of grass and
wander around until the robot found it.

But as the variety of the diet increases, and the variety of the
ecosystems various food sources are found in, the complexity of the
program increases exponentially, and you need a central processing
unit larger than anything now available to match what the hominids in
the early Chad riverine system were confronted with.

What you are stating here is, plainly, nonsense. Rainforest habitats
are easily the most complex habitats on this planet yet our smaller
brained chimpanzee ancestors resided and still reside in such
habitat. Moreover it couldn't be more obvious that human intellect
involves social adaptations and, therefore, the scenario that involved
the origins of human intellect must have involve selection for these
social adaptations.

Chimps exist on a relatively limited diet.

Why do you say this? References?

The Chad environment would
also have included stands of fruit & nut trees where the water table
was reliable enuf.

Okay.

Hominids would have had access to everything the
Chimps ate, and much more besides.

This makes no sense. Why would early hominids (which evolved from
chimps) have resided contemporaneously with chimps. There were no
chimps, or the hominid were the chimps in this habitat.

I frankly dont think anyone gives a *** that much what I have to say,
much less what you think of it.

Don't worry about what other people think. Most of them are busy
trying not to think.

If you would provide links to data you
think I missed,

I don't necessarily think you missed any of the data.

I, and perhaps others, would be grateful. In this
thread, I most would like data on just how extensive this mixed
ecosystem was, and how long it endured.

It still exists. The conditions in India, for example, are (by my
estimation) about the same as those in East Africa 4 to 7 mya. (Of
course we have to keep in mind the effects of ecologically dominant
human population which, of course, didn't exist to the same extent 4
to 7 mya.

How far down bedrock or impermeable clay layers were would have had an
enormous effect on the consistency of a water supply for tree roots.
Likewise, top soils that are either sand or clay have very different
kinds of plant life, and would have made digging tubers easy or
difficult. The wide flat molars on the Chad skull look to be suited
more for tubers than meat,

Seeds, nuts, etc.

but an analysis of how badly worn they were
would be instructive.- Hide quoted text -
