*This* is more like a hypothesis. *This* is something
that is potentially testable. Just as my hypothesis
presents testable predictions, like the prediction that
the fossil record will reveal the sudden emergence of a
recurring dry season in Africa at about 8.1 mya, this notion
also has the potential to present a testable prediction
that can be tested in the paleoclimatological record.
So why doesn't Algis supply us the details? When did
these floods supposedly happen? Give us dates so we
can test it. You'll note that I have no trouble doing
this in the context of my hypothesis.
Also, what, precisely, was the adaptive behavior?
Again, you'll note that I had no trouble delineating
this in the context of my hypothesis. Delineate the
advantages. Delineate the disadvantages. Weigh them
against each other. Evolution always involve tradoffs.
Delineate these tradeoffs. I don't see Algis, or
anybody, making any effort at all in this regard. To him
(and this is a conceptual error that Algis shares with
many anthropologists) it is foregone conclusion that
bidalism is adaptive. He's so deluded he thinks it's
just a matter of finding some aspect in the environment
that would make it easy to achieve a bipedal stance and
the rest takes care of itself. This isn't McGinnian at
all. It's Lamarkian.
For Algis's vague notion to be truly McGinnian it must
live up to the same level of detail of my hypothesis.
It doesn't come close. (Nor does any other hypothesis,
for that matter.)
