That is a reasonable theory, very logical, but as in History that's not
enough to prove it's true. In spite of this the idea seemed so "right" that
until recently nearly everybody thought it must be true; then the fossil
record proved that it's completely wrong.
Lucy lived 3 and a half million years ago, she could walk upright as well as
you or me, in fact from the neck down was very similar to modern people,
and yet, her brain was only slightly larger than a chimpanzee. The huge
increase in brain size came AFTER bipedalism developed and after a hand
evolved that could perform complex movement. It would seem much more logical
if a big brain came first, but that's not what happened and nobody
understands why.

I agree, that never made much sense to me, if anything it seems that
bipedalism would do better in a dense jungle that a open savanna, but if the
savanna theory is wrong that doesn't mean that the Aquatic Ape theory is
right.
