Scrutiny or not it is not a defense. People who favor more or less
savanah are constantly scanning for evidence in support of their
theory or against it. If africanus is truely an intermediate to
humans and the C-13 studies are correct it could be said that Savanah
is clearly in the range of early homo. This does not mean it was the
range, or even the subset that leads to us. What it does say however,
is so far there is substantively more in-situ evidence for expanding
into savanah than into aquatic. It does not mean that humans were
strcitly savannah dwellers.
  How can I make the ape theorist of this world understand. Science
is not about knowing, its about asking and waiting for answers.
