Very well said, Angilion.

To feminazis, there's no difference between blue whales and humans, because
they both "evolved" from the same "common ancestor", so it must somehow make
sense to them to make such a suggestion.

But to the rest of the normal people in the country, namely the 91% who
reject this "theory" of evolution, human beings have a unique role on the
planet because they are a unique species, so to suggest that we must make
comparisons across species is merely the easiest way out of replying
logically to your question.

TIMSS and GRE are evidence enough of the correlation between human brain
size and human intelligence--but this forum sure did add some nice data to
the equation, didn't it?
