Re: BELL CURVE CRITIC EXPOSED?

It seems to me that anthropology is the only biological
discipline represented among the comments thus far. A rather
active area of molecular biology is being neglected. Perhaps
this is overlooked because people studying the matter often say
nothing about 'race' -- more precise and less emotionally
charged terms are preferred. For anyone interested in pursuing
this, some of the references below might be useful. Note that
most are 1-2 years old, and should be presumed obsolescent at the
very least. Those not indicated as books are journal articles.

General disclaimer: To the extent that I'm concerned with
evolutionary issues, they concern the coevolution of hosts and
their parasites. I'm not a) a gene jockey myself, b)
professionally involved in human evolution at all, or c) an
initiate of the phenetic-cladistic holy wars. I'm providing the
pointers below because no one else has, not because I wish to
claim expertise in the field.

a cautionary tale about using any single piece of genetic

but not the whole story.]]

[[This is a protein allele based study, not a direct genome
examination. It deals both with the authors' proposed tree and
technical reasons for preferring one method of tree construction
over another. This one contains some interesting trees, and is
worth looking at even if much of the text remains, let's say,
opaque.]]

and the tree is based on a different algorithm. The major
branching patterns are very similar.]]
