My take on Schwartz's "orang=closer than African apes" is that he's
barking up the wrong tree (ie. using the wrong method for the job of
determining relatedness). I'll grant him that some, indeed many, of
the molecular guys involved in human evolutionary studies are arrogant
beyond what they should be; not that this is particularly different from
a lot of bone diggers-describers, however. But the fact is that for the
study of relatedness of living species, blood, genes, etc. are the right

Now the molecular guys do take things too far when they suggest that
theirs are also the *only* tools to be used for questions of timing, but
they are certainly one of the real good tools there as well. But for
nail of relatedness they certainly have the proper hammer.

Tanner has, in *The Evolution of Human Behavior: Primate Models* (1987,
Kinzey, ed.) a chart with as many of the various relatedness studies
listed with conclusions (when conclusions were made), starting with
Nuttall's blood studies early in the century and carrying on through,
well, 1987. These are blood, genes stuff, sperm karotypes, and so on,
and it's still a pretty good summation of what's gone on on that subject.
