when you say "pure", I assume you're contrasting the situation where a
population is defined by long-term *in situ* adaptation and some
degree of breeding isolation from surrounding poulations, as oppossed
to hybridization between two or more such pre-existing groups. I
haven't seen convincing evidence one way or the other, though I lean
towards the former. It appear to be the more parsimonious explanation.

Actually, there are significant geographical barriers between the
homelands of the IE and HS populations. The black sea, the caspian,
and the highlands of anatolia, the caucasus, and iran would provide
suffient isolation to inhibit genetic transfer; in addition, the two
areas are subject to very different kinds of selection pressures.
Linguistic affinity between HS and IE languages is an interesting
connection, but I have a hard time relating it to the evolution of
either language or populations. Any suggestions?

People move, genes move, but local variation in selection criteria
plus geographic barriers will maintain steps in the cline. Those steps
are the logical place to differentiate subpopulations, and all the
groups you list above precisely match the conditions for existing as a
My best guess is that the proto-IE people occupied the great swath of
steppe lands from the ukraine east to lake balkash, descending
directly from the ice-age big game hunters whose mammoth-tusk shelters
are so well known. They probably had pretty close affinity to the more
westerly europeans as well; the hungarian and north german plains are
The sheer size of this ecosystem creates some interesting dynamics for
hunter-gather residents. Some of the modern characteristics of IE
societies may still be tracable to those conditions.

What did you have in mind? I think the eurasian steppe remained as a
single ecumene throughout the transition to this interglacial.

Hmm, the 5-fold division into bushmen, pygmy, negro, nilo-sudanese,
and abyssinian looks pretty clear-cut to me; for the purpose of
taxonomic consistancy with a distinction such as
ural-altaic/dravidian/indo-european it may be necessary to further
subdivide the subsaharan races, but it's a good start.

Right. This is a key factor which is often overlooked in studies of
human evolution. Glacial/interglacial cycles have followed one another
during the last few million years of human evolution with a
periodicity of abouut 100,000 years. Since h. erectus left africa
about 1 million years ago, the old world hominid population has gone
through about 10 cycles of glaciation. Moving to greener pastures has
a long history for humans, and one of the aspects of culture which I
consider to be of supreme importance is _making a virtue of
necessity_. Go west, young man.

Don't lump the pygmies and bushmen together; they are very distinct
peoples. The pygmies are adapted to the rain forest environment,
whereas the bushmen lived in more open country. The genetic distance
between them might be greater than that between swede and han.

Actually, domesticated animals are not necessary to create the desert.
They can enlarge it, but the cycle of desert/savanna continues
regardless. Look at it from the standpoint of a 100,000 year cycle; a
lag of a few thousand years is insignificant.
See william calvin's web page for a wonderful selection of readings
on human evolution, particularly on the sahara pump.
