	Using a Medline keyword search for "cheetah and (population or
evolution)" netted me a baker's dozen of articles published in the last
ten years. That's the _entire_ literature on the species. The data seem
to support a substantial bottlenecking around 10K years ago, at the end
of the Pleistocene, when many largish land mammals went extinct all around
the world. Note this coincides with the start of the current interglacial
period. I suspect it's a hard call whether aboriginal human hunting can be
fully discounted as causative of the cheetah bottleneck, just as I suspect
it's a hard call whether the extinction of woolly mammoth was not human-

	Spend an afternoon in the library & get back to us, OK? :)
