quote of the moment

"according to one calculation*, everyone alive today descends from a population of fewer than 14,000 breeding individuals from sub-saharan africa, and the entire population that gave rise to all non-africans was probably fewer than 3,000 people."

That may be true, but presumably all humans are descended from a single living thing at some point in the past, and in fact all living things are descended from a single ancestor in the far past.

It's not clear to me what the relevance of a more-recent population bottleneck is.
