That pretty much kills the "all living things come from a single common ancestor" theory doesn't it?

All human mitochondria come from a single common ancestor. Do you think this means that the human race required only one individual to survive?

They did cover the birds and the bees in whatever school you attended, right?

Do you remember this?

Yes, most evolutionary biologists believe all life has a common ancestor, although because that ancestor was a prokaryote, and prokaryotes exchange genes with each other, it might be more correct to speak of a population of common ancestors.

Would classify a prokaryote as a bird or a bee?
