Mc Donald's isn't doing so great. The lines are getting a lot shorter.
Short of testing DNA and wearing a tag around your neck with you genetic vitals it pretty hard to determine origins. A couple of things compound the problem. There was a severe bottle neck in the human population around 72,000 years ago. This was likely caused by the eruption of the super volcano Toba in Indonesia. Humanity nearly went extinct so all of us come out of a pretty small gene pool. We are also finding out that early humans were a lot more mobile that we have thought and where ever they went they tended to leave genetic material. IR sex apparently isn't a recent innovation.
So I really don't care what anyone claims to be. Call yourself black, white, yellow, pale green I really don't care. However if we get naked I definitely want to see a pussy and I do prefer it to be original equipment.
