Anyone have a link to the theory there was man somewhere in the

there's one man from the middle east from 4,000 years ago or something that 99.9% every person is related to, there is also a woman from like 6,000 years ago that almost everyone is related too as well

Is there anything you can give to back this up for me? Forgive my ignorance.

I've also read theories at one stage in human development (during the last ice age) human kind was cut down to one singular cave, somewhere in Russia (I think) and one singular tribe.

Since you get your X from your mom, and your Y from your dad, you can trace the X and Y through history back to two individuals. That's not to say they ever met each other though. It just so happens their chromosomal lineages survived.

Not that drastic, but there was a bottleneck effect that may have brought us down to 10,000 individuals. If it had been that drastic we likely wouldn't have lasted, just by removing that much genetic diversity.

It's not too much of a stretch to say a man who lived in a port was a fisherman by trade, it's also besides the point.

This one? It's about a mathematical simulation of human migration and reproduction. I don't know where you get Taiwan from.

To add, this paper was about shared common ancestors, not proportion of DNA, so it might not be what you were thinking about.
