Two people reproduced 7 billion people.

You'd say, or you know? Because what you want to believe, and what can actually be proven are two different things. You gotta do the math, if you're going to make claims like that.

I've done the math. Neither one of us knows what the actual rates have been over time, but I'll bet most people find 10% reasonable.

Now, I could continue here, adding that you're probably not taking into account the number of people who die in childbirth before reliable medical care, but that would just be foolish. It'd be foolish, because you still can't get a stable gene pool from the offspring of just two people to begin with. Start there, since it's the foundation of your premise. I refuse to take the rest of it on faith until the baseline can be established.

So don't take it on faith. Doesn't bother me.
