What I was explained was how they kept reproducing without 100% incest

  There an amazing number of coincidences that have led to human life existing. I only know of the anthropic principle greatest hits from physics including The Moon, plate tectonics, distance from sun, etc but I assume there are more from the natural world of evolution. So I wouldn’t be surprised to hear that the bottleneck population also wiped their bottoms with leaves from a tree that grows only in natural uranium ore, thereby artificially boosting their genetic diversity as well as putting pressure on them to reproduce frequently and often before they reach their radiologically reduced life expectancy of 25.

    > amazing number of coincidences All of this in light of the very literal form of survivorship bias. Try a few billion or trillion planets to get the conditions JUST right and there will probably be at least one getting it right. Inhabited by folks who wonder why it was their planet that had everything going for it.

        "anthropic principle" = Survivor Bias. Never liked the anthropic arguments. Even back with Leibniz, arguing this is the 'best of all possible worlds' because it is the one we exist in that god provided. It's circular, or calls for some mysticism or parallel universes.

  Hypothetically speaking, and I'm putting an emphasis on the "hypothetical" part, you could have two individuals starting a new population of arbitrary size, without ill-effects of inbreeding. There is only one requirement. And one caveat. The requirement is that both individuals need to be free of genetic defects in their alleles, so that no matter how many generations down you go you never end up with two defective alleles in the same descendant. That is impossible in practice. Eventually you would get some diversity from random mutation and at that point you would be back to "normal" state of affairs. The caveat is disease resistance. All of their descendants would have the same immune system. If one gets sick, they all do. Any infection will spread like wildfire, if it spreads. And nothing short of total quarantine would stop it.

  >"reproducing without 100% incest" This seems like such a contradiction with Christians. They just do lot of hand-waving and ignore it. Then went and read the Bible and what did I find, there were other people at the time of Adam and Eve. The Bible actually discusses the other humans that were living in other lands At The Same Time As Adam and Eve. Totally blown away. So then, why do Christians today completely believe that God Created Adam And Even and they were the very first humans and thus Evolution is Wrong. How can you argue that Evolution is wrong, because of Adam and Eve, when right in the Bible it discusses the other groups of humans?

    I think some of it is conflict from the evolution of monotheism from "the true god, the only one you should worship" to "the only god".
