Question about evolution, genetic bottlenecks, and inbreeding

Thread moved here from the Proposed New Topics forum.

When I promoted this topic, my vision was that it was intended to discuss the "what ifs" of a very small species population. This could possibly but not necessarily be as small as only one male and one female. This could be from either the physical isolation of a small group away from the rest of the species, or the literal only the two of the species left on Earth.The Biblical parallel would be the "what if" the human species would have been just Adam and Eve. What would be the genetic chain of events of the ancestors of Adam and Eve be like?Or something like that.Adminnemooseus
