So the question is how large of population does one need to attempt to represent all the genome diversity that exist in the human population. And when you look to include blood types, bone differences, immunity, digestive and endocrine enzymes and more, you need about 10,000 humans. No group much smaller than that can represent the diversity in the human genome. (By comparison Chimpanzee's need closer to 100,000.) So that means the Ark was way short handed. Or successful mutations are much easier to appear in the genome and so no handicap to quick macro evolution well faster than any biologist would imagine possible.
