Question for Dennis about population genetics

[pevaquark (Matthew Pevarnik)]

@nashenvi

Let me rephrase that to see if I understand. Imagine an original human pair living around 200,000 years ago with chromosome 1s given by (A,B) and (C,D). Each chromosome would differ from the others at around 1.8M b.p. If we assume that this pair gives rise to some N=10,000 population, then all the members of that population would have one of only 10 possible genotypes (A,A), (A,B), (A,C), (A,D), (B,B), (B,C), etc…

(note: I’m not a biologist- I keep prefacing these posts like this as they are highly technical)

So, earlier in this thread, @Swamidass showed a paper that literally showed there never could have been less than 29 people at any given time. And then the size of the human population needs to be much grater to retain the DRBJ polymorphisms.

A good study on this is by Fransico Ayala,

Human and Chimp Similarity

Continuing the discussion from Do Evolutionary Theory And Scripture Contradict Each Other?: While we won’t know what the chimp genome really looks like until more accurate research is done, I recently did a study of the chimp reads that have lower levels of human DNA contamination, and in this newer study the chimp DNA is only 85% similar to human at best, not 98%.
