Population genetics question
How are genetic markers dated? What I mean is, when genetic markers are used to track population movements throughout human history like this one,

How are the dates associated with the various populations arrived at?

Keep on keepin on
Following the logic of the argument that Adam and Eve were created with perfect genes 6,500 years ago I'm wondering if that doesn't necessarily predict that we should be able to take a look at dna from people three thousand years ago and see a pretty huge difference between it and our dna today in that it should be "half as perfect". Anyone know of an example of this? Or does this pretty much not make sense at all.
​
Note: By "this" I'm referring to what this argument would predict, not the argument itself which is, of course, absolutely retarded.
