How are genetic markers dated? What I mean is, when genetic markers are used to track population movements throughout human history like this one, National Geographic - 404How are the dates associated with the various populations arrived at?

Thanks for the reply, do you know offhand of any specific examples of where mutation rates can be directly measured?

awesome

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.Edited by Itinerant Lurker, : No reason given.Edited by Itinerant Lurker, : No reason given.
