I posted this article coz it was recent. The theory of human migration is not new itself, just the discovery/testing of this gene.
I just present information - I don't put any spin on it. It's up to the individual to assess the information as they sit fit to read further or ignore.
Posting information on the internet is not validating it. Academics, researchers and historians do that job.
Obviously the above poster knows all this info already - good for you. I didn't, and maybe someone else might not know it either.
It's as simple as that.
