Hints of an early exodus of modern humans from Africa may have been detected in living humans.

People outside Africa overwhelmingly trace their descent to a group that left the continent 60,000 years ago.

Now, analysis of nearly 500 human genomes appears to have turned up the weak signal of an earlier migration.

But the results suggest this early wave of Homo sapiens all but vanished, so it does not drastically alter prevailing theories of our origins.

And two separate studies in the academic journal Nature failed to find the signal of a later movement.

Writing in Nature , Luca Pagani, Mait Metspalu and colleagues describe hints of this pioneer group in their analysis of DNA in people from the Oceanian nation of Papua New Guinea.

The researchers examining the DNA in Papua New Guinea found the traces of the earlier migration by subtracting the DNA from the more recent migration out of Africa 60,000 years ago and the DNA from the Denisovans.

  You will note that I've not indicated that any subspecies of man is in any way inferior to another subspecies. I've merely noted that there are differences

  You're correct.

  The thing is that some people with an ax to grind take a similar strategy or go into the "I'm just asking [disingenuous] questions" strategy. This is why some people will jump on comments like this with irrational ferver because they assume the parent was disingenuous (not a bad assumption for this topic) and they "know" that it is just a lead-in to the typical racist shit.

  Unfortunately, the community of this site (or anywhere, really) are unable to have productive discussions on this kind of topic.
