In South Africa, Australia, South America, New Zealand, the 'native' (ie. non-European) peoples are granted near-mythical status, on the basis that they arrived tens of thousands of years before Europeans.

But if this kind of genetic evidence indicates that there were actually waves of migration, conquest and assimilation, that non-European migration waves were relatively recent, and that Europeans are just the most recent one, then the status of Europeans as 'bad guys' and everyone else as 'good guys' falls flat.
