Although the region, a stretch of DNA on the 17th chromosome, occurs in people of all countries, it is much more common in Europeans, as if its effect is set off by something in the European environment. A further unusual property is that the DNA region has a much more ancient lineage than most human genes; the researchers suggest, as one possible explanation, that it could have been inserted into the human genome through interbreeding with one of the archaic human lineages that developed in parallel with that of modern humans.

I tend to believe that it was in the DNA all along. That would explain its "much more ancient lineage".
The article was interesting, but it did not prove that information is added, just rearranged.

That's right, it was an inversion, a type of "rearrangement."

IOW a beneficial mutation and one that did not diminish the information.

That's how it works. The issue was your assumption that mutations cause a loss of information.

This was an example of one that doesn't.
