The Checua people were not on that map.

Now they are.

The map is more complete for their inclusion, but it is also more complicated.

The assumption that the early population of the Colombian Altiplano could be predicted from what was known about other South American ancient populations has been shown to be wrong.

The early occupants of this particular high plateau developed, or arrived with, a genetic character distinct enough to be unmatched in any comparison population studied so far.

That is the scientific finding, stated plainly.
