I clicked on the link at the bottom of the page.
Archaic hominin introgression in Africa.

So it's not really a human, but a hominin, mixed in with modern Sub-Saharan Africans?
Maybe this should be in the medical genetics section?

In some people, the gene that codes for MUC7 holds six copies of genetic instructions that direct the body to build parts of the corresponding protein. In other people, the gene harbors only five sets of these instructions (known as tandem repeats).

Prior studies by other researchers found that the five-copy version of the gene protected against asthma, but Gokcumen and Ruhl did not see this association when they ran a more detailed analysis.
