Third gene flow?

[thetick]

I noticed an interesting statement when looking at Chris Stringer Wikipedia page. Note it's only in the German version, not sure why the English version is missing this picture/details.

See the area I circled in red:

1428

From Google Translate:

"Right outer points stringers that some genetic abnormalities have been found in Africa that seem to point to a third gene flow from an as yet unknown pre-human population of anatomically modern humans

http://de.wikipedia.org/wiki/Chris_Stringer

References Michael F. Hammer et al.: Genetic evidence for archaic admixture in Africa. In: . PNAS band 108, No. 37, 2011, p 15123-15128, doi: 10.1073/pnas.1109300108


So what evidence is there for this third gene flow? Is this another human ancestor or just an isolated Homo erectus or heidelbergensis population? Is it a reference to the Sima de los Huesos findings? Any ideas?

Perhaps "Iwo Eleru ... there is evidence of an input of archaic DNA into some modern African populations as recently as 35,000 years ago."
