They have a good summary on the background of the Indian-African links in their approach.
1) African individuals of the CT haplogroup harboring the central profile of the Indian/African Y-STR network (Fig. S7) crossed over into Asia around 70 Kya.
2) Approximately 65 Kya, at some point along the southern coastal route, the CF haplogroup arose on this Y-STR background and its members migrated eastward into the southern tip of the Indian sub-continent.
3) F may have originated from CF on this Y-STR background somewhere between southern and western India.
4) In turn, the GHIJK macrohaplogroup emerged from F. Population growth and geographical dispersion may have caused a rapid expansion of Y-STR profiles. If the original Y-STR haplotype was carried over into the GHIJK pool, it was soon swamped by descendant haplotypes via rapid genetic diversification.
5) In contrast, the basal F*, associated with these South Asian tribal communities, experienced reduced rates of population growth and thus, a substantially reduced Y-STR diversity. In this setting, it is conceivable that the original Y-STR haplotype was retained at polymorphic frequencies.
