Within extant African populations, both linguistic (Greenberg
1963) and genetic (Hiernaux
1975; Excoffier et al.
1987; Cavalli-Sforza et al.
1994, pp. 169–171) evidence indicates that most sub-Saharan populations are more closely related to each other, whereas Pygmy, Khoisan, and eastern African populations are the most differentiated.
Paradoxically, genetic comparisons of Khoisan and Ethiopian populations show both polarity and affinity with respect to one another. This has been shown by the principal-components (PC) analysis of 79 classical protein polymorphisms (Cavalli-Sforza et al. 1993, 1994, p. 191). Although the second PC indicates that the Ethiopian and Khoisan populations are the most divergent, the third PC shows a close relationship. Although intermediary Bantu-speaking populations currently separate these two groups geographically, archeological findings suggest that the Khoisan territory once extended above the equator, to present-day southern Ethiopia and Sudan (Nurse et al. 1985, p. 105).
In a previous study (Passarino et al.
1998), the genetic structure of the Ethiopian population was investigated using mtDNA and some nonrecombinant Y-chromosome (NRY) markers previously studied in the Khoisan (Soodyall and Jenkins
1992; Spurdle and Jenkins
1992). These markers, because of their uniparental inheritance and lack of recombination, are particularly useful for inferring the history of populations through female and male lineages separately.
Although the mtDNA did not reveal a particular relationship between Ethiopians and the Khoisan, affinities were suggested by Y-chromosome analyses. The YAP−/49a,f haplotype 26 (A2C0D0F0I1) combination appeared to be typical of these two groups (with a frequency of ∼7% in the Ethiopians and 10%–15% in the Khoisan; for the Khoisan frequency, see the discussion by Passarino et al. [1998]). With the exception of some Jewish subjects, particularly Ethiopian Jews (Ritte et al.
1993; Santachiara-Benerecetti et al.
1993), the 49a,f haplotype 26 is absent or extremely rare in all surveyed populations (found only by Torroni et al. [
1990] and Persichetti et al. [
1992]). However, because of the variability of the complex 49a,f system, a polyphyletic origin for haplotype 26 could not be excluded. A later combined study of seven biallelic markers and four microsatellites showed that the Ethiopians and Khoisan shared the “archaic” haplotype 1A (Hammer et al.
1998), defined by the marker SRY10831 A→G (Whitfield et al.
1995), but that they did not share the microsatellite variants (Scozzari et al.
1999). Most recently, a great number of Y-chromosome biallelic markers have become available (Underhill et al.
1997,
2000,
2001; Hammer et al.
2001). These markers, because of their very low mutability, have most likely arisen only once during human evolution, thus allowing a clear-cut definition of the worldwide Y-chromosome genealogy (Underhill et al.
2001).

YAP /49a,f haplotype 26(S18) is common to both Ethiopians and the Khoisan:

"The association between YAP /49a,f haplotype 26(S18) is interesting in several respects. First, four of the five Ethiopians in this survey who had the 49a,f hap-lotype 26 were also YAP. Although 49a,f haplotype-26 Y chromosomes were observed to be common in the Ethiopian Jews (Ritte et al. 1993
a), the YAP element was not examined in this group. Second, with the exception of Ethiopians and Khoisan, this haplotype is very rare in nearly all surveyed populations. Finally, the Tsumkwe San, which show a high frequency of haplotype 26 ,were also analyzed for the YAP element (Spurdleet al. 1994), but the association YAP/haplotype 26 was not reported. However, the frequencies of the two markers (30% haplotype 26 and 11% YAP) make it possible to deduce that at least two-thirds of the 49a,f haplotype26 of this group should be YAP.
. We speculate that the YAP /49a,f haplotype 26 combination represents an African characteristic preceding the Bantu expansion and indicates reciprocal affinity between Ethiopians and Khoisan. If one excludes this possible specific element of affinity, these two groups seem to share only a generic dissimilarity with Niger-Congo populations,with regard to Y-chromosome haplotypes.
