When? H has entered Europe about 5KYa as most aDNA studies have showed.

In other words maternally, Tuaregs and Germans are of the same stock, Germans more related maternally to Tuareg than Tuareg are related maternally to Sub Saharan Africans. This African component of modern Europeans relatively quite recent " 5 kya" [/qb][/QUOTE]I am not sure if this is on xyyman neceserally, Frigi et al. speaks on this as well. [QUOTE] [b]Haplogroup L1b roots deeply in the human mtDNA phylogeny and has the characteristic motif 16126, 16187, 16189, 16223, 16264, 16270, 116278, 16311. [/b] [...] Our results also point to a less ancient western African gene flow to Tunisia involving haplogroups L2a and L3b. Thus the sub-Saharan contribution to northern Africa starting from the east would have taken place before the Neolithic. The western African contribution to North Africa should have occurred before the Sahara’s formation (15,000 BP). [...] The dates for subhaplogroups H1 and H3 (13,000 and 10,000 years, respectively) in Iberian and North African populations allow for this possibility. Kefi et al.’s (2005) data on ancient DNA could be viewed as being in agreement with such a presence in North Africa in ancient times (about 15,000–6,000 years ago) and with the fact that the North African populations are considered by most scholars as having their closest relations with European and Asian populations (Cherni et al. 2008; Ennafaa et al. 2009; Kefi et al. 2005; Rando et al. 1998). How- ever, considering the general understanding nowadays that human settlement of the rest of the world emerged from eastern northern Africa less than 50,000 years ago, a better explanation of these haplogroups might be that their frequencies re- flect the original modern human population of these parts of Africa as much as or more than intrusions from outside the continent. The ways that gene frequencies may increase or decrease based on adaptive selection, gene flow, and/or social processes is under study and would benefit from the results of studies on autosomal and Y-chromosome markers.
