Ignore him. He barely understands population genetics, nevermind history. Answering his comments is dignifying them and wasting time better spent discussing more productive things with other, actually knowledgeable people.<quoted text>
I hope that you have learned that the world cant be divided in black vs white or european vs african.
Just look at his claim that Hassan et al.(2008) associate E1b1b1a1 (E-V12) with Nubians. This is a blatant lie. In reality, Hassan and his colleagues state in no uncertain terms that the presence of all E1b1b1a (E-M78) sub-clades in Sudan is due to admixture with migrants from North Africa (i.e. Hamites):
"The analysis of M78 subclades among Sudanese suggests that two subclades, E-V12 and E-V22, which are very common in northern African (Cruciani et al., 2007), might have been brought to Sudan from North Africa after the progressive desertification of the Sahara around 6,000–8,000 years ago. Sudden climate change might have forced several Neolithic cultures/people to shift northwards to the Mediterranean and southwards to the Sahel and Nile Valley"
Cruciani et al.(2007) likewise clearly indicate that E1b1b1a (E-M78) itself originated in Northeastern Africa (which they define in their study as Egypt and Libya):
"the peripheral geographic distribution of the most derived subhaplogroups with respect to northeastern Africa, as well as the results of quantitative analysis of UEP and microsatellite diversity are strongly suggestive of a northeastern rather than an eastern African origin of E-M78. Northeastern Africa thus seems to be the place from where E-M78 chromosomes started to disperse to other African regions and outside Africa."
Besides experiencing admixture from living near Egypt, Hassan et al.(2008) also state that, among the Nilo-Saharan-speaking groups, the Masalit in Western Sudan have significant frequencies of the Egyptian E-M78 subclades because of a recent population bottleneck:
"The Masalit possesses by far the highest frequency of the E-M78 and of the E-V32 haplogroup, suggesting either a recent bottleneck in the population or a proximity to the origin of the haplogroup."
Because this Afrocentrist character probably has no idea what that the term "population bottleneck" means, he now believes the Egyptians are really Nubians! LOL Perhaps you should explain to him that a population bottleneck means that something likely happened to the ancestors of the Nilo-Saharan groups in Western Sudan (either in the form of famine, drought, war, disease or natural disaster) that killed off a bunch of said peoples.
That means that the various haplogroups present amongst their descendants today, such as the Fur, are just a small fraction of what they were in the past. In other words, the modern frequencies of E1b1b1a (E-M78) sub-clades in these same populations are unrepresentative of and were proportionately way lower in the past (prior to that devastating bottleneck event) than they are today. Not to mention that even back then -- which wasn't that long ago, according to the authors -- these E-M78 sub-clades were introduced by North Africans. They were never native to these or any other Nilo-Saharan groups.
