So I have
Just a couple questions. Do all negroid people fall under the E3 clad, do Ethiopians fall under this clade as well, and What clade would North african Arabs and regular Arabs fall under?
There are even older Haplogroups such as A and B (red and blue on the map above) which predate Out-of-Africa and which are parent to the E Haplogroup.
E Haplogroup has 3 related Branches, E1, E2 and E3. E1 and E2 are found only in Africa. E3 is most common and in turn hs 2 sub-clades which are defined by a specific Y chromosome mutation called P2. This is a genetic signature effectively. Anyone who is Pn2 E3a or E3b is therefore a direct decendant of the common male ancestor. Somali, Zulu, Tutsi and Hutu and Taureg for example are all related substantially to each other, and they are not related to Europeans. Europeans migrated out of Africa before the PN2 transition. Consequently, E3 Haplotype did not reach Europe for 20,000 years after its African origin.
This exposes the fallacy of applying a European race catagory, 'caucasian' or whatever to E3 Black Africans which is completely ridiculous and defies the logic of of genetics and ancestry.
You can also see in the map above the intermixture of West Asian haplotype J (the Arabs) and East African E3b in both North Africa AND West Asia. [green and orange]
Whereas E3b spread from East Africa into the middle east along with the Neolithic [the beginnings of agriculture], J spread into Africa primarily as a result of the Arab/Islamic expansion.
"Ancient Egypt" would therefore have been primarily E3 (a and b), and not J. And European lineages penetrate the delta region primarily from the Ptolemic and post Pharoanic times.
One more point: many Nilo Saharan's are predominently E3a. The Tutsi migrated into Rwanda from the North East and are likely Nilotic (ethnically).
Black African phenotype - basically broad headed vs. longheaded, has little to do with E3a vs. E3b and more to do with adaptation to dry vs. humid climate, and since populations migrate, this issue is complicated and requires tracing population history.
