On the very enlightening mystery of e-v32 vs e-v1515

[Midas]

I waa looking at e-v32 distribution in different pouplations and then I got curious and decided to look uo what e haplogroups were extremely common among northern Ethiopian/ertrieans and then that led me down a rabid hole to look at other groups like the afar/saho. Basically the distribution of these different haplogroups among the pouplations of northeast Africa make no sense.

This is the distribution of e-v32 and e-v12 . With red being e-v32 and blue being e-v12. 75% of the garre and southern eygptians are e-v12 . 60% of the fur and masslit which is the western Sudan groups i circled have e-v32 . The blue in somalia is garre who are the most basal somali clans a
have 75% e-v12.

Here is the distribution of e-v1515 which is the most dominant among northern Ethiopian/Eritreans and the most ominant haplogroups of modern southern cushites in tanzania.

for those of you who are not familiar with this stuff. E-v1515 is an extremely basal clade. 80% of Somalis,southern eygptians and beja/massalit/fur are e-v12 and its subclades . E-v12 is decdsended from e-m78. Whereas e-v1515 is not descended from e-m78. The most recent haplogroup that the habesha share with the rest of us is e-m35 and the tmrca for that is 25,000 years ago.

Now this begs the question how do people from southern eygpt/somalia/northern Sudan all share e-v12 ( a haplogroups that formed 12,000 years ago) which is a sub sub clade of em-78. But somehow our southern cushtic neighbors who are pastoralists like us share their haplogroup not with somalis/sudanese/eygptians. But share the far more ancient haplogroup e-v1515 ( which formed 19,000 years ago) with habeshas.

The common rule in genetics is that farmer pouplations are generally more genetically diverse than pastoralist pouplations. This seems to apply to the habesha vs somalis in that habesha seem to have a lot more archaic e haplogroups than us. But suddenly when it comes to eygptians and Sudanese they all seem to have e-v12 as their main e haplogroup and a few others descended from e-m78. You can somehow find far more e haplogroups in somalis than in eygptians and Sudanese.

But when you get to the much more recent haplogroups from later migrations into eygpt from the middle east you Suddenly have all of these haplogroups persevered.
