Admixture results:
Tigray/Amhara/Afar are Ethiopian ethnic groups
Well, sure. But it’s not like Ethiopians are unique in this regard. Africa is holds the vast majority of humanity’s genetic diversity.
The Bantu expansion was a big deal for Central Africa and crowded out local indigenous groups, but it definitely didn’t turn the entire continent into a sea of generic Bantu people except for Ethiopia.
Those indigenous groups are often still around, as are other a number of groups of African origin that are as different from each other as a Swede is different than a Thai. Add in continuous contact with the Middle East and the Mediterranean (and things like Madagascar’s settlement by people from Borneo), and you get a hugely diverse continent.
How about specifying which previous answers are nonsense?
And “they are different” is not an answer to “why are they different”.
It is perhaps worth knowing the posteralso believes it is “PC” to tell him his worries that a certain car type can make him look gay are very silly to be polite.
the quality of the intervention’s logic and information can be understood better.
There’s not necessarily a direct correlation between the amount of outward differences between two populations and the amount of genetic variation causing it. Also, doing this ‘by eye’ may be very subjective - like trying to compare accents - your own perception significantly biases your subjective measurement of ‘difference’
Right. The question in the OP is very similar to asking why Swedes don’t look the same as Greeks. They’re all Europeans, right?
DNA haplogroup research is quite interesting, but it’s also interesting that haplogroups don’t really map up well to traditional concepts of “race”. For example, my own y-haplogroup, R1b, is is common in Spain, France, and the British Isles, but is also quite common in Cameroon! By contrast, haplogroup E, which is mostly found in Africa, was (as north-African subtype E1b1b) possessed by Lyndon B. Johnson, Napoleon, the Wright Brothers, and a well-known racist German dictator. It’s quite possible that the paternal ancestor of the Wright brothers entered what is now England as a Roman soldier of Berber or Egyptian background who was himself far more closely related to cousins in sub-Saharan Africa than he was, say, to a Viking.

The thing is, even tho most Europeans are diverse in looks, they still look somewhat related. Not to mention usually in Europe, theres a gradual change in phenotype as you move from one location to another. Whilst in East Africa,the change is very drastic as you saw with the kenyan-Ethiopian comparison. These people are only seperated by a border yet they look completely different.
Oromo Ethiopian
Kenyan Luo
Compare that to a German and A french
Well, Europe doesn’t have anywhere near the genetic diversity found in Africa. It’s a seriously diverse place. Your average American just doesn’t see a lot of it, probably because we don’t meet that many Africans from various parts of the continent.
It’s not really a bright line between Ethiopia and everywhere else. Ethiopia itself is very diverse, and other areas near Ethiopia are also diverse. And that level of diversity is common. In the small town I lived in in Cameroon, maybe a dozen ethnic groups with origins from Senegal to Sudan lived together.
