The only thing I'd say is that we have a higher proportion of people with soft or even straight hair than the countries I've mentioned. From what I've seen, it's usually the darkest ones who have the straightest hair. Cacs got nothing to do with our features.
I notice while in Ethiopia the darkest people had the straightist/waviest hair.
But I think North Sudanese and indigenous Berbers edges you guys out when it comes to softest hair. But yeah yall features have nothing to do with Eurasians(non-Africans).
"....inhabitants of East Africa right on the equator have appreciably longer, narrower, and higher noses than people the Congo at the same latitude. A former generation of anthropologists used to explain this paradox by invoking an invasion by an itinerant "white" population from the Mediterranean area, although this solution raised more problems than it solved since the East Africans in question include some of the blackest people in the world with characteristically wooly hair and a body build unique among the world's populations for its extreme linearity and height.... The relatively long noses of East Africa become explicable then when one realizes that much of the area is extremely dry for parts of the year." (C. Loring Brace, "Nonracial Approach Towards Human Diversity,"

" These studies suggest a recent and primary subdivision between African and non-African populations, high levels of divergence among African populations, and a recent shared common ancestry of non-African populations, from a population originating in Africa. The intermediate position, between African and non-African populations, that the Ethiopian Jews and Somalis occupy in the PCA plot also has been observed in other genetic studies (Ritte et al. 1993; Passarino et al. 1998) and could be due either to shared common ancestry or to recent gene flow.
The fact that the Ethiopians and Somalis have a subset of the sub-Saharan African haplotype diversity and that the non-African populations have a subset of the diversity present in Ethiopians and Somalis makes simple-admixture models less likely; rather, these observations support the hypothesis proposed by other nuclear-genetic studies (Tishkoff et al. 1996a, 1998a, 1998b; Kidd et al. 1998) that populations in northeastern Africa may have diverged from those in the rest of sub-Saharan Africa early in the history of modern African populations and that a subset of this northeastern-African population migrated out of Africa and populated the rest of the globe. These conclusions are supported by recent mtDNA analysis (Quintana-Murci et al. 1999)."
