I feel I would have been 5'8 in Somalia but since I was well fed growing up I'm 6'0. I bet many Somalis don't reach there maximum height potential because of poverty. Although, I suppose they get to have higher testosterones due to whole food diet.The tallest I've seen are MJs, from DDSi to be precise, and not mixed with OG or Dhulos either.
My family is tall, men and women alike, and I don't just mean my nuclear family.
I assume there could be a factor where coastal Puntites are affected by marrying those Semites such as Arab Salah over time. Perhaps similarly with other coastal Somalis. We need real studies though.
