Phi for All Posted September 2, 2019 Share Posted September 2, 2019 I read somewhere once that, besides the obvious heritable traits, the overall shape of the nose is dictated by ancestral environment, factoring in things like temp/humidity, dust/pollen counts, and local vegetation.

Curious layman Posted September 2, 2019 Share Posted September 2, 2019 (edited) It's what JP Morgan had (Rhinophyma, commonly due to untreated Rosacea) https://en.m.wikipedia.org/wiki/Rosacea https://en.m.wikipedia.org/Rhinophyma Edited September 2, 2019 by Curious layman Link to comment Share on other sites More sharing options...
mistermack Posted September 16, 2019 Share Posted September 16, 2019 My own guess would be that it's to do with Neanderthal dna. The last stronghold of the Neanderthals was around Southern Europe/North Africa, and that's where the pointy noses seem to be historically clustered. Sub Saharan Africans don't have any Neanderthal dna, and usually have flat noses. Eskimos and Inuit have flat noses, so if it's an adaptation to the cold, it takes a long time to happen. Of course, that's just a guess, I'd give it no more than ten percent chance of being right. Link to comment Share on other sites More sharing options...

"usually" And yet, there are so many different groups across Sub Saharan Africa and many of their noses aren't that flat and the genetic variety is so widespread across the continent, that broad and sweeping generalisations like that are highly amusing...

mistermack Posted October 9, 2019 Share Posted October 9, 2019 It must be great to be so easily amused. But also, a little bit sad. Link to comment Share on other sites More sharing options...
