Degree of Sexual Dimorphism Between Populations

[The Journeyman]

Last semester in my anthropology class I was reading about mating habits among apes and how the degree of sexual dimorphism between males and females dictates the type of mating phenomenon. The less the degree of sexual dimorphism, the more monogamous the male is, and to the extreme of that, with an inverse sexual dimorphism, the more polyandrous. Species with a higher degree of sexual dimorphism tend to be polygamous.

Could there be biological differences within certain populations of the world that are naturally inclined to cultural practices such as polygamy, polyandry, etc?

[Agrippa]

Europids have a stronger sexual dimorphism than Mongoloids, Negrids vary, but usually they have a somewhat stronger dimorphism as well.

Among the racial types with the strongest sexual dimorphism worldwide are
among Europids:
- Gracilmediterranid
- Gracilindid

In Negrids:
- Kafrid (Bantuid)

Weak sexual dimorphism can be observed in people like the infantile Palaemongolids in South Eastern Asia.

Mongoloids





In Spain, to call "mongolo" to someone is... well, nothing good.
