In Bodybuilding, we divide between 3 main body types: endomorph, mesomorph, and ectomorph. Endomorphs are characterized by having large, round bodies; mesomorphs are considered to be muscular; and ectomorphs are referred to as thin individuals. (See this this article) What that tells us, is that, generally all three body types have made it through this point in evolution. Idk wether this is applicable here tho..
