[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by beyoku: [qb] Those that live in the tropic zone unaffected by migrants from the North do have Tropical limbs. They also typically have dark skin. This is not only true for India but POSSIBLY Aboriginal populations in the Arabian peninsula and definitely populations in the South Pacific as well.[/qb][/QUOTE]Correct. Tropical adaptation is not a phenomenon confined to Africans only. Limb proportion adaptation is known in biology as Allen's Rule which state that endothermic that is warm-blooded animals have shorter limbs in adaptation to cold climate while they have longer limbs in adaptation to hot climate. Longer limbs means greater dissipation of heat while shorter limbs mean conservation of heat. Of course it's not just a matter of hot and cold but in between as well which is why populations adapted to temperate climate display intermediate type limb proportions. What's interesting is that there was a study presented before showing limb proportions of different populations and Indians, particularly northern Indians displayed such intermediate limb lengths. This could mean that such Indians have ancestors from more temperate areas. By the way, there are exceptions to the Allen's Rule, namely pedomorphic reduction which I will discuss sometime in the future. [QUOTE][qb]These Indians though, regardless of their body type had nothing to do with the peopling of the Nile Valley or Sahara. So what is your point in bringing them up? [/qb][/QUOTE]The lyinass knows this she just wants to get attention away from Africa as per her anti-African sentiments. [/QB][/QUOTE]
