Afro's

Firstly i mean people as a whole wen i say we rather than me myself (straight haired).Anyway, the question is simple: why do some people have afros?Might seem a bit of a trivial question, 'because their parents do' etc...But what im interested in is - what has affected different parts of the world, to make people have thick, very tightly curled, dry hair?Is it...climate? something to do with the humidity, or temperate of certain areas of the world?Apparently some people in southern asia also have afro's...Obviously the word implies its something to do with africa, but not all africans have afros...and in similar climates further east people have thick, long, straight hairWhat d'u think?

Tightly coiled hair is typically described as being an evolutionary adaptation to the warm, tropical climates of sub-Saharan Africa and Melanesia (although it does not exist in tropical regions such as India or indigenous South America and thus likely evolved for a different original purpose). Some hold that tightly coiled hair may allow for greater cooling because sweat is able to remain on the scalp.[1] Furthermore it has been asserted that, when the sun is directly overhead, the top surface of the hair heats up while leaving a barrier of cooler air between the scalp and the top surface of the hair. This barrier of cooler air assists in cooling the brain. This effect is most prominent in people with 'frizzy' (Afro-textured) hairthere u go. thats only for black people. if anyone else from other races have afros its because they got niggers in their family somewhere down the line

Was abaaat to post summit similar... it's all to do with climate and the fact that it's used as a coolin method

Hmm that doesnt provide much answers.http://en.wikipedia.org/wiki/Afro_textured_hair big page on its development, alot more complicated than i imagined for some reason.

For anyone whos (lazy, but) interested:"The trait may have reached high frequency in order to compensate for the gradual process in which relatively pale hominid (pre-human) skin was being exposed to the African equatorial sun as it lost its protective fur (as indicated by Iyengar 1998--also see Rogers et al 2004). Once dark skin evolved however, the Afro-hair texture was no longer essential for protection. Nevertheless, it was not a liability either (by contrast, it was indeed a liability for those who migrated to northern Eurasia--see hair texture). Therefore, there was no pressure within Africa to re-evolve straight hair""Afro-hair is, in this sense, most likely a reminder/remnant of a crucial time in hominid evolutionary history (ie when humans became hairless to enable persperation). Also, while this unique texture may arguably provide additional comfort in hot areas, it did not initially evovle simply for this purpose. Furthermore, it should be emphasized that Afro-hair texture is, by far, not essential to survival at the equator given the presence of dark skin. Thus, dark skinned straight haired groups are able to survive in sunlight-rich regions without tightly coiled (Afro) hair texture."

Obviously the word implies its something to do with africa, but not all africans have afros...and in similar climates further east people have thick, long, straight hairWhat d'u think?
Swear all the Africans who aren't black migrated there or were bought there by force? So originally all Africans do have afros?
