Big Bad Voodoo Posted August 17, 2013 Author #51 Share Posted August 17, 2013 why do you say escaped? Because if it was a good in Africa they wouldnt left it. Link to comment Share on other sites More sharing options...
Skep B Posted August 17, 2013 #52 Share Posted August 17, 2013 not necessarily. people move sometimes to suit their specific needs, they were lighter skinned with less melanin, so they'd want to go someplace with less sun intensity. i dont think its because africa is out and out bad, or any other place is good. its just what suited their needs Link to comment Share on other sites More sharing options...

DecoNoir Posted August 17, 2013 #55 Share Posted August 17, 2013 Because if it was a good in Africa they wouldnt left it. What? No, we migrated like any other species migrates, food. As the human population grew it saw fit to expand in order to support itself. And since we're talking about humans here I'd suppose a factor of "Hey guys, there's way more stuff that way!" had something to do with it. 1 Link to comment Share on other sites More sharing options...
Insanity Posted August 17, 2013 #56 Share Posted August 17, 2013 Insanity, So North Europeans, Slavics, Chinese were among first people who escaped from Africa? Lighter you are you are more adventures. Are you suggesting that they were the first to leave Africa because they have lighter skins? Irregardless as to when a population of humans may have first left Africa, the population remaining there would retain a darker skin as long as the levels of UV light required it. As humans moved away from the latitudes of higher levels of UV light, their skins would lighten. That is adaptation. Judging which group of humans may have first left Africa by skin color is not really a sound principle. Because if it was a good in Africa they wouldnt left it. Ofcourse they move for better lives. Species tend to spread out as long as there is access to space and they can adapt. Link to comment Share on other sites More sharing options...

Big Bad Voodoo Posted August 17, 2013 Author #62 Share Posted August 17, 2013 (edited) and maybe forgetting why white people get brown when in the sun... No I didnt. I just didnt know that evolution choose priority and evolve into one direction ignoring others variables. Lets protect humans from UV...who cares why they sweats more. I thought that nature have gentile flexible ways. Edited August 17, 2013 by Melo Link to comment Share on other sites More sharing options...

Grandpa Greenman Posted August 17, 2013 #75 Share Posted August 17, 2013 If you take animals of the same species cut them off from some of their fellow animals they will develop different traits over time due to mutations even if the environment is the same. Not all change is adaption to the environment, It can be caused by mate selection. Also humans adapt their surroundings more than adapting to their surroundings. We adapted to cold with fire and clothes rather than growing more hair. The separate populations over time may evolve distinctly different characteristics. If the geographical barriers are later removed, members of the two populations may be unable to successfully mate with each other, at which point, the genetically isolated groups have emerged as different species. Allopatric isolation is a key factor in speciation and a common process by which new species arise.[2] Adaptive radiation, as observed by Charles Darwin in Galapagos finches, is a consequence of allopatric speciation among island populations. http://en.wikipedia.org/wiki/Allopatric_speciation Link to comment Share on other sites More sharing options...
