   human races discussion .., black,asian, caucasian
  Hi..,All of this started with a talk i was having with a colegue of mine, where he defends that we human, all of us camefrom one single primate specie (which is the theory currently science has), while i say that i believe we all camefrom diferent primate species.Well, i believe there are 4 diferent races, caucasians, blacks, asians and native americans.Then each of these, even has more diferent sub-races.caucasians for example, in south europe they are shorter, darker skin, dark hair, dark eyes., in north europe they are much taller, blond hair, colored eyes.., and the diferences are not just in the outside looks , thecranial bone structure is also diferent.blacks, are also much diferent between them, many sub-species, mainly in the cranial bone structure.asians, same thing, many diferences here too, japanese are diferent than south chinese, which are diferent from indians,and so on and on.Some people advocate that the environment itself made the "looks" of the specie, and altough i agree with this,the theory of evolution has this very well suported by what happens in the galapago islands, in case of the humansthis doens't sound that it can work.evolution takes millions of years to happen.I allways learned in school that native americans are descendents of nomads that crossed the bering straight from russia to america. If that is so, they had significant transformations after making that cross., and also, braziliannatives are much diferent than north american natives, and this changes doens't happen in a couple of thousands of years.And then theres australia, there are humans in Australia for thousands of years, i can't believe they crossed the indic ocean in a boat and here we are..., and then after get there, what change in the environment could causethe human body to shrink to give origin to the pygmies ?Actually, i have no explanation on how they get there in the first place, the australian continent has been seperated from the asian continent for millions of years, much before the primates even take a step in the planet.So, where am i going with all this babbling ? I'm not sure :)It seems to me that the most logical explanation would be that each human race would have evoluted from a diferent primate race , but this also doens't sound very lickely, as for 1 single specie to achieve inteligence would be extremely hard , statisticaly for several species to give origin to diferent inteligent human species would be almost impossible.One interesting thing, is that for example, regarding the colour of the skin, i'm a caucasian, and lets imagine i wanna have a kid with a caucasian woman.It is possible to get that baby to be born with a black skin, trough genetic manipulation in the genes.., so it seems nature can select what colour the skin is depending on where he his born.., making black skin if we are born in africa, however a african can move to europe and have kids there, and they will be born with black skin again.., so, why are things like this ? why do people native from africa are born with black skin in africa ? I don't get this, some times in points in one direction ( more than one primate race evolution ), other times, points into a direction that i don't even know what it is...Anyone has any good theories on the evolution of our specie ?I hope i didn't bored anyone to death :)   
  No.   ;  any social science teacher not holding a fake degree will tell you that race is a cultural construct, not a biological one.As well, we came from the same primate (if thats what you believe), we are genetically too similar to have come from seperate ones. Besides the minor differences like skin color or eye color there is extremely little seperating us biologically. Socially however is a diffrent story.as I try to make my way through your post I find nothing scientific about what you have to say, nor do your arguments make sense. Are you trying to say that people you see walking down the street look diffrent from you, so they must have evolved from a seperate primate?? Thats actually quite assanine (sp?). Your about 100 years to late with this thinking, you would have fit in quite well with the eurocentric views of last century.;  "no"exactly what I was trying to say, only I used more words because I am not as smart as you, good job.Fankly the origional post infuriates me.   ;  you need to learn some biology. Idea is stupid from biological pov.Why: males and females of different races can have offspring, in any combination, and offspring can reproduce. Different species can not, and in rare exceptions, the offspring usually can't reproduce anyway. See mule, ligers and tigons, and other examples of interspecies breeding. If morphologically different groups can mate productively, it is not different species.And no, there is no way for two different species to converge and become more similar. And no, there is no way for evolution to go paralelly. The humans are nearly identical. Period. Even domestic cats or dogs are more different, and it's same species.   ;  nono guys, you are completely missing my point, i didn't said we came from diferent primates, that would be stupid, how could we all be compatible with internal organs and everything if we didn't came from the same specie.., i was just saying diferent point of views, what i'm talking about is how did nature made us so diferent, depending on where we live\borne.Why do nature manipulate genes to make us growth with diferent skins\eyes\height when we are in our native place of origin, but when we move it doens't   ;Quote:Original post by BrunoHi..,i say that i believe we all camefrom diferent primate species. Quote:Original dispution of earlier post by Brunoi didn't said we came from diferent primates, that would be stupidreally?   ;  Humans are single species. there were other species (neandertal, little humans in oceania, etc) that were really different, tho only one species of homo survived till present.Think of evolution as branching tree. There were some humans that evolved closely together. Then at some point humans started to spread around. And when groups of humans became separated so there is no mating between groups, evolution pathes started to diverge (each group adapted to their local environment) and we got whites, asians, blacks, etc. Humans did not evolve from primates in 6 different lines, it is similarly absurd to for example idea that different breeds of dogs evolved from different lizards.   ;Quote:Original post by Brunonono guys, you are completely missing my point, i didn't said we came from diferent primates, that would be stupid, how could we all be compatible with internal organs and everything if we didn't came from the same specie..,Unless I am misinterpreting the following quote, yes you did:Quote:[...]while i say that i believe we all camefrom diferent primate species.[...];  I meant primate races, not primate species, read my post, i made i mistake there :"I don't get this, some times in points in one direction ( more than one primate race evolution ), other times, points into a direction that i don't even know what it is..."And when groups of humans became separated so there is no mating between groups, evolution pathes started to diverge and we got whites, asians, blacks, etc.But wouldn't that take millions of years ? evolution like that is not done in thousands of years.
