The native americans originated, like europeans, from africa... scientists have managed to use DNA mapping (or something along those lines) to link Native american DNA with African. They say that the first americans passed into north america by an ice bridge between russia and alaska. When that Ice bridge melted they were cut off and left to develop on their own. Thus even if, based on the theory of evolution, they would have developed differently from the european human they still have the same roots in their DNA and thus just like horses and Donkeys, different breeds of Cats and Dogs etc etc etc the Native american is successfully able to mate with Europeans...or any other human for that matter...
i saw this recently too which touches upon this idea..

Tho this fossil has nothing really got to do with why the native americans or aboriginals are slightly different to Europeans Africans or Aisians.. this has got to do with the development of the root human, the Homosapian... it has already been prooven that these different types of human have the same DNA footprint...what needs to be proven is where and how that DNA footprint first came into existance.
Also lets say the comment left here about the flys not realising that a lightbulb will kill them was valid... taking the idea lets say that the lightbulb has been in existance for as long as the fly... the idea of Natural Selection and Darwins theory is that while the majority of flies would perish to the lightbulb, over millenia one or two flies would develop the brain capacity to realise the lightbulb was harmless.. that feature would be passed on from generation to generation, slowly at first but eventually to a point that there was clearly two species..the ones that are attracted to the lightbulb and the ones that are not..the ones that are not have longer lives, thus develop better, perhaps grow in size... and now these days this strain of fly has become a wasp, a bee etc... not in anyway threatened by the light. And this does not mean that the fly species would die out completely, it continues to co-exist with its more advanced cousins, and continues to perish to the lightbulb... same reason why monkeys and apes still exist today with us..
This fossil has qualities that display what would be similar to our flys minimaly higher brain capacity, its not the longer tail as someone said here, its the aposable big toes and the presence of nails rather than claws... you could imagine that this new form of lemur did not need big claws to dig into a tree trunk because it had a big toe that could hook onto it and grip him in... thus the claws become less essential and develop into nails...
I mean i amnt in any way an archeologist or paleantologist... but you have to admit that the fact that this hybrid species has even been found in the state it is in is something incredible.. and its worth considering how it applies tot he development of primates at least..and perhaps if you then come around to the idea humans too
