Re: Anthropology break
:( I am not sure I completely understand what you're saying. From what I understand the genetic similarities in what is being referred to as racial groups is a result of some slight regional variation and slight amouts of reproductive isolation (i.e. it's harder for someone in Greenland to reproduce with someone in Nigeria) but the result is not genetically distinct populations but a gradation of genetic traits across bordering populations. Can you give me a "for example"?
