LOL, what are you smoking? It is acceptable from various theories about the origin of human which is suppose to be from one original location. It doesn't matter if its origin is from Canada or Easter Island, LOL that is not the case here .
What I want to say, human differ biologically because of their geographical location. Human is a nomad by its nature, they indeed came from one original location, but when they relocate to different region of the earth, they develop their own culture and their characteristics change because of it (an evolution that taking thousands of years in the making). Hot weather in Africa, more pigment etc, cold weather at northern atmosphere, fair skin etc. Duh!
