I know what you are saying. I look at it like this. Branches of a tree. Some bloodlines, such as RH- evolve separately and are kept "in the family" until a hybridization occurs. I view it as natural, separate evolutions that produce different "humans" and they hybridize from time to time. I like to think there is nothing 'unnatural' about any of it. Many hybridization have occurred throughout time and many more will occur, but the more "isolated evolution' that occurs, the more significantly 'different' the hybridized 'species' is. ie 100 years of separation does not lead to much change in the genetic code, while 10,000 years might produce some substantial difference. What happened when lemuria and atlantis hybridized? neanderthals and denisovan? etc etc
