We already dealt with the racist nonsense about Black people being a different species than the rest of us. By the way, this is just another way of saying, “Niggers aren’t human,” which is exactly what a lot of anti-Black racists say about Black people in precisely those words.
I hate to break it to these guys, but Black people are as human as the rest of us. We are all one species.
I did a lot of research on the question the other day because I wanted to see if there was anything to the racist argument. The overwhelming opinion, based on multiple lines of excellent evidence is that all races of human are part of a single species. I won’t go into the lines of evidence here, but you can go look them up if you want. And it’s good science too, not junk science.
One of the lines is that no human race has any particular type of DNA that is particular to its own race. In different species, the new evidence is that all species have areas of DNA that are specific to just them. This is true even in species that can and do interbreed.
In studying two types of butterflies in the Amazon that readily interbreed, it was found that one area of DNA in each species never transferred to the other. Obviously when you mate two different lines, you end with each line contributing a lot of its DNA to the offspring. This is the DNA that carries over so to speak in interbreeding. The areas of DNA that never carried over or transferred in interbreeding were two areas: one that gave it its blue flavor and another that deals with how the blue butterfly is able to recognize others of its kind. In the orange butterfly, the non-transferring DNA was also for orange color and for how the species recognizes its own species. This is where we get the notion that “species breed true.”
Another is that humans can readily interbreed with other humans. For an example of what happens when humans breed with other hominid species, we can look at the evidence of human-Neandertal breeding.
Human-Neandertal breeding was very difficult and most of the offspring did not survive for some reason. Neandertal males mating with human females was rarely successful. However, human males mating with Neandertal females apparently worked sometimes.
The example given that species can interbreed is dog and wolves. However, science now says that dogs and wolves are one species. From my study of birds, when two different bird species start interbreeding a lot, after a while, they usually merge them into one species on the basis that they interbreed.
Crossbreeds of different species often produce sterile offspring. Yes, a horse can breed with a mule but the offspring is a donkey and donkeys are sterile. I believe that ligers, the offspring of lions and tigers, are also sterile. There are other species that can interbreed, however the offspring are weak, sickly and fail to thrive.
If any human races were separate species, we would expect to see something like the results of the human-Neandertal interbreeding and we don’t see that. Blacks and Whites can interbreed just fine, immaculately, in fact.
The question then boils down to whether any races could be said to be subspecies. The German Wikipedia has done some work on that and they have concluded that based on geographic separation, Negritos, Aborigines and Khoisan (Bushmen/Hottentots) could probably be seen as subspecies. On looking at their work, I think the writers on the German Wiki are basing their argument on good, solid science.
I would also argue that these three could be seen as subspecies based on genetic distance. The genetic line of Negroid Africans specifically does not go back all that far. They are a new race that only arose 9,000 YBP.
However, the Khoisan are one of the oldest people on Earth with a specific line going back 53,000 years.
Previously, a type of Negrito Australoid in Thailand, the Orang Asli, had been found to be the oldest race of living race with a line going back 72,000 years.
The Aborigine of course are very ancient. They are quite distant from all other humans. In fact the two races with the greatest distance between them are Aborigines and African Negroids. If anyone would have a hard time interbreeding it would be them, but there’s no evidence of any problems. On the other hand, few if any of them have bred at all. African Negroids and European Whites are dramatically closer to each other than Africans and Aborigines. If Africans and Aborigines are one species, how could Africans and Whites be two species? Makes no sense.
It is important to note that by their nature, all subspecies can interbreed. They are only called subspecies because for whatever reason, they only live in a restricted geographical area. In addition, there are some anatomical and genetic differences in all subspecies. At some genetic and anatomical difference level, two types of a species are said to be separate subspecies. Since no humans are restricted to any separate geographical areas, we cannot use that metric for setting aside human subspecies. However, I would no problem with setting aside Aborigines, Negritos and Khoisan as human subspecies. There’s nothing derogatory or racist about that statement, at least to any rational person, which leaves out all SJW’s.
