Race is another term for subspecies, and most scientists use the subspecies to designate geographical variation within a species. Scientists have also tried to define subspecies within the human race, but have so far failed. Yes there are noticeable differences between, say, a Native American and an African, and there are also differences between Eurpeans and, say, Australian aboriginines, but scientists have found that whatever characteristics they use (e.g. skin tone, blood type), there is more variation within any given population than there are differences between populations. Therefore all attempts at defining races or subspecies within humans have so far failed.
Ironically, scientists have been more successful in defining subspecies among other species besides humans, perhaps because it is less controversial to do so. For example, horses are divided into several subpecies, albeit they have all become extinct in the wild. As for dogs, they are not a geographical variation of the wolf, but a different, domesticated species. Since dog breeds are the result of selective breeding, they are not valid races scientifically. A good example of a species with well defined subspecies is the salamander Ensatina eschscholtzii, with 7 geographical races, or subspecies currently recognized. These races can be quite different from one another in color pattern, but they interbreed freely at the boundaries of their ranges.

Humans are different from animals cus God says so. So humans have races instead of subspecies and breeds. And this pleases God and his merry band of delusionists.

Some Pit bull's have Red Noses and some have Blue even and they are the same breed.
