Well, to me it looks like "speciation" as usual, which is really just ordinary variation according to Mendelian principles of inheritance, the way we all differ from our parents: if a few of us started an isolated colony (which has happened unnumerable times in the history of the human race), we'd become an identifiable race, but still be humans.
Uh, the different species of goatsbeard cannot interbreed.
They produce sterile hybrids.
So, it isn't like different "races" of humans at all. All the races of humans can interbreed quite successfully.

It's "melanin", FYI
Melatonin is a neurotransmitter.
Melanin is skin pigment.
