I mean really, are you serious? Not just developed once but many times? Tor what reason? What caused this convergent evolution? The rest of the world did the whole animal husbandry thing long before Europe, all lactose intolerant.

Nope, sorry anon, not going to cut it. I think there's a lot more to this. For example, the various forms of melanin are not trivial changes, melanin is highly electromagnetically sensitive. Take melanin in the eye, when such an animal is exposed to power frequency ELF fields in the presence of light, even dim red light, a suppression of melatonin synthesis occurs. This is absent in albino animals and blue eyed people. Thus, apparently, melanin is required for ELF field transduction. Hence neuromelanin, perhaps.
