I've read that it was lack of vitamin D that caused Europeans to turn white, thousands of years ago.

That's interesting. Since most Europeans are Aryanic, they would have originally had a brown skin like Iranians or northern Indians. As they moved to the north with less sun, they would have lacked Vitamin D and had lesser melanin. Those that moved south gained melanin to protect against the sun.

That's called evolution! Better equipped - survival, and providing the gens to the next generation.
