In regards to the sunscreen thing, white folk evolved in response to the rather overcast climate of the Northern hemisphere. The large melanin they once had would block out the precious sunlight they needed to craft Vitamin D (this was before we had acquired the ability to keep the Lac Operon gene on indefinitely to get Vitamin D from milk), so of course we had the Vitamin D deficiency among the populace. But not for those with less melanin than usual! So began the natural selection of those with less melanin to out-compete those with more melanin in the North, the arms race of getting Vitamin D to become more fit for survival and reproduction, and the incremental change from black skin to white skin.

Course since this is 4chan, this could all just be one big shitpost, but I got to use my Biology degree for something in this economy god dammit.

Here's a lovely line of thought. Let's stop.
