A Simple Scientific Explanation from Bill Nye Demystifies Skin Color and Stupifies Racism

If you know Bill Nye, you know him as the Science Guy. Not so long ago, he broke down how important it is to wear protective masks in the pandemic we are in and mentioned the various types. Now he is onto racism, and why the practice is unreasonably foolish.

In a short one-minute TikTok video, he addresses the science behind the different skin color adaptations. According to Bill, the different continents around the world receive unequal measures of ultraviolet light at different latitudes. The zone nearest the equator gets most UV rays, and that is where Africa falls.

Before migrations happened, everyone was a native of Africa. But when people spread out to different continents, their skin adapted to the lower ultraviolet light supply. This resulted in lower vitamin D levels, and therefore the skin became lighter. Too much vitamin D breaks down the folates on the skin, darkening it. Too little of the vitamin will cause the skin to maintain its light color.

Bill’s emphasis is on the fact that humans are of the same species, only with different colored skin. He conclusively points out the rampant discrimination that is meaningless and calls out for change.

The video had 74K comments, 4.4M likes, and 19M views on TikTok. The matter has been oversimplified but it drives the point home.
