When Did Light Skin Appear in Modern Humans?

Light skin appeared in modern humans about 20,000 years ago, like when a new color showed up on your favorite crayon box.

Imagine your family has been living near the beach for a very long time. They spend most of their day outside, under the bright sun. Over many generations, their skin got darker to help protect them from that strong sunlight. This is how dark skin came about, like when you tan after spending too much time in the sun.

But then, something changed. Your family started moving farther inland, where it wasn’t as sunny all the time. They didn’t get as much sunlight anymore. Because of this, their skin gradually got lighter over many generations, like how your shadow gets smaller when you move closer to a lamp.

This lightening of skin happened slowly and took thousands of years. It’s like watching a flower grow from a seed, it doesn’t happen all at once, but little by little.

So, the next time you see someone with lighter skin, think about how they might be related to people who lived far away from the sun a long time ago! Light skin appeared in modern humans about 20,000 years ago, like when a new color showed up on your favorite crayon box.
