Penn State University anthropologist Dr. Nina Jablonski explains how different shades of skin color arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

This film is appropriate for science classes from middle school to college. The content connects to key concepts in biology, human biogeography, genetics, and anatomy and physiology. Chemistry and biochemistry classes will appreciate the focus on the effects of UV radiation on DNA, folate degradation, and vitamin D synthesis.

Skin color is a product of our evolution, and should never have been judged as something good or bad.

lesson of the day: stop being racist, skin color doesn't make you superior, it just adapts you to the environment where u live.

When you come for biology, but actually really enjoy the subject matter and have a fun time learning.

I’m not here because of bio class. I just smoked a blunt and now I’m ready to go down a rabbit hole 🕳

I'm a dietitian and a teacher at a university, and this video was INCREDIBLY useful to understand the relation between our ancestors, where they lived, our skine tone, where we live, and our diet with the production of vitamin D. Thank you!

I must've increased my vitamin D...never noticed til I started taking D3 for arthritis & bulging discs.

I'm sometimes struck by the response I get from some of my peers when I ask them "Why do you think people with darker skins tend to be located in regions near the equator?" I recall asking one friend this and his response to me was "Genes". I then asked "Why do you think they have THOSE genes?". It seemed that variations in skin color as an adaptation - rather than some random fluke - escaped him. Watching this video, I learned something NEW about skin color. I used to think that fairer skinned people simply LACKED a certain DENSITY of melanin that would otherwise make a person dark. I didn't realize there was another COLOR of skin melanin. Interesting!!
