The science of skin color - Angela Koine Flynn

When ultraviolet sunlight hits our skin, it affects each of us differently. Depending on skin color, it’ll take only minutes of exposure to turn one person beetroot-pink, while another requires hours to experience the slightest change. What’s to account for that difference, and how did our skin come to take on so many different hues to begin with? Angela Koine Flynn describes the science of skin color.

“Ew, I hate you because your skin has more natural protection than my skin!”

This is the most positive comment section I’ve ever read on a YouTube video.

And some people say you cant learn anything from YouTube

[jossylopes]

I wish everyone knew about this. But instead people are just out there judging others by their skin color.

[learniteasy]

I learned this when i was 9 years old.

I cant believe how people didn't learn this all their life.
And blame humans.

I am homeschooled and I can't believe that they never taught this in all of my 6 years of public school. Everyone needs to watch this video! ✊🏻✊✊🏼✊🏽✊🏾✊🏿

The last sentence brought goose bumps literally for a minute

[amydocherty]

It’s crazy because skin colour should be celebrated for the impressive ability of our bodies to mutate and adapt to different environments

“even though i look like a burnt chicken nugget, i still love myself”

My skin color has drastically changed since my birth. My mom doesn't like that I have darker skin tone than before she keeps asking me to use home remedies and I am tired of her racism against my skin.

It absorbs light, but it certainly does not reflect character

I felt that one. I always get teased of my dark skin. That phrase boosted my confidence❤

[RONJAE]

It’s too bad the last sentence even has to be said

[amartyapandit]

Am north indian.

My colour varies from time to time

Am a chameleon changing from little whitish to darkish
And I never wonder why

[unlockwithjsr]

This video has to be the top YouTube recommended video at this time

[manasichavan]

Beautifully explained! I am a brown skinned biology student who studied evolution. And man, I am overly proud of my melanin concentration. It's one of the best examples of evolutionary adaptation of humankind.

Every human beings on Earth is beautiful in its own way. No matter what color your skin is, just be confident.

Skin colour may absorb light, but it certainly does not reflect character 🙂
Genius ✌️

Pretty pathetic that these adaptations are what our ancestors fought and hated each other over. Pretty pathetic that tons of people are still hating and discriminating against people with darker skin when it's literally an adaptation to protect us from the sun...
