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.

Lets just all be grateful we have skin..
lol you still have skin I shead that years ago...
@diepewpie You sad asf
@diepewpie Why you deleted your comment?
wait so you’re not supposed to skin and eat your partner’s skin?
@diepewpie Pick Up On It? Sounds Very Fishy 🤔
“Ew,I hate you because your skin has more natural protection than my skin!”
😂
XD
XD lol. Let's be honest there are a lot of things racists are jealous of
Racism is the uglier side of tribalism. I know people who think blondes are better than Burnett's. Blue eyed people are better than brown eyed. Yet all people of any difference can have children. Don't want to believe . look around!
@Zachary Williams the second for real we wouldn’t be having all the insecure people
This is the most positive comment section I’ve ever read on a RUclips video.

that would be my moommy
The last sentence brought goose bumps literally for a minute
+Natesh Bhat true
+Natesh Bhat why? We are all animals dependent on our planet. We do not exist in a vacuum.
Seconded
Yep
Oh my God yes, it did... Great script
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 actually didnt learn about this till like a week(ish) ago
Me too I learned it at 11 year old it depend on the education system I guess
I learned this now im 11🙂
You guys are so young wow

I wish everyone knew about this. But instead people are just out there judging others by their skin color.
jossylopes - They are stupid’s. Don’t worry. Dark skin people are very attractive and beautiful
dark skin or light skin they are all beautiful
Honestly, I love dark skin. It's so pretty. But others don't feel the same.
And technically dark skin is better is you're facing direct sunlight.
@@Pathologymadesimple who is they???
Yeah
It’s crazy because skin colour should be celebrated for the impressive ability of our bodies to mutate and adapt to different environments
To celebrate something you are born with is the same as to discriminate for something you are born with.
Rai Hanzo nothing to do with born with. I’m talking about celebrating the amazing nature of life through science. It’s brilliant how our bodies adapt
and mutate to environmental changes without our direct control
@@amydocherty7317 I don't get it, how do you celebrate nature?
By acknowledging that your and others skin maybe different, but the basic beneath is all the same, and whooooom! You celebrated nature
T M Thank you! I forgot to finish my reply to them... I’m saying we should celebrate the fact that these differences have occurred out with our control, like it’s SO amazing that mutations of such can occur
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.
Same Indian fam
Don't listen to her.
She is too narrow-minded
*colorism
My mom always say stop using remedies
Indians are pretty much white people the only difference is your culture and skin color
This video has to be the top RUclips recommended video at this time
It’s too bad the last sentence even has to be said
So true. Precisely what I thought too.
What's wrong with the last sentence?
Ahh, now I think what this comment means...well my reply is completly true, and scientifically true too! It is just covered up by the leftist lies though... :(
Exactly what I thought as soon as I heard it. I thought: “wow, to think you have to tell millions of people that”...
James Hawkins you don’t 😂
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❤

I didn't know lego people were considered a race
We all really need this video right now.
I was expecting this comment section to be very racist.
i guess this is not the type of video they look for and or the concept is too difficult for them to understand.
Sxuril ditto
ignorant people don't watch science videos
B74CKB15H0P thanks i needed that
This is a ted ed comment section. We're all more intelligent than that.
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...
+Cassandra D Pack mentality is interesting to look at in regards to that, mainly because we can see forms of the same behavior in other animal species.
Very social animals are the only group of animals this kind of behavior can be seen in, many other species of apes and monkeys will harm or push individuals who are different from the pack for example.
Since most pack animals have a form of language as well (( Elephants are a good example )) we can actually see similar forms of discrimination happening in other species as well.
It may be an evolutionary trait that builds upon the fear of something different something odd, though studies on the subject tend to be very controversial.
We humans though tend to leave this behavior especially in countries that focus on higher levels of education and more mixed groups of people.
Countries with lower education tend to have higher levels of discrimination, so ignorance is a large part.
+Cassandra D This is why science and the knowledge it gives us is valuable and insightful. Too bad some people are just... well too stupid for these stuff. What's worse is that they are likely to deny these facts.
+Cassandra D Really, pretty much the only reason for skin tone being a factor of hate was during slave trade times, dehumanizing made it easier to keep it going.
Cole Loves You Actually people hated other skinned races long before the slave times
If it weren't for racism separating the tribes, would these changes even occur? Think about it.
What a breath of fresh air! Brilliant script, amazing animation and clear narration by Susan. Thanks Ted-ed ❤️

Yes
I'm glad I have lots of melanin
Queen A not really that beneficial if you live in a cold climate! I have alot but i live in one of the coldest countries in the world!
1strikerLacazate 505 what country do you live in?
Yay!
im pale soooooooo
Lucky. I wish I had it.
I love that this video clearly words the natural selection and evolutionary process correctly, as opposed to implying that humans adapted intentionally for their environments! I will be using this for my high school students.
Adapting intentionally is no evolution
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.
Skin colour may absorb light, but it certainly does not reflect character 🙂
Genius ✌️
@MunkeiGUN What? Class? 🤦🏻
@MunkeiGUN Oh sorry, I thought you said it reflects class. I'm so sorry, I understand now 😅😎
Sebastian Feuerstein 😂 you still have time to delete that comment
@Alok Singh not all uv rays. Very small count still pass
@Alok Singh everything you read from text books are not always accurate. Put proper research.
I’m dark skinned and I still tan when in the sun! We all tan! The darker your skin just determines how long you can last in the sun without sunscreen since your skin is acting as a sunscreen as it was designed to!
Yes, but it takes longer to you than it takes to me
@@EmyNhmm idk about that, I feel as if its individually based. For example, if im out in the sun for just a mere 2 hours, my skin complexion darkens considerable, but my brother is a light brown tone and it takes him longer to tan to a noticeable difference. So in that case its interesting lol
Soulxx trixx I guess you are right. But what I said is correct generally speaking then
@@OnlySolii Im dark skinned and can get darker within minutes of being out in the sun. I live in Phoenix so we get a lot of sun here lol. I also get lighter during colder months.

TED-Ed is great...the animations, the questions they choose to answer, the narration is all perfect. But it would be great if they included some of the sources in the description as well.
Epic ending :)

It wasn't tho. It was bs identity politics
The one end-all video for racism.
What you're saying is a small part of it but it only sounds as if were talking about america here which isn't the point. The majority of criticism comes from the percentage of stereotype each group carries. The typical blacks who act like they are gangsters or the overly smart and introverted Asian stereotype. The color only labels their stereotype. If a group of a certain color would act differently then they would be labeled that way too. the only reason why white's are labeled as anything is because they are the majority in this world.
arent*
+KorennRachelle I love how you instantly pinpoint whites as being racist, but don't bother to mention that racism can be and is present in every single race. To present it in such a way as to imply racism is a white thing, is racism.
+boy638 How so?
+boy638 Check a world map or a statistical data by countries of IQ. Both would be considered racist.
There are two type of racism. One that based on prejudice and complete nonsense, and one that is nothing but scientific data but "offensive" truth so it is considered racism.
The fact is that we are not the same, but even mentioning that which is a truth, is considered racist.
The choice of sound track used for this video is genius and the closing statement drove home the point. Welldone!
This video is so amazing!!!!! The animation as well as the content is just lovely ❤️...Thank you Ted for sharing !
That last sentence is golden. So fascinating to see that something so basic has been the source of so much pain and hate. More of this education and discourse, please!!
The last sentence was really amazing! such a strong meaning!
Every human beings on Earth is beautiful in its own way. No matter what color your skin is, just be confident.
♡
If that’s you in your pfp just wanted to say your really pretty.
i think that all bodies have a certain “flow” to them, where each aspect of your appearance works together to make you look beautiful. changing big parts of your body (nose shape, jawline, skin color) mess with how everything fits together
the last sentence nails it at all.... wonderful
Asides from skin colours, how did specific racial traits such as monolids, wide bone structure and lip/nose shapes evolved to fit certain racial categories?
Blurryink No such thing as “racial traits” as races don’t exist in nature, Many people from Asian have similar shaped noses to African people and the vast majority of African people don’t have “thick” lips. There are many non-African people who have full lips. People have been selective in talking about “racial” traits yet no one talks about the shape of an ear or size of the big toe, shape of the brow. What’s racial about the “lips” but not the “eyebrow” or “toe”? Race is simply a socio-political term. The continent of Africa contains the most genetic diversity than all continents combined. People only continue to “see” race because people assign HUGE MEANING to INSIGNIFICANT difference to physical traits. All human beings have the EXACT same alleles (ACGT) and due to environmental pressures, the result is different in the expression of genes. Nothing more and nothing less.
Khosians of Africa look Asian except for darker skin tone and woolly hair. They also have monolids like Asians. There are traits that are more prevalent in one group than another, but it does not mean another "race" of people cannot have that trait though. But obviously the trait that was more beneficial to a particular environment would become more prevalent than a trait that was not beneficial. This is why blacks have tropical limbs, different to whites who have bones structures that benefited them in their cold environment or Asians in their environment. The large nose benefited people in the heat or humidity as thinner nose was beneficial for those in a colder environment. But again although some nose shape (not all) may be due to adaption, it doesn't mean that people from these environments wont have nose traits that may not be best suited for that environment. I've seen un-mixed Africans with thin nose and un-mixed white Caucasians with large nose (that is why nose jobs are popular). A trait may be prevalent in a particular group because it benefited them, but it's not exclusive to that particular group. Some traits are not traits that are absolutely needed though they are beneficial in certain environments. Meaning people with thin nose can survive hot environments like people with large nose can survive cold environment. Now if we talk about skin color, that trait was a life and death matter back in the days because sun screen did not exist for pale skin, so living in hot environment would have been problematic if you stayed out in the heat for too long.
check out kentobento's video about asian eyes and other video about neoteny
I think it also has to do with the environment. What they ate, the kind of work they did, etc. For example, in Nigeria, the Igbo women usually have broader shoulders than in other tribes because they were predominantly farmers and they needed the added upper strength to farm. So, as time went on, their bone structures evolved. It took generations though.
"Blurryink*
That's where the tall white aliens came along 😂😂😂
how are we humans supposed to evolve to have awesome defense mechanism like animals (spit poisons, have spikes, etc) if we can't even handle different skin tones without triggering an all out world war?
Arul right ????
As seen in X-men comics or movies *WE CAN'T*
It's not because of skin color, if we were all the same, people would still find a reason to hate and segregate certain groups
we got fists
You seriously want to spit poison? Toungue kissing would be prohibited then 😛 unless it's not poisonous to human.
I hope everybody is safe right now, during the virus, the riots and protests. Just remember we’re all humans and the only way will get through this if we work together. ❤️ (amazing video btw)
Thank you sun for blessing me with my beautiful melanin☺️
LOL lol nope
Trust me, you don’t want to experience 2nd-degree sunburn. It’s horrible! Thank your superior skin for protecting you from that!
You mean “God”
@@suchastrangegirl36 I said what I said lol
@@suchastrangegirl36 no it was the genetics to be precise and scientifically speaking
And yet these adaptations spark discrimination among others.
+Pokemonlin99 That was really only inspired during the slave trade to justify keeping Africans and black people as slaves.
+Cole Loves You
Most likely cultural superiority and of course religion made it possible, it just happened to be beneficial economically.
+Cole Loves You
You do know that racism existed way earlier than slave trade, right?
If it weren't for racism separating the tribes, would these changes even occur? Think about it.
+George Cataloni
You've been entered into "The dumbest RUclips comment ever" contest.
Let's take a moment to absorb that last sentence v_v
Same reason why We see Blue Eyes, Monolids and Afros, they're all adaptations to better suit the environment
what are the environmental benefits of having no melanin?
To absorb Vitamin D more efficiently in colder places.
@@melontusk7358 Walk me through it...
@@temporary6715 don't worry, it's simple. There's a substance called "melanin" inside the human body, responsible for blocking harmful ultraviolet rays from the sun. The side effect is that it makes their skins darker. So the more melanin a person has, the darker his skin will be. People in tropical areas need darker skin to survive. However, ultraviolet rays are also necessary for bone growth and Vitamin D absorption. In cold places, where there's not much sunlight, people need brighter skin to make up for their lack of ultraviolet rays, which help them with Vitamin D and other things.
@@melontusk7358 You’ve misinterpreted my sarcasm. You are completely wrong.
- There are 3 types of uv rays. The two that reach earth : UVA + UVB
- Melanin allows for the absorption of UVB while preventing the more harmful UVA from penetrating the skin.
- Vitamin d is not “absorbed” from the sun. It is produced in the body (similar to photosynthesis) by the UVB rays which are ALWAYS present during the day.
- It is people without melanin who are deficient because they do not have any protection from the more harmful UVA rays. Also, sunblock blocks both UVA + UVB rays altogether which further limits vitamin d production.
- Your last sentence about people needing brighter skin to make up for lack of rays makes absolutely no sense. UV rays are ALWAYS PRESENT regardless of temperature... To reiterate melanin blocks harmful UVA rays (Causes cancer) Not UVB rays (absorbed to produce vitamin D)
- The melanated person can live anywhere because the UVA rays will never be harmful. The person without melanin has to live far away from the equator to avoid as much UVA as possible.
"It may absorb light but it certainly does not reflect character." This is a awesome quote especially in this time
*Melanin not only give skin and hair color, but also EYES*
that's what i was thinking !
It's in every cell of the human body including internal organs
Dr. Llaila Afrika teaches us that it's also highly concentrated in our brains and central nervous system
Time to get that ball rolling on my death to all green eyes group ✊
Yes but depends what type of Melanin, darker people have a higher ratio of eumelanin compared to pheomelanin which makes pigment darker, lighter people are more in the middle with the ratio, and have more pheomelanin and less eumelanin compared to darker
'It may absorb light, but it certainly does not reflect character.' Great way of ending the video :D more people need to realize this. Thank you for making such quality videos Ted-Ed!
that last line i love this channel
Every little thing in this world is so beautiful just see it the way it was meant to be seen♥️
So technically we were all black?
+Sand Shadow Yep , that is well known. lighter skin colors are mutations.

“Therefore, skin color is little more than an adaptive trait for living on a rock that orbits the Sun. It may absorb light but it certainly does not reflect character.”
Oh dear, hope someone realize the golden message of this video ❤️😍
« It may absorb light, but it certainly does not reflect character » PREACH 👏🏼👏🏼👏🏼
Remember Reach.... those guys got the worst tan ever, and it wasnt from the sun
This should be shown in all schools for kids. It's comprehensive information and the animation is nice.
Yes this seems to be very kid friendly and appropriate
Woow I didn’t know that
Thank you TED for teaching us more than we learned at school ❤️🥰😩
I hope more people see this soon in their recommendations
“It does not reflect character” say that louder for the people in the back
That little note about skin colour not reflecting character was unexpected but I appreciate it👏well done.
Last line !!! “May absorb light, but does not reflect character” 😍
Thankyou RUclips suggestion for this.
Perfect time to know about it
That last sentence... 😭😭😊
Am i the only one who is obsessed with my beautiful, dark brown skin?✊ Thanks for the information, it's nice to know the history of skin
I am white, but dark skin looks gorgeous!
Dark skin people are beutiful
I'm only obsessed with my light brown skin, when I'm sunburned.
It because of propaganda fed to you that you developed such as complex ...
I have white skin blue eyes but I know it doesn't make me special because it is common where I live 30% fair skined, 5% albino, 50% brown and 15% dark... Here I am not considered special I am considered average which is the Truth.. we didn't chose our colour .
In my opinion most attractive colour is brown with a hint of darkness both for men and women ❤.
✊🏽✊🏾✊🏿
"It may absorb light but it doesn't define the character "- this line ❤️
Reflect**
I saw a picture once of the earth and “skin color by area” and it was literally dark along the equator getting lighter as it reached the most north/south, it was cool
Loved this video, this biology is so fascinating. I'd be really interested in learning what the purpose of other physiological differences are (hair type, eye shape, nose shape, etc.)
"It may absorb light, but it certainly does not reflect character."
amazing presentation
TED ED I always come back to this video because it makes me feel confident and comfortable to be brown in a predominantly white town
I love how this video gives such powerful statements ❤️
The last line is heart touching.
All skins are beautiful ✨
Have a blessed day
Firstly , the graphics were awsome , and I was able to understand it. Ted-Ed tells new things interestingly.
AMAxING presentation, esp. the final bits of n'fo!
I already knew this, learned in school, but thanks for the clear video.
i loved this video particularly because the tone of the music helps me(adhd) pay attention more
Your opinoion is so reasonable! I’ll say
I think people never judge somthing by it’s looks. Skin color is just outcom of adaption!
May this knowledge help me in years to come.
How deep and beautiful is that:
"It may absorb light, but it certainly does not reflect character."
Nice seeing a lot of people appreciate their dark skin, but I’d also like to tell the people with really fair skin to also learn to love it. Fair skin is beautiful too and there’s no need to fake tan it
Oh, yeah fake tans are awful. It's perfectly okay to be white!!
Tanning is part of light skin, if you pale you spend too much time indoors
Thanks 4 presenting the science of skin color without bias or prejudice! Knowledge is power, and racism is a superficial and unfair way to judge someone!
The last words made me literally feel "WOW"
such beautiful explanation
Why do people think dark skin people don’t get darker in the summer ☀️
*White people
I am dark skinned i do tan but after 2-3 days or so i get as i was before!coool~
We do get darker, our skin just does not burn in the sun.
@Alok Singh A small amount does reach here.
@Sofia Diane why is it false just because it doesn't happen to you? My skin gets way darker I visit my family in Africa because I spend more time out in the hot sun. But gets lighter when in Europe because the heat where I live is not as intense and I spend majority of the time indoors. So its false in your case.
Plz guys, share this vid with as much people possible. Educate society about our skin, it doesn't define who we are ✊
"it may absorb light, but it certainly not reflect character"
the beautiful quote
B4 watching the video I knew they were going to go in a time machine to some thousands of years in the past but good very good content thou. It was very very educational to me and most ppl and ur last sentence WOW ADMIRATION😍😍
When I was little I had a theory that when a person lives in a different country for a very long time their appearance will slowly and subtly change, I guess it's kind of correct haha
Ofc... Like, humans ARE biological organisms and they WILL adapt to their surroundings ;)
The ending is just beautiful
That last line was EPIC! 🤟🏽
"It may absorb light but, it certainly does not reflect the character!" 👏👍
'It may absorb light, but it certainly does not reflect our character'
Good saying. Thanks
All the build up was for that last line "It doesn't reflect Character"
I was born in the U.K. but my family origins are from the Middle East. My skin colour changes very slightly depending on weather.
In the cold, my skin colour is more dark and in the warmth, my skin colour is more light. It’s strange and I never understood it but it’s cool.
Some people just don't want to except truth. ... it's too much to burst their bubble. ...peace and God Bless
