Why do we have hair in such random places? - Nina G. Jablonski

Discover how humans lost their fur as they evolved from primates, and why we still have hair on our bodies.

--

We have lots in common with our closest primate relatives. But comparatively, humans seem a bit… underdressed. Instead of thick fur covering our bodies, many of us mainly have hair on top of our heads— and a few other places. So, how did we get so naked? And why do we have hair where we do? Nina G. Jablonski explores the evolution of human hair.

"Thicker longer hair protects our sensitive scalps and keeps our brains from overheating"
Bald people: Why are we still here? Just to suffer

[AdityaSista]

"I'm here to protect your eyes from debris" - the eyelash that is skiing on my eyeball.

TED-Ed:
- Why don't we have fur?
Mediterranean and Middle Eastern men:
- We don't? Really?

Only one thing: the oil and fluid produced by sweat glands isn't smelly by itself; it's the bacteria that eats it that produces the smell! It's a twist of fate that this video showed up on the day of my Anatomy test on the Integumentary System

[self-proclaimednimwit]

My dad overhead this and asked why his arm hair's so lusterous, but his scalp is smoother than a spoon?

[Ironmat]

“Disperse our sweat smell more effectively for recognition”
Me: Yes well it doesn't seem like the good type of recognition

I always thought hair was also a protective measure against insects. If one crawls across your bodily hairs, you feel it faster than on bare skin. So extrmeties like fingers & toes have hair too

I think eyebrows also help to keep debris out of our eyes, because I once had my eyebrows trimmed and I noticed I was getting more dust in my eyes than I normally do, so I don’t have them trimmed now and I get less dust in my eyes, so perhaps they are to protect our eyes as well as communication

Imagine being jealous of a monkey because it's flaunting its fur at you.

Basically, long story short: We don't know.

[usedtissuepaper]

when eyelashes are supposed to protect your eye but end up falling in it
“you’ve become the very thing you swore to destroy!”

[the-vuk]

Eyebrows are also important to drive sweat around your eyes so it doesn't get into your eyes. Very useful.

[Skythrle_]

I feel like everytime i watched a ted ed video I increased 10 braincells

[reneeaquino]

Imagine how soft hugging each other would be awhhh

[Thats_So_Sahi]

I am currently learning more on the internet than my whole 12 years of school life. Fascinating ✨

[anshumanabhishek]

The real question should be, "why we don't have hair anymore?"
Now we are literally questioning from where we started 😂

[annabusic]

I love how TedED always somehow makes videos about things I wonder about..

[samipenicho]

"underdressed" Honest to god I have so much hair on my body I'd pretty much qualify as a monke.

[santiagohernandez]

This channel is a blessing! Continue making stuff!

[ahmedyaaqoub]

I think eyebrows may have another utility, which is protecting eyes from sweat coming down from forehead!
