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.
Lesson by Nina G. Jablonski, directed by Igor Coric, Artrake Studio.

Thanks for watching! If you want to learn about other weird body questions you don’t want ask aloud, wacky creatures, hidden historical figures, the secrets of space, brain-busting riddles (and

"Thicker longer hair protects our sensitive scalps and keeps our brains from overheating"

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

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

“Disperse our sweat smell more effectively for 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.

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

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

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

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

when eyelashes are supposed to protect your eye but end up falling in it

This channel is a blessing! Continue making stuff!

I thought the reason for eyebrows was more for redirecting sweat from your eyes than expressing emotion. It was important to be able to run down our prey and maintain accuracy with our stones and eventually (obviously) spears.

This is all very hypothetical. Not watching this vid could have given me the same amount of knowledge than watching it, which is there are so many things that are just a mystery for us.
