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. [Directed by Igor Coric, Artrake Studio, narrated by Alexandra Panzer, music by Nikola Radivojevic].

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

Why do we have hair in such random places?

Early hominins in Africa shed fur for sweat glands to cool off, a pivotal adaptation for an active, terrestrial lifestyle.

Head hair evolved not just for protection against the sun but also reflects human migration and adaptation to various climates.

Our scattered body hair serves diverse functions, from facilitating sweat evaporation to signaling identity through scent.
