Why Did Humans Start Wearing Clothes?

How Clothing Began

The video explains how humans went from being largely hairless to wearing clothing, and how clothing later took on social meaning.

Evidence for Early Clothing

The earliest clothes have not survived. Garments made from skins, fur, plant fibers, and bark decay much more readily than stone tools, so researchers rely on indirect evidence to study clothing’s history.

Clothing lice offer one clue. Unlike head lice, clothing lice live in garments and come onto the body to feed. Genetic estimates of when the two types of lice diverged suggest that clothing was in use at least 83,000 years ago, and possibly as long ago as 170,000 years ago. The video refers to studies from 2003 and 2011.

Archaeological evidence also comes from a cave on Morocco’s Atlantic coast, called “Smugglers’ Cave” in the subtitles. Researchers found bone tools dated to roughly 90,000–120,000 years ago. Their shapes and wear suggest they were used to prepare hides. Cut marks on the bones of small animals—including foxes, jackals, and wild cats—suggest the animals were skinned for fur rather than primarily for meat. No garments were found.

Clothing as Protection

Humans lost much of their body hair long before clothing appeared. The video links early hair loss and dark skin to evidence suggesting these changes began around 1.2 million years ago. Hairlessness helped human ancestors cool themselves by sweating, especially during activity in hot conditions. But bare skin also meant losing heat at night and in cold climates.

Clothing likely helped address that problem. Rather than evolving thicker fur, humans could add or remove animal skins as conditions changed. Clothing may also have protected people from sun, thorns, insects, and scrapes. Skins could serve other practical purposes, too, including as blankets, bags, or shelter material.

Bone needles with eyes, dating to about 40,000–50,000 years ago, made it possible to cut and sew more fitted garments, such as sleeves, trousers, and hoods. Fitted layers could trap warm air and provide better protection from cold and wind. The video presents this as a possible advantage for modern humans, while noting that the idea is debated and that Neanderthal clothing may have been more capable than a simple cloak.

Ötzi’s Clothing

The 5,300-year-old man preserved in Alpine ice, known as Ötzi, wore a fur hat, a jacket made from goat and sheep skin, and grass-stuffed boots with bear-skin soles. His clothing illustrates how sophisticated garments had become by that time.

Clothing as Social Communication

Clothing later became a way to communicate. Materials, colors, ornaments, and rules about who could wear particular garments could signal a person’s origin, group, or status.

Standards for what should be covered—and the shame associated with nudity—have varied across societies and periods. The video argues that this sense of shame is learned rather than innate.

Overall, the video presents clothing as a practical survival technology, especially for coping with cold, that later became part of social identity and cultural rules.
