Nudity
Before clothing, people had ornamented their bodies with jewelry, scarification, tattoos, and body painting. Different ornaments and clothing showed both individuality and group membership. More and better clothing and ornaments were worn by people in higher positions in society. For many thousands of years, humans lived in tribes of about 150 individuals. They rarely met strangers. When populations grew, people began living in contact with larger groups. They met others that they did not know. The difference between private and public space began. Clothing and ornamentation worn in public space became important to show others who they were and their place in society. In private space, which included only others they knew, people did not to wear clothing when it was not needed. They bathed, slept, and worked together naked.
