What the 3.2 million-year-old Lucy fossil reveals about nudity and shame

Fifty years ago, scientists discovered a nearly complete fossilized skull and hundreds of pieces of bone of a 3.2-million-year-old female specimen of the genus Australopithecus afarensis, often described as “the mother of us all.” During a celebration following her discovery, she was named “Lucy,” after the Beatles song “Lucy in the Sky with Diamonds.”

Though Lucy has solved some evolutionary riddles, her appearance remains an ancestral secret.

Popular renderings dress her in thick, reddish-brown fur, with her face, hands, feet and breasts peeking out of denser thickets.

This hairy picture of Lucy, it turns out, might be wrong.

Technological advancements in genetic analysis suggest that Lucy may have been naked, or at least much more thinly veiled.

According to the coevolutionary tale of humans and their lice, our immediate ancestors lost most of their body fur 3 to 4 million years ago and did not don clothing until 83,000 to 170,000 years ago.

That means that for over 2.5 million years, early humans and their ancestors were simply naked.

As a philosopher, I’m interested in how modern culture influences representations of the past. And the way Lucy has been depicted in newspapers, textbooks and museums may reveal more about us than it says about her.

From nudity to shame

The loss of body hair in early humans was likely influenced by a combination of factors, including thermoregulation, delayed physiological development, attracting sexual partners and warding off parasites. Environmental, social and cultural factors may have encouraged the eventual adoption of clothing.

Both areas of research – of when and why hominins shed their body hair and when and why they eventually got dressed – emphasize the sheer size of the brain, which takes years to nurture and requires a disproportionate amount of energy to sustain relative to other parts of the body.
