A petite fossilized being of the species 
Australopithecus afarensis, she lived 
in Ethiopia about three million years ago, 
walked upright, three and a half feet tall, 
and had a pubic arch similar to that 
of a modern woman, but a very small brain.
She was named for the Beatles song 
“Lucy in the Sky with Diamonds,” 
which was played loudly, over and over 
again, in the camp of the anthropologists 
who found her in the Awash Valley 
of the Afar Triangle at the foot of a gully.

Another Lucy, a chimpanzee born 
in 1964, learned American Sign Language. 
Using 140 signs, she was interviewed 
by the New York Times and invited 
the reporter into her tree. He declined. 
She could have offered to make him tea.
As an adult, she became destructive 
when displeased, so her adoptive parents 
sent her for rehabilitation in the jungle 
of Gambia, but she was depressed there, 
often signing “hurt.” She rejected male 
chimpanzees, preferring a human mate.
A space mission to the Trojan asteroids 
orbiting the sun with Jupiter is also called 
Lucy, after the fossil lady from Africa 
whose existence shook up the hominin tree. 
Lucy the spacecraft will probe mysteries 
of organic chemistry and planet formation.
And what about Lucy, the woman raised 
on I Love Lucy, who often hears her name 
called at dog parks? She is waiting to learn 
how hominins morphed into humans, why 
chimps and monkeys don’t talk, and how 
worlds bloomed in the field of space.
