lucy
n. countablen. the famous skeleton of an early human relative found in Africa. She lived about 3.2 million years ago and helped scientists understand how humans started walking on two legs.
n. the common name given to AL 288-1, a fossilised partial skeleton of the hominin species Australopithecus afarensis. Discovered in Ethiopia in 1974, it provides critical evidence for the transition to bipedalism in human evolution.
Scientists studied Lucy to learn how early humans walked.
The discovery of Lucy challenged previous theories by proving that early hominins walked upright long before they developed large brains.
While other specimens have been found since, Lucy remains the most iconic fossil in paleoanthropology due to the remarkable completeness of her skeletal remains and her pivotal role in mapping human ancestry.
From Middle English Lucy, from Old French Lucie (notably after the Christian martyr Lucia of Syracuse), from Latin Lucia (feminine of Lucius, a Roman praenomen), from lux (“light”). The name of the Australopithecus skeleton came from the Beatles song “Lucy in the Sky with Diamonds”, which was being played repeatedly at the dig site camp at the time of the discovery. The slang term for LSD also derives from the song name, which many believe is essentially a reference to the drug.
Used as a proper noun to refer to a specific archaeological specimen; typically takes no article.
