Lucy

Lucy, a member of the Australopithecus afarensis species, is the most common and well-known of all hominid fossils ever found. The American anthropologist Donald Johanson discovered several hundred pieces of bone representing about 46% of the entire skeleton, including the skull, at Hadar in the Afar depression in Ethiopia, Africa in 1974.
Lucy was a female with a height of about 107cm and a weight of 28kg. She is estimated to have lived about 2.8 million years ago, wandering around the woods of the savannah in a bipedal upright walk rather than a quadrupedal posture after descending from the trees in East Africa. Lucy’s wide but short pelvic bones and thigh bones, which were turned inward, show that these hominids walked erect like modern humans. However, its conical rib cage, short legs, and small brain, as well as the mandibular structure, are more similar to those of anthropoids than those of humans. In addition, judging from her long fingers and toes, which seem suited to climbing trees, it is assumed that she spent most of her time in the trees like other anthropoids, rather than walking bipedally in an upright posture. Lucy was named after the Beatle’s song Lucy in the Sky with Diamonds, which was played at the party held to celebrate her discovery. Lucy is also known as "Dinenesh", which means "you are beautiful" in the local language in Ethiopia. Lucy is considered a very important fossil, providing the most direct evidence that our human ancestors were already walking upright millions of years ago, in line with the great progress of human evolution.
