Reseña
Fossil of an Australophitecus afarensis, discovered in 1974 in the Afar region, Ethiopia. It is the skeleton of a female about 1 meter tall, weighing approximately 27 kg (in life), about 20 years old (wisdom teeth were just out) and who apparently had children. The name Lucy comes from the song Lucy in the Sky with Diamonds, by The Beatles, which was being listened to by the members of the research group the night after the discovery. Her study was key to understanding the hominization process.

Biografía
Lucy is a female skeleton, with 52 bones, found in Afar (Ethiopia), belonging to the species Australopithecus afarensis. This species lived between 3 and 3.9 million years ago in East Africa (Ethiopia, Tanzania, Kenya) and preceded the genus Homo. She lived in cleared forests and had arboreal activity, where she collected fruits, slept or played. The latest studies reveal that the first remains of carved stone could have been the work of Australopithecus. They were bipedal, with a smaller cranial capacity, between 375 and 550 cc. There was a high degree of sexual dimorphism (physical difference between males and females of the same species). Their diet was mainly fuitarian, which is why they have large incisors. Their forehead was narrow with a marked supraorbital torus and all this gives them an appearance similar to that of a gorilla. The shape of the pelvis indicates upright bipedal walking. The birth canal was smaller than the current one. Their arms were long arms and their fingers and toes were curved.
Lucy was approximately one meter tall, weighed about 27 kilos and had recently erupted wisdom teeth, which suggests that she was approximately 20 years old when she died after falling from a tree. She had had children, although it is not known how many. Her brain size was similar to that of a chimpanzee. Her arms were very robust, which reinforces the idea that she spent a lot of time moving through the trees using them. According to fossils found in Hadar, Lucy appears to have lived within a small social group.
In 1974, a team of paleontologists discovered her remains and this represented an advance in the knowledge of the hominization process. By walking upright, a connection was made between four-legged primates and human bipedalism about 3.2 million years ago. Through this fossil it was proven that the ability to walk upright, like modern humans, was prior to the growth of the brain.
Her discoverers gave her the name of Lucy because in those days of the discovery they listened to the song Lucy in the Sky with Diamonds, by the Beatles, on the radio. Currently, her remains are in a safe at the National Museum of Addis Ababa (Ethiopia).
