Lucy:

Australopithecus Afarensis is a relative but extinct species of man and chimpanzee. These creatures existed on the planet three to four million years ago. Hundreds of fossils of this species have been discovered in Ethopia, Kenya and Tanzania.One of these creatures is named Lucy. Lucy’s fossils were discovered in 1974 by paleo anthropologist Donald Johansson and his team in Ethiopia, these fossils are 3.2 million years old. These fossils include the arm, leg, head, hip, spine and ribs as shown in the picture.

At first glance, all these bones may seem like very few bones but when observe deeply it seems that some of the bones are of the right side of the body and some are of the left side. This means that the bones on the left side can be molded by looking at the bones on the right side and the bones on the right side from the bones on the left side. Then the whole structure is completed, taking into account the bones of other similar creatures.

Lucy was an adult female. By looking at the bones and teeth of the body, males and females as well as ages can be detected. The structure of the hip bones determines whether the animal is male or female, and the age is determined by the teeth. Lucy had molars in her jaw and children do not have molar teeth.

The physical features of Australopithecus Afarensis were a mixture of human and chimpanzee characteristics.
The hip and leg bones indicate that Australopithecus Afarensis were able to walk on two legs like humans. Like humans, their canines were small, The sharp teeth in the mouth are called canines but the small size of the skull Flat noses, protruding jaws and large arms in terms of body are features found in chimpanzees and Orangutans and Baboons.
