afarensis shows strong sexual dimorphism in that the body sizes between males and females are quite different; however, sexual dimorphism in other primates is usually characterized by size differences in bodies and teeth. Fossil evidence shows that male Au.

Why is the skeleton of Lucy anthropologically significant?
Because her skeleton was so complete, Lucy gave us an unprecedented picture of her kind. In 1974, Lucy showed that human ancestors were up and walking around long before the earliest stone tools were made or brains got bigger, and subsequent fossil finds of much earlier bipedal hominids have confirmed that conclusion.
Is Lucy the oldest skeleton?
Scientists today announced the discovery of the oldest fossil skeleton of a human ancestor. The find reveals that our forebears underwent a previously unknown stage of evolution more than a million years before Lucy, the iconic early human ancestor specimen that walked the Earth 3.2 million years ago.
