How do they know Lucy was human?

Ultimately, evidence from other parts of Lucy's skeleton, such as her teeth and pelvis, demonstrated that she was, in fact, a hominin (see Kimbel & Delezene, 2009, for a detailed description of Lucy's pelvic anatomy and its locomotor implications).

What evidence did Lucy have for human evolution?

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. Bipedalism, it seems, was the first step towards becoming human.

The fossil is slightly less than 3.18 million years old. None of the bones were duplicates, supporting the conclusion that they came from a single individual. The shape of the pelvic bones revealed the individual was female. Lucy measured just 1.05 metres tall and would have weighed around 28kg.

What did Lucy the first human eat?

Lucy probably ate a mix of foods, including ripe fruits, nuts, and tubers from both the forest and savanna.
