Humans are most closely related to which living primate?
Was Lucy an ape or a human?
What distinguished Lucy from other apes?
she had a wide pelvis, which enabled her to walk
What effect did the geological events in the Great Rift Valley have on Lucy's walking ability?
tectonic activities resulted in the formation of a Great Rift Valley in Africa, which blocked the moisture-filled clouds that brought rain to the forest. The wooded areas eventually gave way to grasslands, and food became scarcer. As a result, early hominids had to adapt to more effectively move from place to seek food, which encouraged the development of bipedalism.
