the artifacts she discovered offered evidence that early hominids lived in Ethiopia about three million years ago.
Mary Leakey's discoveries, such as the Laetoli footprints and the skull of Proconsul africanus, provided critical evidence for the theory of human evolution. They showed that upright walking predated the development of a large brain, challenging previous assumptions. This helped shift the focus from a linear progression of human evolution to a more complex, branching family tree of human ancestors.

The Leakeys' discoveries in Africa, particularly at sites like Olduvai Gorge, provided crucial evidence of early hominid fossils and tools, fundamentally reshaping our understanding of human origins. Their work highlighted the significance of Africa as the "Cradle of Humanity," suggesting that modern humans evolved from ancestral species in this region. This research emphasized the complexity of human evolution, illustrating how various hominids adapted and thrived in diverse environments. Overall, the Leakeys' contributions underscored the importance of fossil evidence in tracing the evolutionary journey of humans.
This is a very old observation, from the prehistoric times.
It is necessary for a discovery to be well publicized within society. This will allow that discovery to bring about the most extensive social change.
Mainly size is what changed from prehistoric times to today.
