2. She collaborated with her husband, Louis Leakey, on numerous excavations, significantly contributing to the understanding of early human evolution.
3. Her work helped establish East Africa as a crucial area for paleoanthropological research, yielding numerous fossils and artifacts that shaped the narrative of human origins.
4. Mary Leakey also played a significant role in developing methods for the excavation and analysis of ancient sites, paving the way for future researchers in the field.
5. In recognition of her contributions, she received numerous awards and honors, including being named a Fellow of the Royal Society in 1979.

Review Questions

• What were some of the key discoveries made by Mary Leakey at Olduvai Gorge, and why are they important?
  • Mary Leakey's discoveries at Olduvai Gorge included significant hominid fossils and stone tools that provided insight into early human behavior and evolution. Among her most notable finds were the remains of Paranthropus boisei and Homo habilis. These findings helped to demonstrate the variety of early hominids that existed and their adaptations over time, which are crucial for understanding the evolutionary lineage leading to modern humans.
• Discuss the impact of Mary Leakey's discovery of the Laetoli footprints on our understanding of early hominid locomotion.
  • The discovery of the Laetoli footprints by Mary Leakey was groundbreaking as it provided clear evidence that early hominids were walking upright much earlier than previously believed. The footprints, preserved in volcanic ash, showed bipedalism around 3.6 million years ago, suggesting that this trait evolved significantly earlier in our evolutionary history. This finding reshaped scientific discussions about how and when upright walking developed in relation to other adaptations in early hominids.
• Evaluate how Mary Leakey's work has influenced modern paleoanthropology and the study of human evolution.
  • Mary Leakey's work has profoundly influenced modern paleoanthropology by establishing rigorous excavation techniques and interdisciplinary approaches that combined geology, archaeology, and biology. Her discoveries have underscored the significance of East Africa as a key area for studying human origins, prompting further research in the region. Additionally, her contributions continue to inform current understandings of human evolution, highlighting the complexities of our ancestry and the adaptive strategies employed by early hominids in response to environmental changes.
