Meave Leakey's thrilling, high-stakes memoir--written with her daughter Samira--encapsulates her distinguished life and career on the front lines of the hunt for our human origins, a quest made all the more notable by her stature as a woman in a highly competitive, male-dominated field. In The Sediments of Time , preeminent paleoanthropologist Meave Leakey brings us along on her remarkable journey to reveal the diversity of our early pre-human ancestors and how past climate change drove their evolution. She offers a fresh account of our past, as recent breakthroughs have allowed new analysis of her team's fossil findings and vastly expanded our understanding of our ancestors. Meave's own personal story is replete with drama, from thrilling discoveries on the shores of Lake Turkana to run-ins with armed herders and every manner of wildlife, to raising her children and supporting her renowned paleoanthropologist husband Richard Leakey's ambitions amidst social and political strife in Kenya. When Richard needs a kidney, Meave provides him with hers, and when he asks her to assume the reins of their field expeditions after he loses both legs in a plane crash, the result of likely sabotage, Meave steps in. The Sediments of Time is the summation of a lifetime of Meave Leakey's efforts; it is a compelling picture of our human origins and climate change, as well as a high-stakes story of ambition, struggle, and hope.
