The Sediments of Time

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 prehuman 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 personal story is replete with drama, from thrilling discoveries on the shores of Lake Turkana—including the 3.5-million-year-old skull of the flat-faced man from Kenya, representing an important new branch of the human family—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, 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.

“A fascinating glimpse into our origins. Meave Leakey is a great storyteller, and she presents new information about the far-off time when we emerged from our apelike ancestors to start the long journey that has led to our becoming the dominant species on Earth. That story, woven into her own journey of research and discovery, gives us a book that is informative and captivating, one that you will not forget.”
