"Extraordinary . . . This inspirational autobiography stands among the finest scientist memoirs."
—New York Times Book Review, Editors' Choice
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.
"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 ape-like 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."

“An exciting and richly informative scientist’s autobiography…This major work of scientific dedication and original insight illuminates both our distant past and our current, serious, human-caused planetary challenges.”
—Booklist Review *starred*
“Attentive readers of Meave Leakey’s masterful memoir, The Sediments of Time, will learn a few details about her personal life....But the main and most illuminating parts of [the book] are about the tedious, painstaking years spent hunting for the fossilized remains of our species’ precursors. Drawing on field notes, interviews and research papers, Meave recounts the work that led to some of her and her team’s greatest discoveries....Meave and her co-writer, her youngest daughter Samira Leakey, write clearly and compellingly about what these discoveries mean...A thrilling account.”
"For over 50 years, British-born palaeoanthropologist Meave Leakey has been unearthing fossils of our early ancestors in Kenya’s Turkana Basin. Her discoveries have changed how we think about our origins. Instead of a tidy ape-to-human progression, her work suggests different pre-human species living simultaneously. Leakey’s new memoir, The Sediments of Time: My Lifelong Search for the Past, co-written with her daughter Samira, reflects on her life in science and pieces together what we now understand about the climate-driven evolution of our species."
“An engaging memoir...A marvelous account of what it is like for a celebrated scientist to take on some of the most vital and vexing questions regarding human origins and to come up with biocultural answers.”
“Meave describes a life that many readers will envy. Her discoveries, often after numbingly tedious work in a brutal climate, added new species to our family tree, teased out more information about existing ancestors, and increased our knowledge of how evolution, geology, and climate change gave rise to modern humans. She is not shy about explaining all this....An illuminating memoir of an impressive scientist.”
"Fossils, hyaenas, and eccentric scientists almost literally jump off the page in Meave Leakey's exuberant memoir. This riveting read takes you on the unplanned but glorious adventure that has been Meave's life of discovery. Her love of learning and quest for knowledge about our origins inspire every page and will set your mind alight!"

“Meave Leakey confronts extraordinary challenges that ultimately yield unimaginably rich rewards. THE SEDIMENTS OF TIME offers everything for everyone: exciting fossil finds, courageous expeditions, seminal paleoanthropological contributions to science, and convincing scientific evidence to support climate change. Meave has labored five decades filling the gaps in Homo sapien’s 3+ million year journey of evolution. She also verifies global climate change by analyzing fossil teeth, 800,000 year old ocean floor ice cores, and Milankovitch’s sun-earth alignment to explain global glaciation and torrid periods. She is a researcher extraordinaire."
