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. » —Jane Goodall, PhD, DBE, Founder of the Jane Goodall Institute
“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 starred review

Even as millions of Americans suspect they’re suffering from a gastrointestinal disorder, they may spend years in pain before they figure out just what’s going on with their gut. And while irritable bowel syndrome (IBS) is commonly diagnosed, SIBO, a disorder with basically all the same symptoms, is not. So, what is SIBO? The acronym stands for Small Intestine Bacterial Overgrowth, a disorder in which bacteria that usually grow in other parts of the gut start to proliferate and take up residence in the small intestine. This causes a whole confluence of symptoms, ranging from bloating and cramps, to uncontrollable weight gain or weight loss, to even malnutrition when the bacteria eat up vital nutrients from our food. Even though several studies have shown that as many as 84 percent of patients with IBS also tested positive for SIBO, it remains understudied and underdiagnosed. After decades of dealing with debilitating symptoms with no relief, Shivan Sarna’s life changed when she was diagnosed with SIBO. As she eliminated her symptoms one by one through lifestyle changes and help from her physicians, she started to synthesize her personal experiences with Western and naturopathic medicine and dedicate herself to advocating for those suffering from SIBO, or those who think they could be.
In this compelling follow-up to the national bestseller The Rise of Wolf 8, Rick McIntyre profiles one of Yellowstone’s most revered alpha males, Wolf 21. Leader of the Druid Peak Pack, Wolf 21 was known for his unwavering bravery, his unusual benevolence (unlike other alphas, he never killed defeated rival males), and his fierce commitment to his mate, the formidable Wolf 42. Wolf 21 and Wolf 42 were attracted to each other the moment they met—but Wolf 42’s jealous sister interfered viciously in their relationship. After an explosive insurrection within the pack, the two wolves came together at last as leaders of the Druid Peak Pack, which dominated the park for more than 10 years. McIntyre recounts the pack’s fascinating saga with compassion and a keen eye for detail, drawing on his many years of experience observing Yellowstone wolves in the wild. His outstanding work of science writing offers unparalleled insight into wolf behavior and Yellowstone’s famed wolf reintroduction project. It also offers a love story for the ages.
