Sarah Blaffer Hrdy is professor emerita of anthropology at the University of California, Davis. She is the author of The Woman That Never Evolved, Mother Nature, and Mothers and Others: The Evolutionary Origins of Mutual Understanding.

"Nothing short of a brilliant tour de force, an instant classic and an unparalleled ‘must read’ for anyone with even a mild personal and/or professional interest in parenting, gender roles/relations, the wellbeing of society and the prospects and choices facing human beings right now, as well as in the future." --- "Profound in its insights, Father Time is an anthropological take on the biological and cultural transformations of fatherhood over time. At the heart of the work.... is the fundamental question of what it means to be a man. Father Time is an intensively researched book that doesn’t sacrifice engagement or intrigue." --- "[I] loved...Father Time...by brilliant evolutionary anthropologist Sarah Blaffer Hrdy, about the long history of male nurturing."---Tessa Hadley, Daily Express --- "In her excellent book Father Time: A Natural History of Men and Babies, anthropologist and primatologist Sarah Blaffer Hrdy . . . explores the question of whether male nurturing and care for the next generation is biologically pre-programmed and possible across a whole range of species in the animal kingdom, and, if so, what this might mean not only for human parental roles, but also for society itself."---Sarah Hawkes, The Lancet --- "Why have biologists so neglected fatherhood? Thus begins a profound new study from Hrdy, widely seen as one of evolutionary biology’s most important thinkers since Darwin. With smoothness and authority, she demolishes old ideas of essential differences between the sexes, and shows how social change is liberating men’s desire to be child-carers." --- "Hrdy has over a long and much-decorated career insisted that, if we want to understand how our species came to be, we need to understand what happened in the dim reaches of our prehistory around babies, mothers and ‘alloparental others’. . . . In chasing after evolutionary levers beyond the usual Darwinian gaze (historically focused on male competition), she has not only helped to create new narratives about what ‘nature’ is, and how we came to be, but also changed the questions younger cohorts of researchers think to ask. . . . [Father Time] reads like a detective story – and [Hrdy] herself is as colourful as Sherlock Holmes."---Michele Pridmore-Brown, Times Literary Supplement --- "Father Time.... picks up where Mother Nature and Mothers and Others left off. [Hrdy's] interest lies in how external forces shape what’s happening inside our bodies, and vice versa. She contends that the emergence of more egalitarian norms of parenthood aren't just changing society; they could change the biochemical makeup of men, too."---Hua Hsu, The New Yorker --- "Evolutionary anthropologist Hrdy sets out to demolish the still prevalent view that, with the exception of lactation and breastfeeding, women are better suited than men to nurture babies and bring up infants. She employs cultural and scientific arguments going deep into mammalian evolution to show that, given the opportunity, the male biological response to babies is virtually the same as the female."---Clive Cookson, Financial Times --- "[A] detailed book. . . . [With] thought-provoking questions. . . . A fascinating read. . . . [Hrdy] makes a convincing and persuasive argument."---Glenda Cooper, Daily Mail --- "When a scientist of Hrdy's caliber gets curious about something, a deep dive into multifaceted research begins. In [Father Time], she traces the origins of male nurturing across vertebrate, mammalian, primate, and hominid evolution, up to our current moment in history. Along the way, the reader learns about reproductive strategies in various creatures, including the poison dart frog, the cassowary, the meerkat, and the titi monkey, as well as our Homo sapiens selves.... The reading is so nutrient-rich that you will want to pause, digest, reflect, delight, and then urgently read on"---Claudia Casper, Los Angeles Review of Books --- "A mesmerizing, masterfully written book on the transformative power of human parenting" --- "An outstanding examination of the history and science of fatherhood.... Revelatory scientific studies shedding light on men’s biological proclivity for caring...complement the edifying history. It amounts to an invaluable deep history of dads." --- "I love how Hrdy sweeps across thousands of millennia, and dozens of species. I love how she convinces us, given that widespread and million-year legacy, and given that most of all the way contemporary Aka, Hadza, and American fathers are behaving, H. sap males manifestly can parent as well as females. And I love how Hrdy weaves so much of that narrative into her personal story."---Laura Betzig, Psychology Today --- "A rich journey for the reader that not only provides a greater understanding of the evolution of fatherhood but also demonstrates how...the researcher’s personal experiences...can spawn new perspectives and insights....This is a remarkable book, filled with detailed scientific information, expert interpretations of the data, and a brilliant narrative voice."---Richard Bribiescas, Harvard Magazine --- "Both cultural norms and evolutionary science have long held that caring for babies is primarily the woman’s domain. But when the anthropologist Sarah Blaffer Hrdy noticed that the role of fathers was changing, her research led her to discover the profound biological and social implications of a nurturing masculinity." --- "[Sarah Blaffer Hrdy] is a rare science writer who combines mastery of her field with warm, readable prose. . . . Her life’s work has been to reinvent the way we think about ourselves, and to disentangle gender myths from the more flexible truths about human behaviour."---Sarah Ditum, Sunday Times --- "I turned to [Father Time] seeking validation and found something much better: the complete destabilization of my concept of paternity."---Dan Piepenbring, Harper's Magazine --- "Hrdy’s writing is a joy to read. . . . Father Time will be valued by anyone interested in male care of infants and children. Hrdy’s broad, accessible writing will appeal to non-scientists, but her peers will appreciate her summary of current research on the hormonal and neurobiological aspects of male care. As a biological anthropologist focused on fatherhood and men’s investments in children, I certainly learnt a great deal."---Kermyt G. Anderson, Nature --- "Father Time will change minds, but more importantly, it points the way to a different type of science, one that takes into account how culture shapes biology and doesn’t stand apart from it. . . . Hrdy is, without exaggeration, one of the most important thinkers in evolutionary biology since Darwin . . . Her beautiful writing retains as much power to astound and educate as ever."---Angela Saini, Telegraph --- "Winner of the PROSE Award in Biological Anthropology, Archeology and Ancient History, Association of American Publishers" --- "A New Statesman Best Book of the Academic Presses" --- "Longlisted for the PEN/E.O. Wilson Literary Science Writing Award, PEN America"
