How We Do It


Book Description

Despite the widespread belief that natural is better when it comes to sex, pregnancy, and parenting, most of us have no idea what "natural" really means; the origins of our reproductive lives remain a mystery. Why are a quarter of a billion sperm cells needed to fertilize one egg? Are women really fertile for only a few days each month? How long should babies be breast-fed? In How We Do It, primatologist Robert Martin draws on forty years of research to locate the roots of everything from our sex cells to the way we care for newborns. He examines the procreative history of humans as well as that of our primate kin to reveal what's really natural when it comes to making and raising babies, and distinguish which behaviors we ought to continue -- and which we should not. Although it's not realistic to raise our children like our ancestors did, Martin's investigation reveals surprising consequences of -- and suggests ways to improve upon -- the way we do things now. For instance, he explains why choosing a midwife rather than an obstetrician may have a greater impact than we think on our birthing experience, examines the advantages of breast-feeding for both mothers and babies, and suggests why babies may be ready for toilet training far earlier than is commonly practiced. How We Do It offers much-needed context for our reproductive and child-rearing practices, and shows that once we understand our evolutionary past, we can consider what worked, what didn't't, and what it all means for the future of our species.










An Illustrated Guide to Human Reproduction and Fertility Control


Book Description

This is a large-format colour-illustrated guide to human reproduction, best described by the authors themselves: "This book offers accessible information about the anatomy of men and women, the physiological steps that lead to conception and gestation and birth, and the means we have to control these events. We hope that high school and college students, young adults, men and women facing decisions about fertility, and the clinicians who care for them will use this book's illustrations and text to pierce the mystery and misinformation that sometimes surrounds these issues. By taking readers step-by-step through the development of egg and sperm, fertilization, implantation, embryonic and fetal growth, and birth as well as methods of birth control, termination of pregnancy, treatment for infertile couples, and menopause, this book hopes to contribute to both the knowledge and the awe that surround human reproduction."




On Fertile Ground


Book Description

Reproduction is among the most basic of human biological functions, both for our distant ancestors and for ourselves, whether we live on the plains of Africa or in North American suburbs. Our reproductive biology unites us as a species, but it has also been an important engine of our evolution. In the way our bodies function today we can see both the imprint of our formative past and implications for our future. It is the infinitely subtle and endlessly dramatic story of human reproduction and its evolutionary context that Peter T. Ellison tells in On Fertile Ground. Ranging from the latest achievements of modern fertility clinics to the lives of subsistence farmers in the rain forests of Africa, this book offers both a remarkably broad and a minutely detailed exploration of human reproduction. Ellison, a leading pioneer in the field, combines the perspectives of anthropology, stressing the range and variation of human experience; ecology, sensitive to the two-way interactions between humans and their environments; and evolutionary biology, emphasizing a functional understanding of human reproductive biology and its role in our evolutionary history. Whether contrasting female athletes missing their periods and male athletes using anabolic steroids with Polish farm women and hunter-gatherers in Paraguay, or exploring the intricate choreography of an implanting embryo or of a nursing mother and her child, On Fertile Ground advances a rich and deeply satisfying explanation of the mechanisms by which we reproduce and the evolutionary forces behind their design.
