Making Babies sets the latest findings in reproductive biology in a challenging evolutionary, historical, and sociological context, proving that, when it comes to drama, pregnancy has it all: sibling rivalry, a battle of the sexes, and a crisis of gender indentity. Along the way, Bainbridge revisits some of the key puzzles about pregnancy: What's sex got to do with it? How does the fetus hijack its mother's immune system? What is the point, if any, of morning sickness? Just how does a fertilized ovum develop into eight pounds or so of baby, with ten fingers and ten toes? Does the baby or the mother control the onset of labor, and why is it such an ordeal for them both?" "Entertaining and informative, Making Babies shows how the study of human pregnancy can help us understand both our genesis as individuals and our evolution as a species, and provides insight into who we are and why we behave as we do.
