In his latest book, David Bainbridge combines an otherworldly journey through the central nervous system with an accessible and entertaining account of how the brain's anatomy has often misled anatomists about its function. Bainbridge uses the structure of the brain to set his book apart from the many volumes that focus on brain function. He shows that for hundreds of years, natural philosophers have been interested in the gray matter inside our skulls, but all they had to go on was its structure. Almost every knob, protrusion, canal, and crease was named before anyone had an inkling of what it did--a kind of biological terra incognita with many weird and wonderful names: the zonules of Zinn, the obex ("the most Scrabble-friendly word in all of neuroanatomy"), the aqueduct of Sylvius, the tract of Goll.

This uniquely accessible approach lays out what is known about the brain (its structure), what we can hope to know (its function), and what we may never know (its evolution). Along the way Bainbridge tells lots of wonderful stories about the "two pounds of blancmange" within our skulls, and tells them all with wit and style.

Drawing on past speculation and present knowledge, reproductive biologist David Bainbridge conducts us through the forty weeks of a human pregnancy, from conception to breastfeeding, explaining the complex biology behind human gestation in a clear and unassuming manner.

Making Babies sets the latest findings in pregnancy 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 identity. 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 our genesis as individuals and our evolution as a species, and provide insight into who we are and why we behave as we do.

A tiny scrap of genetic information determines our sex; it also consigns many of us to a life of disease, directs or disrupts the everyday working of our bodies, and forces women to live as genetic chimeras. The culprit--so necessary and yet the source of such upheaval--is the X chromosome, and this is its story. An enlightening and entertaining tour of the cultural and natural history of this intriguing member of the genome, The X in Sex traces the journey toward our current understanding of the nature of X. From its chance discovery in the nineteenth century to the promise and implications of ongoing research, David Bainbridge shows how the X evolved and where it and its counterpart Y are going, how it helps assign developing human babies their sex--and maybe even their sexuality--and how it affects our lives in infinitely complex and subtle ways. X offers cures for disease, challenges our cultural, ethical, and scientific assumptions about maleness and femaleness, and has even reshaped our views of human evolution and human nature.
