Here is a brief and authoritative account of human physical growth, beautifully written by one of the world's foremost experts. In Fetus into Man Professor Tanner tells the story of growth in language that is both accessible to the nonbiologist and acceptable to the biologist.

The book begins with the basics of growth: cell division, hormonal control and differential growth of body tissues. It then builds on these basics to provide a picture of individual growth--from the fetus in utero to the development of sex differences at puberty. Tanner pays special attention along the way to the psychological and social problems faced by children who mature either too soon or too late, and he concludes with a full description of the major growth disorders and current methods of treatment.

Fetus into Man will be an important reference for parents, educators, students of development, and indeed anyone who must deal with the growing child.

The strike of a praying mantis's forelegs is so fast that, once they are set in motion, the mantis cannot control its aim. How does it ever manage to catch a fly? A moth negotiating the night air hears the squeak of a hunting bat on the wing, and tumbles out of harm's way. How?

Insects are ideal subjects for neurophysiological studies, and at its simplest level this classic book relates the activities of nerve cells to the activities of insects, something that had never been attempted when the book first appeared in 1963. In several elegant experiments--on the moth, the cockroach, and the praying mantis--Roeder shows how stimulus and behavior are related through the nervous system and suggests that the insect brain appears to control behavior by determining which of the various built-in activity patterns will appear in a given situation. This slim volume remains invaluable to an understanding of the nervous mechanisms responsible for insect behavior.
