Technology pervades our daily lives and modern society, and not just when it comes to computers and smart phones. Before there was the computer, there was the abacus. Before the smart phone, there was the telegraph and ball point pen. Electricity, penicillin and the compass have all led to revolutionary changes in how we live. The Handy Technology Answer Book explains how technology has revolutionised the way people live, work and play. It covers a broad range fields, including medicine, mining, buildings and transportation.

In most animals, from bees to bulls, mice to men, it is possible to see at a glance whether an individual is male or female. How and why these differences in appearance and behavior developed and the nature and extent of the differences between males and females is a complex subject. This book reviews the latest molecular, genetic, hormonal, anatomical, and behavioral data in a wide range of species in a series of lively and highly readable articles from the world's leading experts in this field. Unashamedly Darwinian, this book brings sexual selection up to date and discusses not only a dazzling array of differences between the sexes, but probes the mechanisms by which they are produced and the adaptive significance of the differences themselves. It should have a wide appeal, especially to undergraduates and graduates in the biological and medical sciences, and should help to bridge the gap between those who study genes and molecules in the laboratory and those who study the behavior of animals in the wild.
