Are animals altruistic? Why does the heart beat? What do the smallest microbe and the largest mammal have in common?

These are just some of the thought-provoking questions addressed in this richly illustrated book. Join authors Michael C. Gerald and Gloria E. Gerald as they explore 250 of the most important and interesting milestones in biology, starting from approximately 4 billion years ago and reaching the modern era.
In addition to amazing mysteries and wonders, such as mummification and "living fossils" like the coelacanth, a wide range of topics are covered, including agriculture, animal migration, natural selection, nature versus nurture, the microbial theory of disease, and more.

It also features great scientists and other prominent figures, such as Aristotle, William Harvey, Charles Darwin, Claude Bernard, Rachel Carson, James Watson, and Francis Crick.

The "Milestones of Science" series is a highly original encyclopedia that vividly captures the course of scientific thought and practice throughout the centuries. Beyond the historical overview, which focuses on the most significant milestones in the long history of scientific evolution, the series also presents a spectacular panorama of the sciences. Each book is written by expert researchers, scientists, and writers in a language that is understandable, and each entry is accompanied by stunning full-page photographs.
