Darwin's Backyard: How Small Experiments Led to a Big Theory

Most readers will be surprised to learn of the incredible amount of field research, observation, and experimentation that Charles Darwin did in the many years after his famous voyage. Costa (biology, Western Carolina Univ.; Wallace, Darwin, and the Origin of Species) argues that those experiments are not only foundational but also educational: they explain evolution better than any classroom lecture. To that end, each chapter focuses on a different obsession of Darwin's, from orchids to seed migration, and is followed by an experiment that demonstrates a principle of evolution. These examples are of the quick and simple variety, and a well-equipped high school science class could perform them easily. Costa's secondary goal is to place Darwin in the context of his family and friends, many of whom he deputized to help with his observations; in this, the author is less successful. Although there are frequent mentions of Darwin's children, only rarely do their own voices or inclinations shine through.
