James T. Costa takes readers on a journey from Charles Darwin’s youth and travels on the HMS Beagle to Down House, his bustling home of forty years. To test his insights into evolution, Darwin devised experiments using his garden and greenhouse, the surrounding land and his home-turned-field-station. His experiments yielded universal truths about nature and evidence for his revolutionary arguments in On the Origin of Species and other watershed works. We accompany Darwin in his myriad pursuits against the backdrop of his enduring marriage, chronic illness, grief at the loss of three children and joy in scientific revelation. At each chapter’s end, Costa shows how we can investigate the wonders of nature, with directions on how to re-create Darwin’s experiments.
