A series of accessible natural-history essays for a wide audience, ranging from personal field observations of marine and shore life to broader discussions of birds, insects, and mammals; chapters examine anatomical and evolutionary comparisons between apes and humans, account for courting and display behaviors, trace the curious history of barnacles and folk beliefs, and treat practical subjects such as forestry, milk supply, circulation, and scientific method. Illustrated plates and clear examples accompany reflections on how science enriches perception, blending lively description, specimen-based explanation, and skeptical attention to myths and dubious claims.
