"Studies in the Theory of Descent, Volume I" by August Weismann is a scientific exploration into the world of evolution, specifically examining how external factors drive physical changes in species. The study hones in on seasonal dimorphism, a concept vividly displayed by the butterfly *Araschnia Levana*, which manifests differently in summer versus winter. Weismann shares his experiments, designed to reveal if these seasonal differences are caused by environmental conditions or fundamental biological adaptations, and, in that, looks to solve the mysteries of evolutionary change.
