The book gathers Henry de Varigny’s 1891 lectures on Experimental Evolution, arguing that proof of evolution requires direct, observable experiments.
It blends scientific history with practical methods to test how living things change under real-world conditions.
Readers will see how environment, domestication, plant and animal cultivation, and physiological differences reveal the malleability of life. The text emphasizes a shift toward experimental verification as a path to advance the theory of evolution.
- How variation arises and expresses itself across species, ages, and environments
- Methods for long-term experiments that test change in plants and animals
- Connections between historical French and broader scientific views on evolution
- Practical considerations for running farm and laboratory experiments that last decades
Ideal for readers curious about the history and practical testing of evolutionary ideas.
