The Variation of Animals and Plants under Domestication

Drawing on a remarkable collection of sketches and measurements, this work examines the striking diversity that human hands have coaxed from domestic species. From striped Devonshire ponies to the myriad forms of pigeons, rabbits, and fowls, each illustration is paired with careful description of skeletal and anatomical differences, revealing how selective breeding highlights the mechanisms first outlined in the earlier theory of natural selection.

The author situates these observations within a broader argument that the same forces shaping wild life also operate in farms and gardens. By cataloguing the subtle and dramatic changes in animals such as pigs, rabbits, and birds, as well as in cultivated plants like peas and stone fruits, the book offers concrete evidence that variation is not random but can be directed over generations. Listeners gain insight into the early scientific effort to link everyday breeding practices with the grander picture of evolution.
