The Variation of Animals and Plants under Domestication — Volume 2

"The Variation of Animals and Plants under Domestication — Volume 2" by Charles Darwin is a scientific publication from the late 19th century. This volume continues Darwin's exploration of how domestication affects the variation and inheritance of traits in animals and plants, delving deep into concepts such as reversion, inheritance, and the effects of crossing breeds. At the start of this volume, Darwin introduces the principle of inheritance and the phenomenon of reversion or atavism, where traits from distant ancestors reappear in descendants. He discusses various examples of reversion in both animals and plants, illustrating how certain characteristics can emerge again after being lost over generations. The opening section provides insights into the mechanics of inheritance, examining how traits that were once common may lie dormant and later manifest, revealing the complexities of genetic transmission and the potential historical connections within domesticated species.
