The Variation of Animals and Plants under Domestication Part Two

In this second part of a two-volume work, Darwin explores the transformations of domesticated animals and cultivated plants under human influence. He focuses on various aspects of inheritance, variation, and the effects of domestication, including the principles of crossing and hybridism. Key themes include the impact of environmental changes on species and the role of selection by humans. The text aims to provide insights into the nature of variation and the laws governing it, culminating in a provisional hypothesis on pangenesis.
