The Variation of Animals and Plants under Domestication — Volume 1

by Charles Darwin

"The Variation of Animals and Plants under Domestication — Volume 1" by Charles Darwin is a scientific work published in January 1868. This extensive study examines how animals and plants change through selective breeding and domestication. Darwin presents detailed observations from years of experiments and correspondence with breeders worldwide. The book also introduces his controversial theory of heredity called pangenesis. Written over four years of intense labor, this work represents Darwin's attempt to provide the factual foundation promised in "On the Origin of Species," though he privately worried about its reception.
