Overview

After the publication of On the Origin of Species in 1859 Darwin became fascinated with the potential for botanical experiments to provide evidence for the process of evolution. First published in 1877, this volume is based on a series of papers concerning heterostylous plants (species which produce different types of flowers) originally published in the Journal of the Proceedings of the Linnaen Society in 1862. Linnaeus had divided the sexual relations of flowers into four groups, which Darwin uses as the structure for this volume. Darwin examines in detail plants which produce different flower forms, presenting his conclusions in terms of adaptive evolution and so providing the first functional interpretation of heterostyly. He demonstrates that these plants are adapted for cross-fertilisation, not self-fertilisation as was widely believed. The concepts which Darwin introduces in this volume continue to provide the basis for research into plant reproductive biology.

About the Author

About The Author
Charles Robert Darwin, FRS FRGS FLS FZS (12 February 1809 - 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. He established that all species of life have descended over time from common ancestors and, in a joint publication with Alfred Russel Wallace, introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.
