Darwin, and after Darwin

This three-volume study by George John Romanes explores the implications of Darwin's theories, particularly focusing on physiological selection and isolation.

Written by evolutionary biologist George John Romanes, Darwin, and after Darwin is a comprehensive three-volume exploration of Charles Darwin's theories on evolution by natural selection. Published posthumously in 1897, this work delves into the implications of Darwin's ideas and examines the various factors that contribute to evolutionary change. Romanes, a close friend of Darwin, sought to expand upon the foundational concepts of natural selection, presenting his own insights on physiological selection and its role in evolution.

In the third volume of Darwin, and after Darwin, Romanes addresses the 'post-Darwinian question' of isolation, challenging the traditional view that geographical barriers are the primary drivers of evolutionary divergence. Instead, he posits that physiological differences within species are equally, if not more, significant in shaping evolutionary outcomes. This perspective adds a new dimension to the understanding of evolution, reflecting Romanes' commitment to advancing the dialogue surrounding Darwinian theory.

Romanes' work is notable not only for its scientific content but also for its historical context. As a prominent supporter of Darwin's ideas in the late 19th century, Romanes contributed to the broader acceptance of evolutionary biology. His lectures, which served as the foundation for this three-volume study, were delivered in prominent venues in Edinburgh and London, showcasing the growing interest in evolutionary thought during this period. Darwin, and after Darwin remains a significant contribution to the field of evolutionary biology.
