Darwin, and After Darwin, Volume 3 of 3 Post-Darwinian Questions: Isolation and Physiological Selection

This volume concludes a thoughtful three‑part exploration of Darwin’s legacy, turning the spotlight on the often‑overlooked forces that shape life’s diversity. Edited by a respected scholar, the text brings together the final chapters left unfinished at the author’s death, preserving his original voice while offering careful arrangement of his notes and correspondence.

The central theme is “isolation” – the way separated populations cease interbreeding, whether by geography, migration or other barriers. The author argues that this principle stands alongside heredity and variation as a foundational pillar of evolution, even rivaling natural selection in depth. He also introduces physiological selection, showing how internal bodily adaptations can drive change. Richly illustrated and grounded in the practical observations of breeders and naturalists, the work invites listeners to glimpse a pivotal moment when early 20th‑century scientists re‑examined the mechanisms behind the living world.
