Darwin's Unfinished Big Book and Its Implications

The chapter explores Darwin's shift from working on a follow-up book to publishing a monograph on orchids, perceived as an attempt to provide evidence for natural selection but interpreted by some as supporting design. It delves into the disappointment among Darwin's correspondents due to the incomplete promised comprehensive book and examines Stephen J. Gould's insights on the necessity of the second book. The speakers highlight the weaknesses of Darwin's unfinished big book from 1975 in providing substantial evidence for natural selection, exploring how his analogy between natural and artificial selection affects the argument for evolution.
