Darwin's Proposal and Its Rejection
Darwin introduced the theory of sexual selection as a distinct process from natural selection, emphasizing that mate choice could significantly impact evolution. During his lifetime, this idea was largely rejected by contemporaries, who viewed female choice as a trivial concept. Critics believed that attributing aesthetics to female agency was unfounded, and this view isolated Darwin within his scientific community. Despite these challenges, he argued that selective mating behaviors led to notable evolutionary changes in male traits, a point that remained controversial even among his supporters.
