title: The dark side of evolution: caprice, deceit, redundancy.
abstract: The prevalent reading of Darwin's achievements today is adaptationist. Darwin, so the usual story goes, succeeded in providing a naturalistic explanation of the fact that organisms are adapted to their environments, a fact that served and continues to serve, as a chief argument for creationism. This stands in a curious tension with Darwin's own fascination with phenomena whose adaptive value was problematic, like vicariance, ornaments, atavisms, and rudiments, as well as the various "contraptions" and "contrivances" by which organisms take advantage of each other. I will explore this "dark side" of Darwin's evolutionism with respect to three themes that run through his work: heredity, which provided one of the corner stones of Darwin's theory and yet was defined as an essentially capricious, not necessarily adaptive force; mimicry, which for Darwin exemplified a general tendency of nature to produce deceiving semblances that turn actual relations on their head; and extinction, a phenomenon that pointed towards the redundancy of life, which for Darwin, in the double sense of that word, was both a fundamental condition and necessary consequence of evolution by natural selection.
