Life, Reproduction, and the Paradox of Evolution

A neglected but challenging argument developed by Peter Geach, John Haldane, and Stephen Rothman purports to show that reproduction cannot be explained by natural selection and is irreducibly teleological. Meanwhile, the most plausible definitions of life include reproduction as a constitutive feature. The implication of combining these ideas is that life cannot be explained by natural selection and is irreducibly teleological. This does not entail that life cannot be explained in evolutionary terms of some kind, but it does lend support to the controversial view of Jerry Fodor and Thomas Nagel that evolutionists need to look beyond the constraints of Neo-Darwinism.
