Abstract
Michael Scriven’s example of the identical twins who do unequally well in the project of surviving and reproducing has long occupied a central place in the philosophy of biology literature on fitness and natural selection. In Scriven’s story, you are asked to imagine that the twins have identical genotypes and phenotypes, and live in the same environment. One of them is childless and is killed by lightning, while the other isn’t hit by the lightning and goes on to have some offspring. The philosophical lesson drawn from this example can be encapsulated in a simple argument
