Ecological specialization and adaptive decay in digital organisms.

The American naturalist - 1 Jan 2007

Ostrowski Elizabeth A, Ofria Charles, Lenski Richard E

Abstract excerpt

The transition from generalist to specialist may entail the loss of unused traits or abilities, resulting in narrow niche breadth. Here we examine the process of specialization in digital organisms--self-replicating computer programs that mutate, adapt, and evolve. Digital organisms obtain energy by performing computations with numbers they input from their environment. We examined the evolutionary trajectory of...
