A Case Study of the De Novo Evolution of a Complex Odometric Behavior in Digital Organisms
(A) Modified ancestral left-turn path, with extended path end. The organism successfully travels the entire path, stepping exactly one cell off the end and then stopping. (B) Modified ancestral right-turn path, with extended path end. The organism turns and retraces its steps before reaching the path end. (C) Unfamiliar left-turn path. The organism turns incorrectly at the first turn. The organism neither traverses the path nor replicates in this environment. (D) Unfamiliar long right-turn path. The organism traverses the entire path but fails to self-replicate.
