A methodology is described for designing real-time animated artificial life worlds consisting of populations of physically-based articulated creatures which evolve locomotion anatomy and motion over time. In this scheme, increasing levels of emergent behavior are enabled by designing more autonomy into the simulation on progressively deeper levels. A set of simulations are discussed to illustrate how this methodology was developed, with the most recent simulation demonstrating the effects of mate choice on the evolution of anatomies and motions in swimming creatures.
