How does space alter the formulation of evolutionary models?
Whigham, Peter A; Dick, Grant
This short paper discusses how space is introduced within evolutionary models and reviews several approaches from the literature. In particular, the Moran process is used as one type of model that has been described in several ways when space is introduced. The evolutionary operations of parental selection, offspring placement, synchronous and asynchronous updating, survival and death timings are shown to be factors that may be interpreted in a number of ways once space is introduced into a model. One conclusion from this discussion is that the introduction of space requires a consideration of the time-step in models, directly through event driven processes or indirectly through the random selection of space prior to a local process.
