Grouping evolves in patchy environments. I-V: patch classes, going from uniform to increasing patchiness (see model description). Left: 1 by 0.2 km snap shots of the environments illustrating resource distributions. The more yellow the greater the density of resources; Right: Group size evolution for each of 10 simulations in each environment. Black: no grouping evolves; Orange: groups of 2-3 individuals evolve; Blue: groups size evolves to half way between solitary and small groups. Values in brackets indicate the number of simulations ending up in a particular condition.
