Group-selection via aggregative propagule-formation enables cooperative multicellularity in an individual based, spatial model

Possible reproduction mechanisms considered for the population when a new habitat is colonized.
During selection for colonization (transfer), cells are either selected randomly (B, C, D) or based on strongest aggregate (E, F). After transfer to the new habitat, the population either retains its original structure (D, F) or is dispersed (B, E). For more details, see text. The labels A-F are used consistently in all figures.
