Genetic Architecture Promotes the Evolution and Maintenance of Cooperation

Figure 1

Cheater invasion dynamics in phenotypically similar starting populations.

In the main figure each line represents the average secretion, over time, of replicate populations started from the same ancestor. For clarity, we did not include the standard error of each group of replicate populations. The insert figure shows all replicate populations for the two most extreme population groups, zoomed in on the time period of interest for our analyses. Specifically, of all the population groups sharing a common ancestor, the blue populations had the highest and red the lowest average secretion between generation and generation . Note that average secretion in the inset represents the average secretion within each population, whilst in the main figure it is the average of the secretion of all the individuals from the replicate populations that share the same ancestor.
