“#New insights revealed in the evolution of community-level heredity” Communities founded with an equal ratio of red-to-blue cells are assessed after a round of cell growth. Communities far from the optimal pink colour (1:1 ratio) are eliminated, whereas those close to the optimum are selected to leave offspring communities. Stochastic effects dominate early-stage evolution with…
