How producers of public goods persist inmicrobial communities is amajor question in 8 evolutionary biology. Cooperation is evolutionarily unstable, since cheating strains can reproduce 9 quicker and take over. Spatial structure has been shown to be a robustmechanism for the 0 1 evolution of cooperation. Here we study how spatial assortmentmight emerge from native 1 1 dynamics and show that fluid flow shear promotes cooperative behavior. Social structures arise 2 1 naturally from our advection-diffusion-reactionmodel as self-reproducing Turing patterns. We 13 computationally study the effects of fluid advection on these patterns as amechanism to enable or 4 1 enhance social behavior. Our central finding is that flow shear enables and promotes social 5 1 behavior inmicrobes by increasing the group fragmentation rate and thereby limiting the spread of 6 1 cheating strains. Regions of the flow domain with higher shear admit high cooperativity and large 7 1 population density, whereas low shear regions are devoid of life due to opportunisticmutations.
