Interactions among microbial cells can generate new mozelle riesling chemistries and functions, but exploitation requires establishment of communities that reliably recapitulate community-level phenotypes.Using mechanistic mathematical models, we show how simple manipulations to population structure can exogenously impose Darwinian-like properties on communities.Such scaffolding causes communities to participate directly in the process of evolution by natural selection and drives the evolution of cell-level interactions to the point where, despite underlying stochasticity, derived communities give rise to offspring communities that faithfully re-establish parental phenotype.

The mechanism is akin to a developmental process (developmental correction) that arises from density-dependent interactions among cells.Knowledge of ecological factors affecting evolution of developmental correction has implications for fume mini flavors understanding the evolutionary origin of major egalitarian transitions, symbioses, and for top-down engineering of microbial communities.
