Pleiotropy and the low cost of individual traits promote cooperation.
The evolution of cooperation is thought to be promoted by pleiotropy, whereby cooperative traits are coregulated with traits that are important for personal fitness. However, this hypothesis faces a key challenge: what happens if mutation targets a cooperative trait specifically rather than the pleiotropic regulator? Here, we explore this question with the bacterium Pseudomonas aeruginosa, whic...
متن کاملSynergistic Pleiotropy Overrides the Costs of Complexity in Viral Adaptation.
Adaptive evolution progresses as a series of steps toward a multidimensional phenotypic optimum, and organismal or environmental complexity determines the number of phenotypic dimensions, or traits, under selection. Populations evolving in complex environments may experience costs of complexity such that improvement in one or more traits is impeded by selection on others. We compared the fitnes...
متن کاملSynergistic Cooperation in the Food System
Meeting basic food needs involves using photosynthesis to harvest solar energy over extensive areas. This work-intensive process can consume the majority of human productive capacity leaving only small amounts of this capacity to provide other features to which most societies aspire. There are systems of technology which can make food production more efficient in terms of human productive input...

متن کاملSynergistic cooperation promotes multicellular performance and unicellular free-rider persistence
The evolution of multicellular life requires cooperation among cells, which can be undermined by intra-group selection for selfishness. Theory predicts that selection to avoid non-cooperators limits social interactions among non-relatives, yet previous evolution experiments suggest that intra-group conflict is an outcome, rather than a driver, of incipient multicellular life cycles. Here we rep...
