Antagonism correlates with metabolic similarity in diverse bacteria

In the Origin of Species, Charles R. Darwin [Darwin C (1859) On the Origin of Species] proposed that the struggle for existence must be most intense among closely related species by menas of their functinal similarity. It has been hypothesized that this similarity, which results in resource competition, is the driver of the evolution of antagonism among bacteria. Consequently  antagonism should mostly be prevalent among phylogenetically and metabolically similar species. We tested the hypothesis by screening for antagonismamong possible pairwise interactions between 67 bacterial species from 8 different environments. We found a clear association between antagonism and phylogeneticdistance, antagonism being most likely among closely related species. Read all our findings HERE
