    "abstract": "We demonstrate diversification rather than optimisation for highly\ninteracting organisms in a well mixed biological system by means of a simple\nmodel and reference to experiment, and find the cause to be the complex network\nof interactions formed, allowing species less well adapted to an environment to\nflourish by co-interaction over the `best\u0027 species. This diversification can be\nconsidered as the construction of many co-evolutionary niches by the network of\ninteractions between species. Evidence for this comes from work with the\nbacteria Escherichia coli, which may coexist with their own mutants under\ncertain conditions. Diversification only occurs above a certain threshold\ninteraction strength, below which competitive exclusion occurs.",
