    However, the most familiar examples of increased access to resources through facilitation are the mutualistic transfers of nutrients between symbiotic organisms. A symbiosis is a prolonged, close association between organisms, and some examples of mutualistic symbioses include: Gut flora

  3. Cooperation (evolution) - Wikipedia

    en.wikipedia.org/wiki/Cooperation_(evolution)

    Symbiosis refers to two or more biological species that interact closely, often over a long period of time. Symbiosis includes three types of interactions—mutualism, commensalism, and parasitism—of which only mutualism can sometimes qualify as cooperation.

  8. Hologenome theory of evolution - Wikipedia

    en.wikipedia.org/wiki/Hologenome_theory_of_evolution

    Organisms in symbiotic relationships evolve to accommodate each other, and the symbiotic relationship increases the overall fitness of the participant species. Although the hologenome theory is still being debated, it has gained a significant degree of popularity within the scientific community as a way of explaining rapid adaptive changes that ...
