In evolutionary terms, what is mutualism?

Mutualism refers to a symbiotic relationship where both species involved derive benefits from the interaction. This can manifest in various ways, such as one species providing food or shelter for the other while receiving benefits in return, such as pollination in plants from insects. Such mutualistic relationships are significant in ecological systems because they enhance survival and reproductive success for both species, contributing to biodiversity and ecological stability. The positive feedback loop generated by mutualistic interactions illustrates a fundamental aspect of evolutionary dynamics, demonstrating how interconnectedness in ecosystems can lead to greater overall survival and adaptation.
