A symbiotic relationship between two species where both organisms benefit from the interaction. These partnerships often involve exchanges of resources, services, or protection that enhance survival or reproduction for both partners.
From Latin 'mutuus' meaning 'reciprocal' or 'mutual,' with the suffix '-ism.' The biological concept was formalized in the 19th century as naturalists recognized cooperative relationships alongside competitive ones in nature.
Mutualism proves that cooperation can be just as important as competition in evolution! Flowering plants and their pollinators have co-evolved for millions of years in an ancient partnership—flowers get reproduction services while pollinators get nectar meals.
