What is "co-adaptation"

alt. A mutual adaptation of species, organs or genes. n. A mutual adaptation of species, organs or genes.

In biology, co-adaptation, or coadaptation refers to the mutual adaptation of:

• Species: see mutualism, symbiosis. For example, take note of the relationship that exists between the ant Pseudomymrex ferruginea and the plant Acacia hindsii. This is generally termed coevolution.
• Traits, often at different levels of biological organization. For example, ecophysiology and evolutionary physiology have focused on the coadaptation of behavior with physiology.
• Organs: see the evolution of the eye.
• Genes or gene complexes: see Linkage disequilibrium, epistasis

These are types of evolutionary adaptations because they involve cross-generational changes in the genetic compositions of populations in response to natural selection for the mutual benefit of both parties as they develop and corroborate their mutually beneficial relationship.
