adaptive radiation

What is adaptive radiation?

Adaptive radiation refers to the rapid diversification of a group of organisms into various species, each occupying a different ecological niche.

It occurs when a common ancestor gives rise to multiple lineages, and each lineage evolves specific adaptations to exploit different resources or habitats. This process often occurs in response to environmental changes, such as the colonization of new habitats or the disappearance of competitors.

Adaptive radiation can lead to the evolution of diverse body forms, behaviors, and physiological characteristics within a relatively short period of time.
