Question

what is adaptive radiation? when individuals with the lowest fitness reproduce when many diverse species arise from a common ancestor when a species cannot find food

Explanation:

Adaptive radiation is a biological concept. It refers to the process where a single ancestral species diversifies into many different species, each adapted to different ecological niches. This occurs due to factors like availability of new habitats, resources, or environmental changes. The key idea is the rapid speciation from a common ancestor to fill various ecological roles.

Answer:

when many diverse species arise from a common ancestor
