Does Adaptive Radiation increase biodiversity after a mass extinction?

The given statement is true. Adaptive radiation is a process in which a single ancestral species rapidly diversifies into many descendant species, each occupying a unique ecological niche. Adaptive radiation can increase biodiversity after a mass extinction by filling ecological niches left vacant by extinct species. This process allows surviving species to rapidly evolve and diversify, creating new forms of life and increasing biodiversity. Therefore, the statement is true.

Adaptive radiation is a well-documented process that has been observed in many different groups of organisms, including birds, mammals, fish, and plants. It has played a significant role in shaping the diversity of life on Earth, particularly after mass extinctions.
