You are starting a Ph. D. program in evolutionary biology, and you want to observe evolution in action. To plan your dissertation on adaptive radiation, you need to find a study site. In what type of environment is adaptive radiation most likely to occur?

In the environment with empty ecological niches available.

Explanation:

Adaptive radiation is most likely to occur in the environment where ample resources are available to support the survival of new species. These empty ecological niches allow diversification of ancestral species leading to adaptive radiation. Resource availability also ensures least or no competition.
