ANSWER:Step 1 of 3
Adaptive radiation is a biological phenomenon when a single ancestral species gives rise to multiple diverse species; each adapted to occupy different ecological niches. It is a process of rapid diversification that happens when a population or group of organisms encounters new and diverse environments with different selection pressures.
