Adaptive radiation occurs within a single lineage
Explanation:
Adaptive radiation generally occurs when an organism enters a new area and different traits affect its survival. An adaptive radiation is a burst of evolution, creating several new species out of a single parent species, which simply means that adaptive radiation occurs when a single lineage produces many descendant species. Adaptive radiation is considered to be a rapid process, where adaptation from a recent common ancestor takes place in a short period of time (with respect to geological time, of course).
