The emergence of many diverse species from a common ancestor is called
A) adaptive radiation.
B) gradualism.
C) allopatric speciation.
D) hybridization.

Question

Quizplus · Accepted Answer

Adaptive radiation is the process by which a single species evolves into many diverse species, often as a result of different populations being isolated from one another and adapting to their unique environments. This leads to the development of a variety of new traits and adaptations, resulting in the formation of multiple new species over time. Gradualism refers to the gradual accumulation of small changes over time that lead to speciation, whereas allopatric speciation occurs when populations become geographically isolated from one another and evolve independently. Hybridization involves the interbreeding of two different species to create a hybrid offspring, but does not necessarily result in the emergence of many new species.
