What is the Result of Adaptive Radiation

Question

What is the result of adaptive radiation?
A) the extinction of one species and the replacement with another
B) the diversification of one or a few species into a varied group of descendants
C) symbiosis between eukaryotes and prokaryotes
D) convergent evolution in which unrelated species take similar forms

Accepted Answer

Adaptive radiation is the process by which a single species or small group of species evolve over a relatively short time period into a wide array of descendants that differ in traits and ecological roles. This process leads to the diversification of a few species into a varied group of descendants. It does not necessarily result in the extinction of one species and its replacement with another, nor does it always involve symbiosis or convergent evolution.
