Adaptive radiation occurs when a) one species gives rise to multiple closely related species. b) several species adapt to one environment. c) species adapt to environments with high radiation levels. d) an individual adapts to varying environments.

Step 1
Adaptive radiation is an evolutionary process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches. Show more…

Which of the following is an example of adaptive radiation? (A) One population of squirrels becomes two separate species over a long time. (B) One population of lizards leads to 15 separate species over a short time. (C) One species of birds becomes better suited to its environment over time. (D) Two species of fish breed with each other.

Adaptive radiation is common following a period of mass extinction, probably because (a) the survivors of a mass extinction are remarkably well adapted to their environment (b) the unchang. ing environment following a mass extinction drives the evolutionary process (c) many adaptive zones are empty (d) many ecological niches are filled (e) the environment induces changes in the timing of development for many species
Adaptive radiation a. is the result of enriched uranium used in power plants. b. is the evolution of closely related species adapted to use different parts of the environment. c. results from genetic drift. d. is the outcome of stabilizing selection favoring the maintenance of adaptive traits.
