Answer

Brief Explanations:

Adaptive radiation occurs when there are new ecological opportunities. A catastrophic event causing mass - extinction clears niches for new species to evolve. An environment with few species and many resources provides room for a species to diversify. Newly - formed islands through volcanic activity offer unexploited habitats for colonization. Chromosome duplication via allopolyploidy can lead to new species and potential for radiation. Gene flow re - establishment between isolated populations does not typically trigger adaptive radiation as it reduces genetic differences rather than creating new opportunities for diversification.

Answer:

A. A catastrophic event leads to mass extinction. B. A species occurs in an environment with few other species and many resources. C. A species undergoes duplication of chromosomes via allopolyploidy. D. Islands form through volcanic activity and are subsequently colonized.
