Thinking of the examples in your book of adaptive radiation,in which of the following environments might you be most likely to find adaptive radiation?

Question

Quizplus · Accepted Answer

Adaptive radiation occurs when a single species diversifies into multiple species, each of which fills a unique ecological niche. In this scenario, the fruit flies feeding on different yeast strains specific to different species of cacti in the desert would be most likely to undergo adaptive radiation as they are adapting to fill different niches within a specific environment. The other options - houseflies living in a garbage dump, earthworms feeding on detritus, and insects that are generalist feeders - do not provide as much opportunity for diversification and specialization.
