As you study two closely related predatory insect species, the two-spot and the three-spot avenger beetles, you notice that each species seeks prey before dawn in areas without the other species. However, where their ranges overlap, the two-spot avenger beetle hunts at night and the three-spot hunts in the morning. When you bring them into the laboratory and isolate the two different species, you discover that the offspring of both species are found to be nocturnal. You have discovered an example of:

Celeste Bowen · Answer 1

character displacement.

Explanation:

Character shift is a term used to explain the phenomenon in which differences between similar species whose distributions overlap geographically are accentuated in regions where species co-exist but are minimized or do not exist where species distributions do not overlap. In other words, character shifting occurs when one species acquires different characteristics due to competition with another. This can be observed in the example given in the above question.
