Question

Quizplus · Accepted Answer

Convergent evolution refers to the development of similar traits in unrelated organisms in response to similar environmental pressures. The best example of this is the development of a cartilage skeleton in sharks and a bone skeleton in dolphins, as both share similar aquatic environments and have evolved adaptations to thrive in those environments. The other choices may show some similarities, but not to the extent of convergent evolution.
