Quizplus · Accepted Answer

The observation that offspring of male tree frogs with long calls spend more time feeding and grow faster than offspring of male tree frogs with short calls supports the good genes hypothesis. This hypothesis suggests that certain traits in males (such as a long call in tree frogs) evolve because they indicate genetic quality that is beneficial to the offspring. In this case, the offspring of males with long calls are healthier and grow faster, indicating that these males possess good genes that are beneficial for their offspring.
