D)the amniotic egg of crocodiles and mammals

Quizplus · Accepted Answer

Wings in birds and bats are an example of convergent evolution because they evolved independently in these two groups in order to fulfill a similar function of flying. The other choices are not examples of convergent evolution as they either evolved from a common ancestor (lungs in lungfish and turtles) or have a shared evolutionary history (jaws in sharks and lizards, the amniotic egg of crocodiles and mammals).
