Which of the following is true of the complex eye?
A) It is an example of convergent evolution because of the borrowed crystallin genes that evolved independently.
B) It is an example of common ancestry because the development of all complex eyes in bilaterians is controlled by the same gene, Pax-6.
C) It is an example of deep homology because its growth and development in different lineages result from underlying genetic mechanisms that are inherited from a common ancestor.
D) a and b
E) a, b, and c

Question

Quizplus · Accepted Answer

The complex eye exemplifies convergent evolution due to independently evolved crystallin genes, common ancestry through the Pax-6 gene controlling eye development across bilaterians, and deep homology because its development across different lineages is governed by genetic mechanisms inherited from a common ancestor.
