Question: 453

3. Convergent evolution can result in all of the following EXCEPT

A. structures that have similar functions
B. behaviors that are similar
C. different species that resemble one another
D. production of a single species from two originally different species
E. niches that are similar

Correct Answer: D

Explanation:

D Convergent evolution is the evolution of two totally separate species along similar lines, so that they both produce features that have similar functions. It can result in everything described, but it cannot make the two different species into a single species. Remember, the species were originally very different, and their underlying structures are still different. They just share some common behaviors and features. (Remember also that this is a LEAST/EXCEPT/NOT question-you're looking for the "wrong" answer.)
