Which pair of organisms show convergent evolution?
a) despite being close relatives, cattle and giraffes have drastically different neck lengths.
b) ducks develop different mating dances to avoid mating with other ducks from different species.
c) a bluegill sunfish and a redear sunfish, closely related, have similar fin shapes and color patterns.
d) tasmanian devils and wolverines are both thick-bodied predators with crushing teeth and similar food sources, but they are not at all related.

The correct answer is D)  

Convergent evolution is the evolution of unrelated species ( those having different ancestors) that creates similar forms and functions. It results in the development of analogous structures.

In this case, Tasmanian devils and wolverines both have similar morphological forms ( like thick bodied predators, crushing teeth) but they are not related that is they have different ancestors.

Thus, Tasmanian devils and wolverines show convergent evolution.

looks like the answer is     c     to me!
