Evolutionary biologists claim that the complex eyes in some molluscs (e.g., squids and octopuses) and vertebrates evolved independently. Which of the following observations, if made, would support this claim?
A) The lens structures of mollusc and vertebrate eyes are similar.
B) The light-sensing cells of both molluscs and vertebrates are structurally different.
C) The proteins that absorb light in both molluscs and vertebrates have almost identical amino acid sequences.
D) The bones to which the eyes of molluscs and vertebrates attach are different.

The structural difference in light-sensing cells between molluscs and vertebrates supports the idea of independent evolutionary paths for complex eyes in these groups, indicating convergent evolution rather than a shared ancestral trait.
