Answer
This statement is not supported because parallel evolution refers to species that evolve similarly but from a common ancestor. The diagram suggests species Q and R diverged from species P.
Step 2
B. species Q and R could be the result of convergent evolution.

Answer
This statement is also incorrect. Convergent evolution occurs when species from different evolutionary backgrounds develop similar traits. The diagram indicates a common ancestor.
Step 3
C. species P would appear in the fossil record later than species R.

Answer
This statement cannot be deduced from the diagram. The fossil record does not provide information on the exact order of species appearances related to the depiction.
Step 4
D. species Q and R could have arisen through a process of allopatric speciation.

Answer
This is the most plausible interpretation based on the diagram. Allopatric speciation occurs when populations become geographically isolated, leading to the emergence of new species.
