Answer 1

1) The correct answer is-

D- all of the above.

This is because both the organisms are from convergent evolution which shows how species have evolved separately but have similar (analogous) structures. Also they have homoplasy character shared but not present in their common ancestor.

2) The correct answer is-

D- Founder effect/genetic drift

This is because the founder effect is a case of genetic drift which is caused by a small population with limited numbers of individuals breaking away from a parent population.
