Question

The theory of divergent evolution adaptive radiation coevolution convergent evolution suggests that all the mammals alive today came from the same common ancestor.

Answer 1

This is definitely not convergent evolution (which would imply rather multiple ancestors) nor convolution, which does not involve ancestors, but describes an evolutionary process in which two or more species influence each other.

The correct answer is divergent evolution: it describes the process in which multiple species emerge from one ancestor species.
