Considering the answers; A. are still sibling species B. shared a common ancestor more recently with each other than either did with the other two species C.May merge into a single species if their hybrids remain fertile over the course of many generations. D. A and B only E. A, B, and C The answer will be E. If no other species can hybridize, then species W and Y are still sibling species, shared a common ancestor more recently with each other than either did with the other two species and also may merge into a single species if their hybrids remain fertile over the course of many generations.
