Dogs (Canis lupus familiaris)and gray wolves (Canis lupus)can interbreed to produce viable, fertile offspring. These species shared a common ancestor recently (in geologic time)and have a high degree of genetic similarity, although their anatomies vary widely. Judging from this evidence, which two species concepts are most likely to place dogs and wolves together into a single species?
A) ecological and morphological B) ecological and phylogenetic C) morphological and phylogenetic D) biological and morphological E) biological and phylogenetic
