アウストラロピテクス・アファレンシス
Dr. Grine is a major proponent in the argument that species of robust australopithecine should be given their own genus name, "Paranthropus". He also argues that the genus "Australopithecus" is paraphyletic which would require a new taxonomic designation for specimens included under "Australopithecus afarensis" to "Praeanthropus africanus".
