Which of the following is part of a clade believed to have died out, leaving no descendants?

Paranthropus robustus

Australopithecus africanus

Homo erectus

Homo sapiens sapiens

Paranthropus robustus

Explanation:

2.5 million years ago some autralopithecines were identified by dating fossils from South Africa, meaning they lived a good period of time. Of these, Australopithecus africanus is well known and is a little closer to our species. Other fossils found in excavations in both southern Africa and eastern Africa have been found to be of more recent specimens 2.5 to 2 million years ago. These specimens were classified as Paranthropus robustus and Paranthropus boisei. These australopithecine species became extinct and left no current descendants.
