Paranthropus
For the most part the Australopithecus species A. afarensis, A. africanus, and A. anamensis either disappeared from the fossil record before the appearance of early humans or seem to have been the ancestors of Homo habilis. P. boisei and P. aethiopicus, on the other hand, continued to evolve along a separate path distinct and unrelated to early humans. Paranthropus shared the earth with some early examples of the Homo genus, such as H. habilis, H. ergaster, and possibly even H. erectus.
