Question

Between 3 and 2 mya, the ancestors of Homo became reproductively isolated from the later austrlopithecines, such as A. robustus and A boisei, the latter of which coexisted with Homo until around _____ mya

Answer 1

Australopithecus robustus and Australopithecus boisei, part of the robust australopithecines, coexisted with early Homo species until about 1 million years ago.

Step-by-step explanation:

The robust australopithecines, including Paranthropus robustus and Paranthropus boisei, coexisted with the early Homo species until about 1 mya (million years ago). The later australopithecines became reproductively isolated from the ancestors of Homo between 3 and 2 mya, during which time several australopithecine species roamed the African continent. It is known that the descendants of the genus Homo, such as Homo erectus and Homo habilis, continued to evolve and eventually gave rise to modern humans.
