Final answer:
Australopithecus sediba could be the most recent ancestor of the genus Homo.
Step-by-step explanation:
The most recent ancestor of the genus Homo could be Australopithecus sediba. A. sediba is considered an important species as it appears in the fossil record around the time of the first emergence of the genus Homo. It is believed that A. sediba could be a descendant of Australopithecus africanus, which suggests that it may be a dead end within the lineage to humans.
