Remember when the gracilis and robustus species of Australopithecus became female and male of a single species? And then later gracilis was said to have given rise to both robustus and afarensis? It seems like they change that mess of an evolutionary tree every time they find a new fossil. I think hilarious that they expect us to accept this stuff as fact when they can't even agree among themselves.

The operation is thus: We know that the general idea is correct though any or all of the specifics are subject to change.
