Yep, it's better explained on those cladograms :v:
The point is that I don't really see the "straight line" model working, evolution is more like a tree with multiple branches. In better words, A. Sediba is the closest thing to the Homo genus compared with other Australopithecus species we have at this moment, it may just be a close relative of the actual species that evolved into Homo, since in evolutionary biology there's no 100% sure "this species gave rise to this other one".

That's what an ancestor is though. You have ancestral fish because at [i]some point[/i] everything was a fish or other sea critter. A. Sediba, as it stands with the knowledge we have now, is our closest [i]Australopithecus[/i] ancestor. But there is always the possibility that we may find a closer one that's still part of the [i]Australopithecus[/i] genus. Science is subject to change.
