Fair enough. I did mention it and was wrong on that.

But still, as far as I know and can find, the Sahelanthropus was at least primarily bipedal and still not human.

At any rate, it's baffling how we ended up heatedly discussing evolution and bipedalism due to dialogue in one of the less serious ecchi manga out there.
