According to this article,

Quote:
The traditional view is of bipedalism evolving gradually from the four-legged "knuckle-walking" displayed by chimpanzees and gorillas today.

Now, a study published in the journal Science disputes this idea.

The British authors of the study say that upright walking was always a feature of great ape behaviour.

Humans inherited it without ever passing through a knuckle-walking phase.

They believe that knuckle-walking evolved only recently as a way of getting around the forest floor.

Uh-huh. So we now know more than we used to. Is this a problem?
