bipedalism

You could get the independent evolution of bipedalism multiple times.

Instead, they’re up in the trees, moving with hand-assisted bipedalism, much like an orangutan, gibbon, and siamang do now.

In that case, bipedalism wouldn’t be a new locomotion, it’d be an old locomotion.

Darwin hypothesized that bipedalism and tool use and canine reduction and brain size evolve in concert.

In fact, bipedalism could have evolved independently in different hominins in Africa.
