However, there has been much debate over when and how a human - like bipedal gait first emerged in the hominin clade, largely because of disagreements over how to indirectly infer biomechanics from skeletal morphologies.

Sure, positive selection is the cool kid on the block, but I think it would be very instructive, and perhaps even more convincing to also introduce purifying selection (because, hey, there are a lot of sequence / functions / features conserved across any chosen clade), and the awesomeness that is neutral evolution (because otherwise we're training students to look for zebras see function everywhere they look).
