I will try a rhetorical device to show the vacuousness of this argument.

To the best of anyone's knowledge, every tetrapod that ever transitioned
from an arboreal to a terrestrial environment ultimately became a
quadruped. Why would the early proto-hominid have been any different?
In other words why aren't chimpanzees and gorillas bipedal?
