I sent you something earlier about the ancient form of African ape that was announced today called "Ardi." This sounds something like an orang pendek, though a bit larger.
This is Ardi's foot:
Compare it with the orang pendek track:
Ardi's anatomy suggests that the original African apes from which we, chimps, bonobos and gorillas descend were bipedal but still had the grasping toe. Ardi was the size of a chimp, which is consistent with the description of the orang pendek that the CFZ team saw.
Perhaps the orang pendek represents a relic primitive ape species.

The original apes were briachators. Gibbons and siamangs have held onto the brachiating and can walk bipedally. It is likely that Ardi evolved from a brachiating species.

It has recently been discovered that man did not evolve from a knuckle walking species. Knuckle walking most likely evolved from brachiating ancestors, and it evolved twice, once in gorillas and once chimps and bonobos.
