What year did apes walk on two legs?

Inconclusive, alas. There is good evidence that Australopithecus afarensis, an ape living between 4 and 3 million years ago, was if not exclusively, then still partly bipedal. Many primates are capable to some degree of bipedalism, if only for short periods, and there is some evidence that more advanced forms of bipedalism evolved among apes even before A. afarensis, but this data is far from conclusive. So all in all, approx. 4 million years ago is a reasonable estimate.
