Modern humans, homo sapiens, have been around for a few hundred thousand years. We have good remains and artifacts dating back 200 000 years.
We also have some very good remains of Homo Erectus/Ergaster from around 1.5 million years ago who were sufficiently different to be called a different species, but who passed their genes down to us.
With those genes we also inheritted our modern gait. yep, that's right, analysis of fossilized footprints found in kenya along an ancient riverbed shows that ergaster, although his legs were slightly shorter and arms longer, had a similar gait and foot structure to ours.
