Without exception, living non human primates habitually move around on all fours, or quadrupedally, when they are on the ground. Scientists generally assume therefore that the last common ancestor of humans and chimpanzees (our closet living relative) was also a quadruped. Excactly when the last common ancestor lived is unknown, but clear indications of bipedalism, the trait that distinguishes ancient humans from other apes, are evident in the odlest known species Australopithecus, which lived in Africa roughly four million years ago.
Bipedal apes are more evolutionary advantaged than quadrupedal ones.
