Homo erectus was the first to have the long legs and shorter arms that would have made it possible to walk, run and move about Earth's landscapes as we do today.

Who was the first to walk upright?

Homo erectus, or the first humans to walk upright, lived longer than we previously thought, according to new research.

When was walking upright invented?

From at least 6 to 3 million years ago, early humans combined apelike and humanlike ways of moving around. Fossil bones like the ones you see here record a gradual transition from climbing trees to walking upright on a regular basis. Sahelanthropus may have walked on two legs.
