- A new study suggests that the arch that crosses the width of each of our feet could be one of the reasons why humans have evolved to stand and walk upright on two legs.
- These arches help to harden the feet enough to be able to resist the forces on the feet caused by walking, running or even jumping.
- The new study suggests that it could even be a big step forward as to why our ancestors could slowly learn to walk upright with only two feet.
