Some 7% modern humans retain ape-like fexible feet

A very curious story this one: a study performed on 398 visitors of Boston Museum of Science revealed that one of every thirteen people retain flexible characteristics in their feet, reminiscent of our ape cousins.

Most of us have very rigid feet, helpful for stability, with stiff ligaments holding the bones in the foot together. 

When primates lift their heels off the ground, however, they have a floppy foot with nothing holding their bones together. 

This is known as a midtarsal break and is similar to what the Boston team identified in some of their participants.
