Arch support
By this time, the feet of early humans had a modern-type arch.
Do you see the tooth marks on this ankle bone? Their shape and pattern are similar to those made by modern crocodiles. The back part of the heel bone is bitten off, too. A lake with crocodiles was located not far from where this early human lived. He or she may have been drinking from the lake at the wrong time.
