People have often wondered how humans came to take over the earth. Some theorized that humans descended from primates that learned to walk. Many scientists have studied the items left behind trying to figure this out. That’s why finding human footprints from 350 thousand years ago is exciting. It gives another piece to the puzzle of the mystery of humans. While not the oldest hominid footprint, scientists still liked finding these footprints. They showed a group of people that walked upright just like us.
