  • New Laetoli Footprints and Hominin Body Size

    New Laetoli Footprints and Hominin Body Size

    Data Points

    Scientists were excavating a site in Laetoli, Tanzania when they uncovered two new sets of hominin tracks located about 150 meters south of the tracks found by Mary Leakey in the 1970’s. They estimated the heights of the two individuals using the size and shape of the footprints.
