Laetoli footprints

Description

These footprints were made about 3.6 million years ago by a bipedal hominid, likely Australopithecus afarensis. They are the earliest direct evidence of homonid bipedalism, though it is likely Ardipithicus was walking upright two million years earlier. Disclaimer: This file is not made directly from scan data. I used available topographic imagery to create a rough approximation, and cleaned up the result to make an idealized artistic representation of the footprints. There is no scientific value to the file, and it is not a replica but an interpretation and close approximation to the original.
