WHO , walked on this path ?

This article is about scientists finding footprints for 30 years ago. The discovery comes from a trackway site in Laetoli, Tanzania. Researchers discovered footprint trails from a few human ancestors who had walked across a wet field. The footprints shows that the hominids made a deep heel and toe imprints when they walked across a soft surface. That pattern is a cardinal sign of a humanlike gait. Gait is is the pattern of movement of the limbs of animals, including humans. Previous calculations of Laetoli footprint depths were similar to the even heel and toe depths left by people walking in their usual fashion. They still dont know where these footprints came from. I believe that these footprints did come from humans. The way the footprints are described seems that it hadf to have been a early human creature. Hopefully they will find out what really made the footprints.
