Humanlike footprints, supposedly 150 – 600-million years old, have been found in rock formations in Utah,a Kentucky,b Missouri,c and possibly Pennsylvania.d At Laetoli, in the east African country of Tanzania, a team headed by Mary Leakey found a sequence of humanlike footprints.e They were dated at 3.7-million years. If human feet made any of these prints, then evolutionary chronology is drastically wrong.
