Laser scanning was used to plot the exact dimensions of the prints
The earliest footprints showing evidence of modern human foot anatomy and gait have been unearthed in Kenya.
The 1.5-million-year-old footprints display signs of a pronounced arch and short, aligned toes, in contrast to older footprints.
The size and spacing of the Kenyan markings - attributed to Homo erectus
- reflect the height, weight, and walking style of modern humans.
The findings have been published in the journal Science
The footprints are not the oldest belonging to a member of the human lineage. That title belongs to the 3.7 million-year-old Australopithecus afarensis
prints found in Laetoli, Tanzania, in 1978.
