Earliest 'human footprints' found

Nairobi, 27 Feb-(ANA)-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.

Those prints, however, showed comparatively flat feet and a significantly higher angle between the big toe and the other toes, representative of a foot still adapted to grasping. (ANA)
