The oldest footprints of a modern foot 
man's ancestors began to walk with one foot anatomically modern about 1.5 million years ago. This is demonstrated by a group of footprints left by individuals
Homo ergaster , the first of the hominin has the same body proportions of Homo sapiens
. The discovery was made by researchers at Rutgers State University of New Jersey and Bournemouth University, Britain, published in the journal "Science
. The footprints were discovered in two sedimentary layers dating back, in fact, 1.5 million years ago near the town of Ileret in northern Kenya and bear traces of the form and structure of soft tissues, data that can be derived from fossilized remains of bones. The upper sedimentary layer contained three sets of tracks: two of two tracks each, and one of seven tracks, plus some other scattered impressions. A second sedimentary layer, five feet deep, kept two sets of footprints footprint more isolated, probably due to a boy. In these samples, the big toe is parallel to the other toes, Furthermore, the print shows a very pronounced arch support, similar to that of modern man, and short fingers, suitable for an upright biped with normal gait. Size, spacing and depth of footprints led to speculate gait, weight and height of the subject, all results comparable with those of modern man. The footprints of the adult show in particular a person's height of 1.75 meters. Several other hominid fossil footprints have been discovered in recent decades, the most famous of which are those found in 1978 by Mary Leakey at Laetoli, in Tanzania, which date back 3.6 million years ago well. These were attributed to a possible oldest ancestor of man,
Australopithecus afarensis , showed an upright posture and bipedal gait, but the arch was much less pronounced and the big toes diverged.
