Researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, along with an international team of collaborators, have recently discovered multiple assemblages of Homo
erectus footprints in northern Kenya that provide unique opportunities to understand locomotor patterns and group structure through a form of data that directly records these dynamic behaviours.
Using novel analytical techniques, they have demonstrated that these H.
erectus footprints preserve evidence of a modern human style of walking and a group structure that is consistent with human - like social behaviours.
Not exact matches
Based on experimentally derived estimates of body mass from the Ileret hominin tracks, the researchers have also inferred the sexes of the multiple individuals who walked across
footprint surfaces and, for the two most expansive excavated surfaces, developed hypotheses regarding the structure of these H.
erectus groups.
«Homo
erectus walked as we do: 1.5 - million - year - old
footprints provide window to the life of Homo
erectus.»
The size of the Ileret
footprints is consistent with stature and body mass estimates for Homo ergaster /
erectus, and these prints are also morphologically distinct from the 3.75 - million - year - old
footprints at Laetoli, Tanzania.
But the shoulder and pelvis of H.
erectus were still primitive, says Jungers, so the
footprints also show that on the path to modernity, «the foot led the way.»
The stature of S1 falls within the range of modern Homo sapiens maximum values; it also fits the available Homo
erectus sensu lato estimates based on fossil remains (Ruff and Walker, 1993) and on
footprints (Bennett et al., 2009)(Figure 12).
We learn in the February 27 issue of Science that a team working at Illeret, near Lake Turkana in Kenya, or many years the site of fossil finds, has uncovered two trails with
footprints estimated to be 1.5 million years old and likely made by individuals assigned to Homo ergaster /
erectus.
