Finely layered grey and white tuff. Estimates are largely inferred from known relationships between metric data in living species, such as bone length or joint size and stature or body mass McHenry,; Grabowski et al. Clarendon Press. However, past analyses of the Laetoli tracks have also reached conflicting conclusions [ 69 — 17 ]. Taxonomic and biostratigraphic significance" Journal of African Earth Sciences. These experiments have provided a robust dataset that offers the basis for us to quantitatively understand in the present study the likely biomechanical causes of particular patterns of footprint shape variation. Some believed that the brain, not erect posture, led the way.
Laetoli Footprint Trails
Therefore, it is unlikely that the differences between the Laetoli and modern human footprints are influenced by differences in walking speed.
Laetoli at ~3.5 mya
In this paper, we report a novel set of hominin tracks discovered at Laetoli in the new Site S, comparing it to a reappraisal of the original evidence. Insights into the evolution of human bipedalism from experimental studies of humans and other primates. Masao et al. Limited to S1, mean values, standard deviation and range are provided.
