Hatala compared measures of the depth and shape of Laetoli prints with similar measures of footprints made in moist soil by men from a Tanzanian community of herders and farmers who rarely wear shoes. While walking, ancient Laetoli individuals flexed their big toes more when pushing off and extended their hips less than the African men did, Hatala said.
CALGARY, Alberta — Hominids that left footprints in volcanic ash at Laetoli, Tanzania 3.6 million years ago walked differently than people today do, Kevin Hatala, an anthropologist George Washington University in Washington, D.C., reported on April 11 at the American Association of Physical Anthropologists annual meeting. His conclusion challenges a recent study suggesting that Laetoli folk took humanlike strides (SN Online: 3/22/10).
