In Laetoli Footprints Preserve Earliest Direct Evidence of Human-Like Bipedal Biomechanics by Raichlen et al., human volunteers walking either upright or crouched left footprints in the sand. These prints were then analyzed and compared to the footprints left by Lateoli hominins 3.6 million years ago. The results suggest that our ancestors, even that far in the past, had an upright posture and a gait somewhat similar to ours. The study was reported at Washington Post, Scientific American blog, BusinessWeek, Laelaps, Wired Science, Softpedia, ThisDay, Arizona Daily Wildcat, and Ecographica, among others.
