Professor Tuttle has conducted pioneering functional morphological work on apes via electromyography (EMG) and meticulous dissections, leading to the conclusion (recently supported by fossils) that chimpanzees poorly represent the locomotive pattern that underpinned the evolution of human terrestrial bipedalism. He also provided a functional interpretation of the 3.66 million-year-old hominid footprint trails at Laetoli, Tanzania, which has held up well vis-à-vis challenges of other commentators.
