Russell Howard Tuttle (born August 18, 1939) is a distinguished primate morphologist, paleoanthropologist, and a four-field (linguistics, archaeology, sociocultural anthropology
and biological anthropology) trained Anthropologist.
He is currently an active Professor of Anthropology, Evolutionary Biology, History of Science and Medicine and the College at the University of Chicago.
Tuttle was enlisted by Mary Leakey to analyze the 3.4-million-year-old footprints she discovered in Laetoli, Tanzania.
He determined that the creatures that left these prints walked bipedally in a fashion almost identical to human beings.
