Bipedality evolved in hominids more than 4 million years ago. Bipedals were a diverse group including the lineage of obligatory walkers that finally lead to humans. Important anatomical changes in this group were: enhanced lumbar lordosis, shortening of the ilium, and emphasize on the parasagittal movements. Long-distance running evolved much later and it was associated with well-developed plantar arches, strengthening of muscles supporting the erect trunk, and decoupling of the pectoral girdle and head. In addition to anatomical changes, humans have many physiological adaptations to long-distance running. It is likely that the ability to run long-distance has been important for the survival of our species.
