The upper part of the human pelvis, the ilium, underwent two major structural changes during evolution that enabled humans to walk on two legs. One was the formation of cartilage and the second was the process of bone formation. New research identifies differences in the way bone cells are deposited on cartilage in the human ilium, compared to other primates and human long bones. The study, published in *Nature*, lays the genetic and evolutionary foundations for bipedalism, according to the authors.
