Beginning in the late Miocene and into the early Pliocene, upright walking tendencies began to develop among the hominin tribe. Upright walking tendencies slowly transformed into obligate bipedalism during the pliocene within the hominin lineage. This shift in locomotor strategy is notably marked by the gradual change in arm to leg ratio that we see when comparing early and later hominins. Early hominins have short legs and very long arms while later hominins have longer legs and short arms.
WHAT YOU ARE DOING.
Your task for this activity will be to compare and contrast the locomotor strategies of the following three hominin species: Ardipithecus ramidus, Australopithecus afarensis and Homo erectus. You will accomplish this by answering the questions below
