Abstract

This activity uses inquiry to investigate how large changes in shape can evolve from small changes in the timing of development. Students measure skull shape in fetal, infant, juvenile, and adult chimpanzees and compare them to adult skulls of Homo sapiens, Homo erectus, and Australopithecus afarensis. They conclude by re-interpreting their findings in light of Ardipithecus ramidus.
