Quick summary: Students investigate the adaptations of the human hand and foot, and speculate about the role these played in human evolution. Students are asked to observe the structure and motion of their own hands and feet and report on their observations.
- Students understand the significance of the opposable thumb in humans and how this has influenced our evolution.
- Students recognise a range of adaptations of the human hand and foot.
- Students recognise how human feet and hands have evolved from the same homologous structure.
