Students often struggle with the concept of homologous and analogous structures, especially in on-level Biology classes. This activity is designed to provide both virtual and hands-on options for teachers based on the needs and strengths of their students. Students will compare and contrast the morphology of vertebrate forelimbs, and will use this knowledge to draw conclusions about their common ancestor and descent with modification. Students will also consider adaptation and how structure is shaped by selection pressures to suit the necessary function of limbs.
