Big Ideas
  • Multiple independent lines of evidence—including fossils, biogeography, and homologies—support the theory of common ancestry for groups of organisms.
  • Scientific explanations for the unity and diversity of life are constructed through analysis and evaluation of historical and modern forms of evidence.
Essential Questions
  • How do fossils, biogeography, and homologies each provide evidence for common ancestry among groups of organisms?
  • What patterns can be observed in the fossil record that indicate relationships among different species?
  • How do scientists use homologies to infer evolutionary relationships?
  • Why is it important to use more than one type of evidence when studying common ancestry?
  • What are the strengths and limitations of each type of evidence in supporting scientific explanations about common ancestry?
