Description

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

In this Click & Learn, students explore a simplified evolutionary tree of chickens starting from the last common ancestor of birds and crocodiles, which lived about 250 million years ago. Students compare the bones of a chicken to those of its dinosaur relatives at key nodes of the tree, to pinpoint some of the similarities that suggest that birds are avian dinosaurs.

The accompanying “Worksheet” guides students’ exploration of the Click & Learn.

Student Learning Targets

  • Explain how shared anatomical features can provide evidence for evolutionary relationships.
  • Construct a simple evolutionary tree based on visual observations of anatomical similarities.
     

Estimated Time

One 50-minute class period to complete the Click & Learn and its associated worksheet.

Key Terms
