How can we use embryology as one piece of multiple lines of evidence to support the claim that very diverse-looking species are evolutionarily related?
Cycle Summary
Session
11
Elicit
Students participate in a class discussion on how an organism’s features can or cannot indicate a relationship with another organism.
Engage
Students look at different organisms and predict whether or not they are related.
Explore
Students complete an online Guess the Embryo Activity with analysis questions or work in groups to compare embryonic development.
Session
12
Explain
Students read an article on comparative embryology and answer the analysis questions.
Session
13
Elaborate
Students complete the PBS Evolution Activity: All in the Family with analysis questions.
Evaluate
Students complete a summative assessment over the concept.
Extend
Extend
Students investigate how DNA is used to further understand evolutionary relationships.
In this cycle, students consider the study of embryology as a final piece of evidence to support the claim that diverse looking species are related. Students use online games and readings in order to explore how embryology has been used to support the theory of evolution.
