  • Identifying Patterns in Observations

    Identifying Patterns in Observations

    Lessons

    This activity challenges students to identify observations that Darwin and Wallace made during their travels, as shown in the short film The Origin of Species: The Making of a Theory. Students then evaluate claims about evolution by natural selection based on these observations.

    Discovering the Wallace Line

    Lessons

    This activity supports the HHMI short film The Origin of Species: The Making of a Theory. Students are presented with a map of the Malay Archipelago and some field notebooks with observations of animals. By plotting which animals are found on which island, the students discover the Wallace Line—a sharp boundary that separates distinct Asian and Australian fauna.
