Performance expectationCommunicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
Emphasis is on a conceptual understanding of the role each line of evidence has relating to common ancestry and biological evolution. Examples of evidence could include similarities in DNA sequences, anatomical structures, and order of appearance of structures in embryological development.
Every item written to HS-LS4-1 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
