Guiding Question: How do scientists use evidence (anatomical and embryological) to determine evolutionary relationships?
LS4-2: Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.
Students should be able to…
- State a CLAIM that relates similarities and differences in organisms and their evolutionary relationships
- Identify & describe multiple pieces of EVIDENCE, including similarities & differences in anatomical patterns of living and fossilized organisms.
- Use REASONING to connect evidence and explain that organisms that share a pattern of anatomical features are likely to be more closely related, and that changes over time in the anatomical features observable in the fossil record can be used to infer lines of evolutionary descent
LS4-3: Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.
Students should be able to …
- ORGANIZE displays of pictorial data of embryos by developmental stage and by organism.
- Analyze pictorial displays to identify relationships, including patterns of similarities in embryos across species and as embryos develop.
- INTERPRET data by using patterns of embryo development to describe evidence for relatedness.
Task 2: Evidence of Change over Time
- Explore stations of anatomical and embryological evidence
- Class review of stations
- Notes: Comparative Anatomy
Student understanding will be measured by:
- Formative Assessment: Task 2 Exit Slip
- Summative Assessment: Evolution Quiz
