MS-LS4-2: Anatomical Evidence of Evolutionary Relationships

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. (Patterns)

Clarification Statement: Emphasis is on explanations of the evolutionary relationships among organisms in terms of similarity or differences of the gross appearance of anatomical structures.

Assessment Boundary: none


The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour.  These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection. Learn more about assessment design here.




Anatomical structures
 - Similarities
 - Differences
Modern organisms  (e.g. skulls of modern crocodiles, skeletons of birds)
Fossil organisms (e.g. skulls of fossilized crocodiles, fossilized dinosaurs)
Evolutionary relationship
