Disciplinary Core Ideas: LS4.A Anatomical similarities and differences between various organisms living today and between them and organisms in the fossil record, enable the reconstruction of evolutionary history and the inference of lines of evolutionary descent.
Notes: NGSS includes the idea that anatomical similarities and differences can be used to infer lines of evolutionary descent and, by extension, degree of relatedness, but it does not say explicitly that the greater the degree of similarity the more closely organisms are related.
