Knowledge
Students know:
- The more closely related the organisms, the longer the embryonic development proceeds in a parallel fashion (e.g., mammals and fish are more closely related than they appear based on adult features (presence of gill slits), human embryos have tails like other mammals but these features disappear before birth, etc.).
Skills
Students are able to:
- Obtain pictorial data of embryological development across multiple species from published, grade-level appropriate material from multiple sources.
- Organize the displays of pictorial data of embryos by developmental stage and by organism to allow for the identification, analysis, and interpretation of relationships in the data.
- Analyze the organized pictorial displays to identify linear and nonlinear relationships.
- Use patterns of similarities and changes in embryo development to describe evidence for relatedness among apparently diverse species, including similarities that are not evident in the fully formed anatomy.
Understanding
Students understand that:
- Comparison of the embryological development of different species reveals similarities that show relationships not evident in the fully formed anatomy.
