Description

Evidence for Evolution: Examining homologous, analogous, and vestigial anatomical structures. Students will learn about comparative anatomy and examine structures that are similar and different in both modern and ancient organisms. Students will compare similarities in pictures of embryos and will learn how these structures support the theory of evolution.

This unit on Evolution includes:

  • Informative slide show
  • Strategic notetaking guide
  • Two reading passages
  • Follow-up pages
  • A quiz
  • Answer keys

This unit is designed to address the following standards: 

NGSS MS-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. [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.]

NGSS MS-LS4-3. Analyze displays of data to identify linear and nonlinear relationships.

 to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy. [Clarification Statement: Emphasis is on inferring general patterns of relatedness among embryos of different organisms by comparing the macroscopic appearance of diagrams or pictures.] [Assessment Boundary: Assessment of comparisons is limited to gross appearance of anatomical structures in embryological development.]

Utah SEEd standard 7.5.3

Construct explanations that describe the patterns of body structure similarities and differences between modern organisms, and between ancient and modern organisms, to infer possible evolutionary relationships. (LS4.A)

Utah SEEd Standard 7.5.4

Analyze data to compare patterns in the embryological development across multiple species to identify similarities and differences not evident in the fully formed anatomy. (LS4.A)

I am so impressed with this unit which manages to be distance learning and hands-on at the same time.  Really well thought out and engaging activities that allow students to practice each of the eight Science and Engineering Practices.  Really no prep for me!

The elephant article was excellent but I also thought the lab on dissecting a flower was broken down so easily, even telling me where to get inexpensive flowers!  This resource helped me teach this challenging standard in an engaging way.  Worth every penny!

My students loved this unit. I was able to present different elements of it throughout the month. It is hard to find interesting non-fictional, age-appropriate text for my students that they will enjoy. This was a great unit that aligned well for my students who have very different goals within the same group.
