5 minute talk 1

Main Learning Objectives: Compare and contrast the evolutionary adaptations of two species Propose your hypothesis on how it happened to the class

Select two species in the same biological class

1) Select one trait homologous structures/ genes or enzyme.

a. compare and contrast the structure or function of this feature in each species.

b. select one structure or enzyme that is vestigial remnant from an earlier common ancestor in one or both organisms.

2) Explain how the evolution of trait a is beneficial to both species in their particular environment or how trait b. may pose problems for one or both organisims

3) How or why do you propose the organisms inherited their particular version of the structure

4) Select one structure or enzyme that is vestigial remnant from an earlier common ancestor in one or both organisms.

You may use PowerPoint or printed images to visualize the adaptation.

Include the order, family, genus and species of both organisimon your first page/slide

No more than three PowerPoint slides or 3 printed images.
