The biology class agenda discusses form and function in organisms. The teacher will define evolution, form, function, comparative anatomy, homologous structures, analogous structures, and vestigial structures. Students will learn about the relationship between an organism's form and its function, and how comparative anatomy is used to study this relationship across different species. The teacher will also explain how homologous structures have similar forms but different functions, while analogous structures have similar functions but different forms.

2. Today’s Agenda: Thurs. Dec. 1, 2011 Warm-Up: Finish up Summarizations (Due Today) Lesson: Form and Function Lecture

3. Today’s Objectives: I will define: evolution, form, function, comparative anatomy, homologous structure, analogous structure, and vestigial structure. I will recognize the relationship between form and function in living things.

4. What is Evolution? Evolution is the process by which species change over time.

5. Form vs. Function Form is the visual appearance and configuration of an organism. Function is any type of life process carried out by an organism.

6. Comparative Anatomy Comparative Anatomy is a method by which scientist study the physical features and body parts of different animals to discover how they are related or similar.

7. Homologous Structures Homologous Structures are structures that have similar form but different functions. These structures look alike in some ways, but they do different things.

9. Analogous Structures Analogous Structures are structures that have similar function but different forms. These structures do the same thing, but they look different.

11. Vestigial Structures Vestigial Structures are structures that don’t play a role in the way an organism functions. They are body parts that don’t really do much work in the body.
