Lesson 2: ANATOMICAL FEATURES
Duration of Days: 3
Lesson Objective
LP 1.2
- I can construct and justify a claim abut the relationship between two (2) species based on patterns in anatomical features.
Why/ How is there 8.7 million species here on Earth?
How do we know what species came before now and what happened to them?
What is the origin of life? How do we know?
What is a species? What factors lead to the creation of a species?
How/ why do species go extinct?
Homologous Structure
Analogous Structure
HS-LS4-1
Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
HS-LS4-5
Evaluate the evidence supporting claims that changes in environmental conditions may result in:
- Increase in number of individuals of some species
- Emergence of new species over time
- Extinction of other species
A connection to SAT skills can be made through critical analysis and comparison of scientific evidence, which aligns with the skills assessed in the SAT Reading and Writing sections. Understanding how genetic information, fossil records, and anatomical evidence contribute to the theory of evolution requires students to evaluate and compare various types of data, make inferences, and identify key relationships. These tasks are similar to those required in the SAT, where students must analyze passages, compare differing viewpoints, and draw conclusions based on evidence. The process of interpreting genetic evidence and adaptation patterns also involves logical reasoning, a skill central to SAT problem-solving.
Student will be looking at the anatomy of various species in order to see evolution trends. Students will look at how this anatomical changes help to serve a function for that species (example - dolphin has flippers to swim where a monkey has fingers to climb and grab)
