Are birds more closely related to mammals or reptiles?

How do we know? http://www.youtube.com/watch?v=j5KjCn7B6mU reptiles! Pose the question "How do we know?" to evaluate students' prior knowledge to the topic. How do we know?

Making Predictions On your dry erase boards, you are going to work with your group to make predictions about pictures I show you. Write a 2-3 sentence summary to explain the pictures. Use EVIDENCE in the pictures to form your response Think like a scientists!

Predict why these animals have such similar structures.

Predict why a whale would have a femur and pelvis but no hips.

Predict why these embryos look so similar and why the human and bird have gill slits

Predict why the chromosome for a human and a mouse look so similar

Summarize your conclusions from analyzing these pictures. 2-3 sentences

Evolution Defined…. Evolution is defined as change over time More specifically… Genetic change over time

Misconceptions Misconception 1: There is no evidence for evolution Why is this a misconception? Misconception 2: Evolution creates perfect organisms

What evidence do we have for evolution?

Where’s the Evidence? Fossils Homologous Structures Comparative Embryology DNA Vestigial Structures

Fossils Fossils show the existence of many different organisms through time that are related to existing organisms.

Homologous Structures Homologous structures show similarities in structures that suggests a common ancestor

Comparative Embryology The similarities in the early stages of development of vertebrates suggest these things could be distantly related

DNA We can collect quantitative data that proves relatedness between all living organisms today through similarities in DNA

Vestigial Structures Finding structures with no function in animals shows that their ancestors had a different body that needed that structure
