6. BELL WORK: Answer the following question in COMPLETE SENTENCES: What evidence do you think exists to support the theory of evolution?

7. Set up today’s notes… Page: 49 Date: 1-8-16 Title: Evidence of Evolution Essential question: What evidence supports the theory of evolution? No, NOT Cornell Notes!! You will take notes on your handout.

8. EVIDENCE Fossil Record Developmental Molecular Anatomical Homologies Biogeography Turn your journal sideways and copy the graphic organizer below. You will be writing notes UNDER each box:

9. BIOGEOGRAPHY: geographical distribution of living things In other words…where living things have been found around the world.

11. HOMOLOGIES: similarities among organisms Remember…homo = same Three types of homologies show evidence of evolution from a common ancestor:

12. ANATOMICAL: different species have similar structures but perform different functions

13. MOLECULAR: similarities in DNA sequences among different organisms *We find similarities in the DNA sequences of all organisms. *A closer match means a closer relationship!

14. DEVELOPMENTAL: different species develop from similar starting forms (embryos)

15. Fossil Record: all the discovered fossils and the information gained from them FOSSIL: the preserved remains of a prehistoric organism

16. Types of Fossils

17. Younger (newer) Older Lower = older “transitional fossils” show how species have changed over time incomplete – fossils were not left by every organism that ever lived two ways to determine age: Radioactive dating Relative dating

19. Things to Consider: Stasis: some organisms look the same from when they appear to when they disappear Sudden appearance: a species appears all at once and fully formed Sequential nature: organisms appear in a particular order What might cause stasis or sudden appearance? So what about the fossil record?

20. The picture to the right shows a series of major biological events that have taken place over the last 488 Million Years! Biologists were able to piece these events together based on evidence collected from fossils. Take notice of the extinctions. What happened immediately after each one?
