Learning Guide : Evidence for Evolution Bill Activity #10

To Think About: What evidence supports the “pattern” of evolution? In what ways do organisms share many conserved core processes and features?

1st Read About: Evidence of Evolution Pgs. 460-467 Campbell’s Biology, 9th edition (Title your notes in your BILL notebook. Also please use “2-sided column notes” or Cornell style format with the key points on the left and the notes on the right, feel free to leave space at the bottom of each page to write a summary, also add color and highlighting for the important ideas and key points. These are your notes you will be using for in class discussions and studying from.)  Direct Observations of Evolutionary Change. o Explain how research with soapberry bugs demonstrated observable evolutionary change. Sketch and label the graphs to support your explanation. o MRSA is in the news today because it is becoming increasingly common. Explain the evolution of MRSA’s resistance to methicillin.  Homology. o Define homology. How do homologous structures give evidence for evolution? o List and describe the anatomical homologies listed in the reading. o Describe what is meant by molecular homologies and why they go “beyond a shared code” o Describe what is summarized in an evolutionary tree. o Sketch and label a simple tree include hatch marks, several branch points and descendents of a common ancestor. What do the hatch marks represent? o Organisms that are distantly related can resemble each other. Explain convergent evolution and describe how analogous structures can arise. Give an example.  The Fossil Record o Explain how the fossil record documents the pattern of evolution. There are several ways. Include examples.  Biogeography. o Describe what is meant by biogeography. How is it affected by continental drift and the presence of endemic species?  Evolution as a Biological Theory. o If Darwin was alive today how would he respond to someone who says that evolution is “just a theory”?
