Evidence for Evolution Station Lab Station 1: Fossil Notes Define the two types of fossils: a. Body fossils:___________________________________________________ b. Trace fossils:___________________________________________________ The shape of animals teeth is determined by what factor?_______________________ Station 1 Questions 1. Do you think the pattern of change shown by the horse teeth supports this hypothesis? Why or why not? 2. How would you test this hypothesis? Station 2: Biogeography Notes Biogeography is the study of : Due to the introduction of new technologies, biogeography now includes the study of: Sickle cells are: Sickle cell is caused by: Sickle cell disease causes: What pattern did British doctor Anthony Allison notice? Dr. Allison hypothesized that the evolution of this gene must: Station 2 Questions 1. Do you think the information and map data support Allison’s hypothesis? Why or why not? 2. How would you test this hypothesis? Evidence for Evolution Station Lab Station 3: Molecular Homologies Notes Define homology:_________________________________________________________ Why is the protein cytochrome c an ideal molecule used in the study of evolutionary relationships?_________________________________________________________________________________________ ___________________________________________ What would you expect to see if species were more distantly related? ________________________________________________________________________ What would you expect to see if species were more closely related? ________________________________________________________________________ Organism A vs. Organism B Organism A vs. Organism C Number of amino acid differences Station 3 Questions 1. Which organisms did you choose to analyze? ________________________________ 2. Based on your analysis, hypothesize which two organisms are more closely related. _________________________________________________________________ 3. How would you further test your hypothesis? _________________________________________________________________ Station 4: Anatomical Homologies In Biology homology is defined as a: The trait may change over time depending on whether the variation provides: Scientists look for homologies as part of the: Scientists who have compared the skulls, teeth, and tusks of different elephant fossils hypothesize that: Station 4 Questions: 1. Do you think the illustrations support the hypothesis? Why or why not? 2. How would you test this hypothesis?
