Looking at Evolutionary Relationships Name: Period ______Date : Laboratory Experience ## Worth ### Lab Minutes Bridge Place pictures up on the SMARTboard labeled. Objective: Use structural evidence to identify evolutionary relationships</p><p>Essential Question: What kind of evidence is used to determine relationships? How is it used?</p><p>Mini Lesson</p><p>P a g e | 1 Living Environment Student Work BSC Lesson # 11 So yesterday we learned that DNA directs the expression of proteins and those proteins in turn give us our traits. Why would those traits be important?</p><p>Work Period You will be working at different stations (4) to work to determine the relationship between these organisms using the evidence provided. </p><p>Summary What kind of evidence is used to determine relationships? How is it used?</p><p>Closing What could you use that would help you to determine a stronger relationship between these three specimens?</p><p>P a g e | 2 Living Environment Student Work BSC Lesson # 11 Independence Practice Article on the discovery of Ardi and the thought that he replaced “Lucy” as the missing link with questions.</p><p>Name: Period ______Date :</p><p>P a g e | 3 Living Environment Student Work BSC Lesson # 11 Name: Period ______Date :</p><p>Lab: Analyzing Evidence for Evolutionary Relationships</p><p>Part 1. Structural Evidence</p><p>Make observations of the specimens on the screen. Record below.</p><p>Question: Who do you think is most closely related? Why?</p><p>Prediction/Hypothesis: </p><p>Experimental Design: Procedure.</p><p>1. There are four stations at the tables on your side of the room. 2. At each station, observe the evidence provided and answer the questions found in the data section for each station. 3. You will have 10 minutes at each station then moved to the next. 4. Complete the data analysis and the evaluation.</p><p>P a g e | 4 Living Environment Student Work BSC Lesson # 11</p><p>Data Collection:</p><p>Station 1. Embryology</p><p>Look at the specimens of the human, chimpanzee, and Ardipithecus as they develop in the womb. Use this to determine which two are more closely related and why. Record below.</p><p>Hint: Use the traits of each embryo!</p><p>Station 2. Comparative Anatomy</p><p>Look at the different structures that have been provided to you for the chimpanzee, human, and the Ardipithecus. Based on what you observe, which two do you think are more closely related? Why?</p><p>Station 3. Fossils P a g e | 5 Living Environment Student Work BSC Lesson # 11</p><p>Look at the different fossils that have been provided to you for the chimpanzee, human, and the Ardipithecus. Based on what you observe, which two do you think are more closely related? Why?</p><p>Station 4. Vestigial Structures</p><p>Look at the different fossils that have been provided to you for the chimpanzee, human, and the Ardipithecus. Based on what you observe, which two do you think are more closely related?
