Morphological data can sometimes be misleading in terms of evolutionary relationships. Question: Why can morphological data be misleading? Think about convergent evolution/ environment and the whale, dolphin, hippo relationship)

Virtual Lab Lizard Evolution Virtual Lab hhmi Biolnteractive LIZARD EVOLUTION VIRTUAL LAB Answer the following questions as you finish each module of the virtual lab or as a final assessment after completing the entire virtual lab. Student Handout Module 1: Ecomorphs 1. At the beginning of the virtual lab, you were asked to sort eight lizards into categories. What criteria did you initially use to make your groups? Did you revise your criteria later? Why? 2. An adaptation is a structure or function that is common in a population because it enhances the ability to survive and reproduce in a particular environment. Provide one example and an explanation of one adaptation in the Anolis lizards. 4. What is an ecomorph? Provide one example from the virtual lab. 3. Provide one evolutionary explanation for why lizards living in the same part of the habitat (i.e., grass) would have similar characteristics. 5. How is an ecomorph different from a species? 6. Explain how a particular body feature…

Which of the following statements about homeobox (hox) genes is FALSE? Group of answer choices They direct the development of an overall body plan They DO vary greatly from species to species and are NOT “highly conserved” Subtle differences in hox gene action are responsible for physical differences in closely related species. They DO NOT vary greatly from species to species and ARE “highly conserved”

Question 11 Which of the following statements about homologous characters are true? (pick all that apply) homologous characters are the result of convergent evolution Homologous characters are not present in a common ancestor homologous characters have a similar underlying structure Homologous characters are the result of common descent Homologous characters are useful for making phylogenetic trees O 000

This is not graded!

Please number your answers 1-5 :) 1. Define comparative anatomy. 2. Define analogous structures. 3. What are vestigial structures 4. What is comparative biochemistry 5. How do each of these support the theory of evolution?

A scientist is studying two different species of fish. The table below shows various observa- tions that the scientist could have seen in the two different species of fish. Observation Number A B с 1 D 2 3 4 observation 1 observation 2 observation 3 Genetic Similarity observation 4 high low low high Function of Structure different same Which observation number would best support the claim that the two species have structural similarities, specifically as a result of convergent evolution? different same Form of Structure same different same different

Who is Charles Darwin? English naturalist whose scientific theory of evolution by natural selection became the foundation of modern evolutionary studies   4. Which animal are they studying on the Galapagos islands? Iguanas, giant tortoises, and finches.     5. What are they looking for on the finches?   6. What are the differences between the finches that the scientists notice?   7. How many ancestors did the finches come from?   8. What did they measure on the birds?   9. Which birds had the most trouble? Why?   10. What did they notice about the new generation of the bird’s beaks?   11. How did there become so many species of these birds with different sized beaks?   12. What did the Grants show that are the key to evolution in the Galapagos islands?   13.
