How does embryology provide evidence for evolution? 3. How do homologous and vestigial structures provide evidence for evolution? 4. What could be possible for some species belonging to the same family to be presently living in various locations on Earth? You can furthel support your answer with an example.

Identify the type of evolution being described.

Only answer number 2 only.

PERFORMANCE TASK: 1. Go online. Choose a group of organisms you are interested to work with (e.g. invertebrates); 2. In tabular form, list all the characters. Evaluate the characters (whether primitive or derived). 3. Remember that in building your cladogram, use only shared derived characters. 4. Construct your own cladogram.

Instruction: Explain your answer. Scientific Thought: "In evolutionary relationships using the evidences of evolution, the more closely related the species are, the more similar their DNA sequences. Provide concrete evidence through illustration to prove your answer. You may use other ways to show your answer.

Match the type of evidence to its description. Column I 1. In DNA sequencing, the more closely related two organisms are, the more similar their DNA. Column II A. Paleontology (Fossil Records) B. Genetics C. Geography D. Comparative Anatomy E. Embryology F. Adaptation G. Variation 2. Different habitats favor different traits and can establish separate populations that have a common ancestor. 3. Different organisms share similar structures that have very different functions, or have remnants of structures or organs that had a function in the past. 4. Fossil organisms found in bottom (older) layers are more primitive than those in the upper (newer) layers. 5. During the early stages of life, embryos of very different organisms appear to be very similar. As they continue to develop, they become increasingly different.

Exercise 3. Create a phylogeny to try to understand the evolutionary history of mammals related to the giant panda using the gene Leptin. Introduction: Did you know that it is required that every gene that is sequenced and published must be made fully accessible on the internet. What that means is you can look up any gene online. Today we will use the NCBI website: The National Center for Biotechnology Information to first find a gene in giant Pandas and then we will use a feature on the NCBI website called BLAST which measures the degree of gene sequence similarity between various types of organisms. Once we have identified these gene sequences we will use them to build a phylogeny to figure out which animals are most closely related to giant Pandas. 1. First make a guess and label this phylogenetic tree to include: Giant Pandas, Bears, Sea Lions and Cats. Showing which are most closely related to one another: 1 2-Now do a search on the gene Leptin. What is its function? Regulation of…

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.

PART II. COMPARATIVE ANATOMY AND EMBRYOLOGY EVIDENCE > Using the information in the Reading file part Il and textbook reading, answer the following questions: 1. Whales possess vestigial organs in the form of pelvic girdle and hind limb bones. How would you explain this? Page 3 of 6 Evolution Lab Exercise Report (by Dr. Lapik) 2. How can you explain that, while forelimbs of bats and human arms are used for vastly different purposes, they do have similar anatomy? 3. How would you explain the presence of gill slits in embryos of animals that do not form gills?

INSTRUCTION • Answer the question properly • Do not copy here in Bartleby or Google. QUESTION 1. Think of a trait, for example color or taste that you would want another organisms to posses such trait, how are you going to do it?

Practice(not graded) There exist several categories of evidence that lend credence to the interrelated nature of all organisms alive today.  Describe two (2) pieces of evidence that support the theory of evolution (and the notion of a universal common ancestor).

Becoming Human worksheet Part I: “First Steps” What is the significance of the discovery of a fossil named Salaam (or “peace” in Ethiopian)?     2. Roughly when was Salaam living and how do we know this?     3. What are the comparisons made between chimpanzees and Australopithecus and how are they significant?       4. What was the climate/environment of Africa like many millions of years ago (say, 6 mya)?     5. According to biomechanist Daniel Lieberman, why did human ancestors become bipedal (walked upright)?     6. What is the Molecular Clock and how does it work?       7. What was the significance of the discovery of Sahlenthropus tchadensis?         8. What evidence is used to suggest that brain development was happening in early human ancestors?         9. What was the climate of Africa like roughly 3 million years ago to 1 ½ million years ago?       10. How are these latest discoveries being used to challenge traditional conceptions of human evolution?

Name To be Submitted on: Time Frame: EVOLUTION At the end of this lesson, you will be able to describe general features of the history of life on Earth, including generally accepted dates and sequence of the geologic time scale and characteristics of major groups of organisms present during these time periods; and explain the mechanisms that produce change in populations from generation to generation (e.g., artificial selection, natural selection, genetic drift, mutation, recombination) TOPIC: Learning Competencies: Earth formed 4.6 billion years ago. Life first appeared on Earth about 4 billion years ago. The first life forms were microscopic, single-celled organisms. From these simple beginnings, evolution gradually produced the vast diversity of life today. In this lesson, you'll learn about the history of life from its origins until now. You'll learn that living things had to cope with some astounding changes. Giant meteorites struck Earth's surface. Continents drifted and…

INSTRUCTIONS: 1. On the branches of the phylogenetic tree on the back side of this worksheet, write in a unique derived trait (Autapomorphy), either anatomical or behavioral, that is used to distinguish each primate subgroup from the other taxa of primates. The points where the derived traits should be entered are labelled A1 - A6 and a written description of what is expected for each appears below and to the right of the tree. 2. On the trunk of the phylogenetic tree write in a shared derived trait (Synapomorphy) that unifies the branches (clades) of the tree which sit to the right of the trait marker (S1-S5). Again these traits can be either anatomical or behavioral and a written description of what is expected for each appears below and to the right of the tree. For both #1 and #2 you should write in at least one trait for each trait marker (A1-A6 and S1-S5) that appears on the phylogenetic tree. Make sure all entries are detailed enough to differentiate taxa and written legibly. If…
