1 Thursday, January 14 Teaching Point: SWBAT. assess their knowledge to prepare for the Evolution Summative Assessment. (TOMORROW) Agenda: 1. Show Hinsz your completed Review WS 2. Discuss answers to Review WS 3. Self Assess

2 Vocabulary Review Law d Theory e Population c Evolution a Natural Selection f Artificial Selection b a. a change in a species over time. b. the breeding of plants and animals to produce desirable traits. c. a group of individuals of the same species that live in the same area. d. an observation that happens every time under a certain set of conditions. e. a broad explanation of natural events that is supported by strong evidence. f. process by which individuals that are better suited to their environment survive and reproduce.

3 adaptation c A. organisms are members of same species if they can mate and produce fertile offspring. speciation f B. branching diagram showing how organisms biological species a are related through evolution. C. a trait that helps an organism survive and phylogeny e reproduce. cladogram d D. diagram that show the evolutionary relationships among a group of organisms. phylogenetic tree b E. evolutionary history of a species. F. formation of a new species.

4 A. Traits that evolved in a common ancestor of two groups. derived structure b B. characteristics that appear in recent analogous structure e parts of a lineage but not in its older members. ancestral structure a C. a structure that is present in an homologous structure d organism but no longer serves its original purpose. vestigial structure c D. structures in different species that are similar because of common ancestry. E. similar features evolved through convergent evolution

5 1. There are 4 pieces of evidence that supports the theory of evolution. What are they and give examples of each? 1. Fossils - skulls and bones of the modern horse and dawn horse 2. Embryology- embryos of fish, salamander, tortoise, chicken, rabbits, and humans are all very similar in the beginning phases. 3. Comparative Anatomy a. Homologous structures- similar anatomy, different function- human arm & fin of a whale b. Analogous structures- different anatomy, similar function- butterfly wing & bird wing c. Vestigial structure- structures that no long have a function- Human Appendix 4. Molecular Biology- Similarities in DNA and proteins

6 2. There are three different types of anatomical structures. What are they and give an example of each. 1. Homologous structures- similar anatomy, different function- human arm & fin of a whale 2. Analogous structures- different anatomy, similar function- butterfly wing & bird wing 3. Vestigial structure- structures that no long have a function- Human Appendix

7 3. Natural selection is one process that can change a population over time. Give examples of 3 others. Disease Predation Natural Disasters Mutation Reproduction

8 4. Draw a graph of stabilizing, directional, and disruptive selection. Directional Stabilizing Disruptive

9 5. Make a cladogram using the following organisms and structures. Cells Backbone Legs Hair Opposable Thumb Slug x Catfish x x Frog x x x Tiger x x x x Human x x x x x

10 thumb hair legs backbone cells cells backbone, legs, hair, thumb

11 Self Assess! Rate yourself on each of the following. 1- I need to study! 4- I got this! Knowledge of vocabulary terms Evidence of Evolution Types of Anatomical Structures Factors that cause Evolution Directional, Disruptive, and Stabilizing Selection Making a Cladogram Now What? Make a study plan. What do you need to spend the most time on? The least?
