1 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.What do you think of when you hear the word evolution? 2.What do you think the phrase “survival of the fittest” means?

2 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.How would you describe the relationship between natural selection and evolution? 2. During his voyage on the Beagle, Charles Darwin made many observations where? ` Natural selection is one mechanism of evolution On the Galapagos Islands

3 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.The species of finches Charles Darwin found on the Galapagos Islands displayed what kind of structural adaptation? 2.Why might Darwin have hesitated to publish his concepts of evolution by natural selection? The birds’ different-shaped beaks He felt like his findings could be controversial to many people.

4 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.Lamarck’s theory was false, but why was it significant to science and the study of evolution? 2.The hypothesis that species change over time by natural selection was proposed by… He was the first to believe the species change over time Charles Darwin

5 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.Why are bird wings and reptile forelegs evidence of evolution? 2.Similar features or structures molded by natural selection in different species are what kind of structures? 3.An adaptation is an inherited characteristic that can be… Homologous structures indicate a common ancestor. Analogous structures Physical or behavioral

6 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.Natural selection is the only mechanism of evolution that will lead to… 2.A snake pelvis is an example of a. structure. 3.The endosymbiotic theory is an example of the origin and evolution of… Adaptation Vestigial Eukaryotes

7 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.What is camouflage and how is it used by organisms? 2.What type of selection favors average phenotypes? 3.Human DNA is more similar to chimp DNA than mouse DNA. What kind of evidence of evolution would this be? Allows organisms to become almost invisible to predators. Helps the organism survive by blending in with the environment. Stabilizing selection Biochemical

8 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.True or False: Species that have similar physical characteristics support the hypotheses that these species originated from a common ancestor. 2.Information on genetics and.now provide compelling evidence of evolution that was not available to Darwin. True Biochemistry

9 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.What was the main evidence of evolution in Darwin’s time? 2.What is required from natural selection? 3.A farmer selecting what animal he wants to breed would be considered what type of selection? Fossils There must be variation among the members of a population. Artificial selection

10 Please come in and sit in your seat! Once in your seat, please answer the warm-up questions! 1.If a structure, such as a bird’s and bee’s wings, have the same function but different structure, what kind of structure is this? 2.True of False: Dark moths surviving on a dark background and able to reproduce is an example of strong fitness. 3.Members of a species move to a different place and cannot mate anymore with the original population, what is this called? Analogous True Reproductive isolation
