TEKS 7(A): analyze and evaluate how evidence of common ancestry among groups is provided by the fossil record, biogeography and homologies, including anatomical, molecular and developmental; TEKS 7(B): analyze and evaluate scientific explanations concerning any data of sudden appearance, stasis, and sequential nature of groups in the fossil record; TEKS 7(C): analyze and evaluate how natural selection procedures change in populations, not individuals;

2 TEKS 7(D): analyze and evaluate how the elements of natural selection, including inherited variation, the potential of a population to produce more offspring than can survive, and a finite supply of environmental resources, result in differential reproductive success; TEKS 7(E): analyze and evaluate the relationship of natural selection to adaptation and to the development of diversity in and among species; TEKS 7(F): analyze and evaluate the effects of other evolutionary mechanisms, including genetic drift, gene flow, mutation and recombination. Listen and Look Here is a list of key terms you will hear and see during the reading and videos. Get to know them! VOCAB QUIZ: THURSDAY, MARCH 1 Evolution: change in a species over time Natural Selection: Mechanism by which individuals that have inherited beneficial adaptations produce more offspring on average than do other individuals. Population: all of the individuals of a species that live in the same area. Homologous structure: body part that is similar in structure on different organisms but performs different functions. Analogous structure: body part that is similar in function as a body part of another organism but is structurally different. Embryology: study of embryos (stage of development after the fertilized cell implants into the uterus but before the cells take on a recognizable shape). Vestigial structure: the remnants of a structure that is no longer needed. Fossil Record: history of life as documented by fossils. Adaptation: inherited traits that is selected for over time because if allows organisms to better survive in their environment. Paleontology: study of life using the fossil record. Biogeography: study of the distribution of organisms around the world. Variation: the variety of gene combinations that exist within a population. Artificial Selection: process by which humans modify a species by breeding it for certain traits. Fitness: an organism s ability to survive and produce viable, fertile offspring. Convergent evolution: evolution toward similar characteristics in unrelated species, resulting form adaptations to similar environmental conditions. Divergent evolution: evolution of one or more closely related species into different species; resulting from adaptations to different environmental conditions. Coevolution: process in which two or more species evolve in response to changes in each other. Extinction: elimination of a species from Earth. Adaptive Radiation: process by which one species evolves and gives rise to many descendent species that occupy different ecological niches. Charles Darwin: scientist who identify the process of natural selection

3 Recall and Review: ANSWER ALL THE QUESTIONS IN COMPLETE SENTENCES. Use the videos and your textbook to help you answer the following questions in your binder. A. Chapter Describe the difference between a variation and an adaptation. Variation Adaptation 2. Explain why tortoises of the same species look different. 3. List two things Darwin learned from his trip to the Galapagos. B. Chapter State the four main principles of natural selection. 5. Briefly explain how each of the above principles is necessary for natural selection to occur. C. Chapter Describe the four sources of evidence for evolution upon which Darwin based his ideas on common ancestry. 7. Why vestigial structures are considered critical evidence of evolution? Give an example of a vestigial structure.

4 8. Describe the difference between homologous and analogous structures. Homologous Analogous D. Chapter Explain how paleontology is important to evolutionary biology. 10. How has molecular genetics, combined with paleontology, added to our understanding of evolution? 11. Describe how similar protein comparisons of cells in two species can suggest a close evolutionary relationship. E. Chapter Why does genetic variation increase the chance that some individuals in a population will survive. 13. Describe two main sources of genetic variation. F. Chapter Explain what it means to say that natural selection is not random. 15. How does coevolution shape two species over time?

5 16. Describe the difference between convergent and divergent evolution. Convergent Evolution Divergent Evolution G. Chapter Why are so few complete fossils discovered? H. Chapter What is the usefulness of categorizing Earth s history into the geologic time scale? Sample Questions 19. The loss of habitat in a forest region has caused some plant species to become extinct, while others survive. The process by which some plant species survive and others do not in a changing environment is best explained by a. Natural selection b. Law of segregation c. Biological magnification d. Alternation of generations 20. Which of the following is evidence to support the idea that two different species might have a common ancestor? a. Their fossil were discovered in the same location b. Many of their genes are the same c. Their methods of respiration are alike d. They use the same means of locomotion 21. The bones in the wings of a bat are the same as the bones found in the paws of raccoon, though their function is quite different. The similarity is evidence that the bat and the raccoon a. Hunt for the same prey b. Live in the similar habitat c. Are about the same size d. Share a common ancestor 22. Which of the following is biochemical evidence for evolution? a. Embryonic human hemoglobin is different from adult human hemoglobin. b. Hemoglobin in humans can vary between different individuals. c. Human hemoglobin is more similar to chimp hemoglobin than mouse hemoglobin. d. Human hemoglobin is different than mouse hemoglobin.
