Unit 8: Evolution Topic: Origin of Life Aim # _____:____________________________________________________________________________________ 1) What were the conditions on earth 4.5 billion years ago? 2) What was an important energy source for life to begin on Earth? 3) Where did life begin? 4) What were probably the first organisms on earth? 5) Where did the oxygen in the atmosphere probably come from? 6) Aerobic Organisms: 7) How do scientists explain this change from simple to more complex organisms? Page 1 Unit 8: Evolution 8) What is a theory? 9) What is the evidence that supports the theory of evolution? 10) How do we know that we developed from organisms distinctly different from us? 11) The fossil record shows… 12) What else do we learn from fossils? 13) What is a species? Page 2 Unit 8: Evolution 14) What is speciation? 15) Evolutionary Tree: 16) What organisms are our closest relatives? Why? Page 3 Unit 8: Evolution Topic: Adaptive Variation Aim # _____:____________________________________________________________________________________ 1) What is variation? 2) What produces variation? 3) Why are variations important to a population? 4) The Peppered Moth Example: Page 4 Unit 8: Evolution 5) What is an adaptation? 6) What is an Adaptive Variation? 7) What would happen to a population with variation if the environment changed? 8) What would happen to a population that did not have variation and the environment changed? 9) What is the theory of evolution? Page 5 Unit 8: Evolution Topic: Natural Selection Aim # _____:____________________________________________________________________________________ 1) How does evolution occur? 2) Who was Charles Darwin? 3) Natural Selection: 4) Natural Selection vs. Artificial Selection: Page 6 Unit 8: Evolution 5) Conditions that are vital for natural selection: a) Overproduction: b) Variation: c) Best Adapted to Survive: Adaptive Value- d) Struggle for Survival: 6) Conditions that lead to evolution: Page 7 Unit 8: Evolution 7) Patterns of Change: a) Gradualism- b) Punctuated Equilibrium- 8) Examples of Natural Selection: a) Industrial Melanism: c) Antibiotic/ Pesticide Resistance: The antibiotic is the selecting agent Resistant Bacteria Antibiotic X Why should we be concerned with antibiotic overuse? Page 8 Unit 8: Evolution Topic: Comparative Studies Aim # _____:____________________________________________________________________________________ 1) How do we know we are related to chimps and gorillas? 2) What are comparative studies? 3) Why do scientists do comparative studies? 4) a) Who are we closely related to? b) Who are we distantly related to? 5) What are the types of comparative studies? 6) What is comparative anatomy? 7) What are homologous structures? 8) What are vestigial structures? Page 9 Unit 8: Evolution 9) What are analogous structures? Insect Wing 10) What is Divergent Evolution? 11) What is Convergent Evolution? 12) When do these types of evolution occur? 13) What is comparative embryology? Page 10 Unit 8: Evolution 14) What is comparative biochemistry? 15) What is the idea of common ancestry? 16) What are the results of genetic variation? Page 11 Unit 8: Evolution Topic: Geographic and Reproductive Isolation Aim # _____:____________________________________________________________________________________ 1) a) What is a species? b) What is speciation? c) What is a population? 2) What was Darwin’s explanation for evolution? 3) What is Geographic Isolation? Page 12 Unit 8: Evolution 4) How does Geographic Isolation lead to speciation? 5) Darwin’s Finches are an example of Geographic Isolation: 6) What is adaptive radiation? Page 13 Unit 8: Evolution 7) What is reproductive isolation? 8) How long does evolution take? Page 14 Unit 8: Evolution Topic: Taxonomy Aim # _____:____________________________________________________________________________________ 1) What is taxonomy? 2) What are the subcategories? 3) How do scientists universally name organisms?
