Name _____________________ EVOLUTION UNIT (CH 22-25) Objectives: Early evolution of life What are the current biological models for the origins of biological macromolecules? What are the current models for the origins of prokaryotic and eukaryotic cells? Evidence for evolution What types of evidence support an evolutionary view of life? Mechanisms of evolution What is the role of natural selection in the process of evolution? How are heredity and natural selection involved in the process of evolution? What mechanisms account for speciation and macroevolution? What different patterns of evolution have been identified and what mechanisms are responsible for each of these patterns? (Tentative) Agenda: Students will be expected to come to class with notes related to the topic for the day. CH25 Fri 2/21 Describe the conditions on primitive earth that led to the origin of complex molecules and eventually to protobionts. Describe how the evolution of energy sources of primitive cells had a major impact upon atmospheric conditions. Describe the evidence for the origins of eukaryotic cells. CH 22 Mon 2/24 Compare the evolutionary theories of Lamarck and Darwin. Describe the different types of evidence of evolution and give an example of each. CH 23 Tues 2/25 List Darwin’s arguments for natural selection. Explain the following types of selective pressures on populations and be prepared to give an example of each: stabilizing, directional, disruptive, and sexual. Wed 2/26 Describe sources of genetic variation in alleles and the conditions that may change allele frequencies. Thurs 2/27 Be prepared to use the Hardy-Weinberg equation to solve problems to determine allele frequency in populations. Fri 2/28 Describe the conditions that lead to speciation and the maintenance of individual species. What are the major patterns of evolution? Compare the theories of gradualism and punctuated equilibrium. CH23 CH 24 Mon 3/3 Tues Toothpick Fish Wed 3/5 Unit Exam Buffer Day (?) Notes may be checked daily. The FINAL DAY for NOTE CHECKS will be: Tues - Mar 4 A complete set of notes (worth 100 pts) will be Due Mar 5 (Test Day) There will be at least two (2) in class writing prompts (each worth 30 pts) Please include this sheet as a COVER SHEET when you submit your complete set of notes.
