PPT-Lesson # 2: Evolution

Evidence for Evolution We will look at major evidence supporting theories of evolution Fossil Record Comparative Anatomy Biogeography Biochemistry Evidence Supporting Theories of Evolution . Assessment Statements. Outline. . the method for dating rocks and fossils using radioisotopes, with references to . 14. C and . 40. K.. Define half-life. Deduce the approximate age of materials based on a simple decay curve for a radioisotope.. Scientific Theory. Social use of the word “theory”. Not the same as in science. Implies a hunch or a casual guess. Scientific Theory. 1. Highly probable explanation based on vast collections of scientific data. 3. Objectives. Advertising’s Role in Capitalism. Role in Manufacturing & Retailing. Know Era’s & Association with Culture. Identify Evolutionary Forces. The Value of an Evolutionary Perspective. THE ORIGIN AND EVOLUTION OF MICROBIAL LIFE. HOW DID LIFE ORIGINATE?. SPONTANEOUS GENERATION. LIFE ARISING FROM NON-LIVING MATTER. LONG BELIEVED AS THE ACCEPTED EXPLANATION OF ORIGINATION OF LIFE. EXPERIMENTS EVENTUALLY SHOWED IT TO BE IMPOSSIBLE. Evidence of Evolution. Essential Questions. What is the anatomical evidence of evolution?. How are fossils used as evidence of evolution?. What evolutionary evidence do we have from the field comparative embryology?. Which one?. There are 3 great universal questions. 1) Where did I come from?. 2) Why am I here?. 3) Where am I going?. The answer to the last 2 questions are dependent upon the answer to the first question. . What do we use in order to determine evolutionary relationships?. Fossil Record. Anatomical Evidence. Molecular Evidence. Embryological Evidence. Evidence for Evolution. Fossil Record. Evidence for Evolution. Mechanisms of concerted evolution. Unequal cross-over. Gene conversion: non-reciprocal transfer of information between homologous sequences; the main mechanism invoked to explain concerted evolution. Tricia Radojcic, Ph.D.. Chaparral High School, Murrieta, California . and. Theodore Garland, Jr., Ph.D.. University of California, Riverside. Supported by National Science Foundation,. American Physiological Society,. 4b.4. The Triple-Note-Tote. Topic. Details. Mnemonic. Triple-Note-Tote. Objectives. Recognize the importance of taking effective notes for remembering information. Organize ideas from an article using the Triple-Note-Tote. of . the Red . Queen. CfE. . Advanced Higher Biology. Unit . 2: . Organisms and Evolution. SQA mandatory key information. A change in the traits of one species acts as a selection pressure on the other species. . Evolution. – when a species of plants or animals adapts to their environment in order to survive over a long period of time. Key points!. Species. Plants or Animals. Adaptations. In order to survive. Evolution 9/11. Obj. TSW learn form mistakes made on the quiz, and take notes about evolution after the Environmental Science Current Events. P. 34NB. Make a food chain for the following organisms showing the energy arrows and the . . The process by which organism change over time. Based on science, not opinion.. Darwin. :. Evolution is descent with modification. Evolution. :. changes through time. Species accumulate difference.
