Topic 1: Classification and the Diversity of Life (Chapter 26) I. backdrop review (Biology 1020 material) A. Scientific Method 1. Observations 2. scientific sample * explains observations * makes canvasable predictions 3. test predictions (can confirm predictions) 4. reject, revise, or tentatively accept scientific posture 5. caveats: * Scientific models can solitary(prenominal) be proved false, never proven true. * Correlation does non equal causation. * Testable predictions cannot include the super earthy (the preternatural cannot, by definition, be tested scientifically); thus, the supernatural is outside the state of attainment. * The term hypothesis has a very different substance in science than in some everyday conversations. 6. equipment casualty: * hypothesis model that has not been tested or has single been tested some * possibleness model that has been tested extensively and is accepted by closely scientists in that field * justness usually a very well-established possibleness that explains a large-minded body of observations B. Theory of Evolution: The ultramodern Synthesis 7.

evolutionary relationships between organisms provides the theoretical framework for modern mixed bulk systems; as such, it is the major organizing principle underlying the structure of nigh of this course 8. In POPULATIONS! , new mutations (random) and recombination of current variations (random) occurs. 9. Populations encounter evolutionary MECHANISMS: * natural selection ( great reproduction by the fittest) * transmittable drift (random, greater for small populations) * gene flow (genetic counterchange with other populations) * mutations (new changes in genetic material) 10. Evolutionary mechanisms cause MICROEVOLUTION: changes in population genotype and allele...If you want to get a near essay, order it on our website: OrderCustomPaper.com
