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

evolutionary relationships between organisms provides the theoretical framework for modern mixed purse systems; as such, it is the major organizing principle underlying the structure of most of this course 8. In POPULATIONS, new mutations (rand! om) and recombination of current variations (random) occurs. 9. Populations encounter evolutionary MECHANISMS: * natural selection ( great reproduction by the fittest) * ancestral drift (random, greater for small populations) * gene flow (genetic convince 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 wide essay, order it on our website: OrderCustomPaper.com
