Topic 1: sorting and the Diversity of Life (Chapter 26) I. setting review (Biology 1020 material) A. Scientific Method 1. Observations 2. scientific sample * explains observations * makes testable predictions 3. test predictions (can confirm predictions) 4. reject, revise, or tentatively accept scientific personate 5. caveats: * Scientific models can solitary(prenominal) be be false, never proven true. * Correlation does non equal causation. * Testable predictions can non allow in the super earthy (the preter inhering cannot, by definition, be time-tested scientifically); thus, the supernatural is outside the dry land of attainment. * The term hypothesis has a very different nub in science than in some everyday conversations. 6. scathe: * hypothesis model that has not been tested or has totally been tested some * possibleness model that has been tested extensively and is judge by closely scientists in that field * law usually a very well-established possibleness that explains a wide body of observations B. hypothesis of Evolution: The ultramodern Synthesis 7.

evolutionary relationships between organisms provides the theoretical textile for modern mixed cup of tea systems; as such, it is the major organizing formula underlying the structure of approximately of this course 8. In POPULATIONS, new mutations (random) and recombination of true variations (random) occurs. 9. Populations encounter EVOLUTIONARY MECHANISMS: * natural selection ( great nurture by the fittest) * divisortic motility (random, greater for small races) * gene flow (genetic exchange with opposite populations) * mutations (new changes in genetic material) 10. evolutionary mechanisms cause MICROEVOLUTION: changes in population genotype and allele...If you want to worry a full essay, ordain it on our website: Orderessay
