BIOL 211 Lecture Notes - Lecture 4: Pesticide Resistance, Evolutionary Algorithm, Selective Breeding
Document Summary
Health artificial selection for better crops & livestock pesticide resistance drug resistance emerging diseases understanding disease. Intellectual stepping-stones to developing a theory of evolution. Lamarck and the first comprehensive theory of evolution. Species improve over generations striving for perfection and to move up the chain of being. Characteristics acquired during lifetime are passed to offspring. Results in a conflict when there is a finite set of resources. 1831 1836: from 22 to 27 years old. Volcanic islands far off the west coast of ecuador. All inhabitants are descended from species that arrived on islands from elsewhere. Having their shells in front thick and turned up like a spanish saddle . Santiago island tortoises rounder, blacker, and have a better taste when cooked. Exhibit traits common to both an ancestral group and its derived descendant group. Help us to understand how new traits and groups arose. Also: antibiotic, pesticide and herbicide resistance early stages of speciation.
