Document Summary
The modern synthesis of evolution - how it works at the level of phenotypes genes & populations. Linear sequences of amino acids (building blocks of cells)\ y y each protein has specific function determined by blueprint stored in dna. Dna with one dna strand serving as a template y translation - trna - transfer rna information adapter molecule. Mutation - y error or change in a nucleotide sequence y randomly occurring process y. Somatic cell vs. gamete cell mutation, are relevant to evolutionary anthro. Can be neutral, harmful, or rarely beneficial to the organism. 3 important outcomes: y meaning genetic drift y random changes in gene pool over time y: reduces within pop. Genetic variation: more likely to effect small pop. Gene flow - y movement of genes btwn pop. y 2 important outcomes. Genetic variation: eventually reduces btwn pop genetic variation.
