BIOL 1013 Lecture Notes - Lecture 8: Mantis Shrimp, Allele Frequency, Allele
Document Summary
Change of allele frequency in populations, generation to generation. You + others = new humans = change in allele frequency. Detectable by examining the populations gene pool. Theories has evolved over centuries: aristotle, buffon, hutton, cuvier, lamarck, lyell, darwin and wallace, patterns in fossils, sedimentation, discovering species that no longer exist (dinosaurs, species that resemble current species (mantis shrimp relative) Cuvier"s principle of superposition: fossils of extinct species suggest that living organisms are descent from common ancestors. Lamarck proposed testable ideas about how species change; set the stage for darwin & Darwin took notes on 14 species of finches, all similar but with different beak anatomy: island to island, beaks would differ based on food supply. Evolutionary theory continued to expand: mendel"s plants- inherited traits, watson and crick- dna structure, tectonic plates, different populations, large-scale genomes- phylogenetics (study of genetic relationships throughout time)
