AP BIOLOGY SEMESTER 1 EXAM REVIEW UNIT 1: MECHANISMS OF EVOLUTION Darwinian Evolution Evidence Paleontology, biogeography, embryology, comparative anatomy, homologous structures, analogous structures, vestigial structures, molecular biology, artificial selection Natural Selection Over-production of offspring, inherited variation, competition, adaptations, fitness, reproductive success of advantageous traits Stabilizing selection (human birth weight, extremes selected against - too small won?t survive, too big difficult birth), directional selection (pesticide resistance, peppered moth), disruptive selective (opposite of stabilizing), sexual selection (male competition, female choice)
