Slide 13 Artificial Selection Slide 14 What is the name of the book that Darwin wrote? Slide 15 The Origin of Species Slide 16 Hutton & Lylle both said what about the formation of the earth? Slide 17 The earth is millions of years old/the earth was formed by geologic forces Slide 18 The 2 guys that came up with a mathematical equation that can predict allele frequencies? Slide 19 Hardy & Weinberg Slide 20 All of the genes in a population is called? Slide 21 Gene Pool Slide 22 Name 2 sources of genetic variation. Slide 23 Mutations Crossover (Gene Shuffling) Slide 24 Any organ that is reduced in function that may have been used by an ancestor? Slide 25 Vestigial Organ Slide 26 Body structures that are similar in structure and function? Slide 27 Homologous Structures Slide 28 Body structures that are similar in function but different in structure are called? Slide 29 Analogous Structures Slide 30 A trait controlled by more than one gene is called? Slide 31 Polygenic Trait Slide 32 A random change in allele frequencies over the generations is called? Slide 33 Genetic Drift Slide 34 When allele frequencies remain constant it is called? Slide 35 Genetic Equalibrium Slide 36 What occurs when allele frequencies in a group of migrating individuals are by chance not the same as that of the original population? Slide 37 Founder Effect Slide 38 What effect can happen when a populations numbers undergoes a drastic decrease? Slide 39 Bottleneck Effect Slide 40 Where individuals with favorable traits survive & pass on those traits to their offspring? Slide 41 Natural Selection Slide 42 When natural selection favors one extreme phenotype or the other. Slide 43 Directional selection Slide 44 When natural selection doesnt favor either extreme phenotype. Slide 45 Stabilizing selection Slide 46 When natural selection favors both extreme phenotypes. Slide 47 Disruptive selection Slide 48 What are the 5 conditions to maintain genetic equilibrium Slide 49 1.Must be random mating 2.Must have a large pop. Size 3.No movement of genes 4.No mutations 5.No Natural selection Slide 50 The evolution of a new species Slide 51 Speciation Slide 52 When 2 populations become separated by a geographic barrier (river, mtn. etc) Slide 53 Geographic Isolation Slide 54 When a species doesnt recognize another species as a mate because it didnt do the correct mating dance or call or make the correct display Slide 55 Behavioral Isolation Slide 56 When 2 species mate at different times Slide 57 Temporal Isolation Slide 58 Slide 59 When members of a population can no longer interbreed with the rest of the population is called? Slide 60 Reproductive Isolation Slide 61 Large scale evolution that takes place over a long period of time Slide 62 Macroevolution Slide 63 What percentage of species that lived on earth have become extinct? Slide 64 99% Slide 65 Where two or more species originate from one species called a common ancestor. Slide 66 Divergent Evolution Slide 67 Where 2 different species evolve in response to one another. Slide 68 Coevolution Slide 69 What is it called when 2 different species inhabit similar environments and evolve similar traits. Slide 70 Convergent Evolution
