THIS IS Miscellaneous Scientists Populations Evolution Evidence Galapagos Natural Selection 100 100 100 100 100 100 200 200 200 200 200 200 300 300 300 300 300 300 400 400 400 400 400 400 500 500 500 500 500 500 The elimination of a species from Earth A 100 What is extinction A 100 Type of reproduction isolation where are separated by natural barriers such as rivers or mountains. A 200 What is geographic isolation A 200 Type of reproductive isolation where reproductive structures are physically incompatible A 300 What is mechanical isolation? A 300 Type of reproduction isolation where organisms breed at different times of the year. A 400 What is temporal isolation A 400 Theory that states natural disasters such as floods and volcanic eruptions have happened often during Earth’s long history. A 500 What is catastrophism? A 500 Lamarck would have reported that these animals stretched their necks to reach the leaves. B 100 What are giraffes? B 100 Came up with the classification system we still use today. B 200 Who is Linnaeus B 200 High birth rates & limited resources would force life & death competition B 300 Who is Malthus’ B 300 This scientist proposed the theory of evolution by natural selection. B 400 Who is Charles Darwin B 400 Proposed all living organisms evolved towards perfection and complexity. B 500 Who is Lamarck B 500 Made up of all alleles from all individuals in a population C 100 What is gene pool? C 100 Two sources genetic variation comes from C 200 What are mutations and recombination C 200 The movement of alleles between populations. C 300 What is gene flow? C 300 DAILY DOUBLE C 400 Two different types of genetic drift C 400 The bottleneck effect and founders effect C 400 Type of sexual selection where females choose the male based on bright colors, dancing, or singing C 500 What is intersexual selection C 500 This means coming from ancestors with changes. D 100 What is descent with modifications? D 100 Vertebrate forearms are said to be this type of structures. D 200 What are Homologous Structures D 200 These are structures that are non functional in a present day organism, that were once functional in an ancestor. D 300 What is vestigial? D 300 Structures that perform a similar function, but are not similar in origin D 400 What are analogous structures? D 400 A DNA sequence that resembles a gene but seems to have no function (like vestigial structures) D 500 What are pseudogenes? D 500 The Galapagos are these types of land masses. E 100 What is islands? E 100 The Galapagos is nearest to this continent. E 200 What is South America? E 200 These large reptiles expressed different characteristics related to the vegetation they consumed. E 300 What are tortoises? E 300 Finches had different types of beaks adapted to their E 400 What is type of food consumed? E 400 The fossil evidence Darwin observed showed… E 500 Species change over time. E 500 Natural Selection can only act on… F 100 Existing variation F 100 Natural selection is sometimes referred to by this four-word description. F 200 What is “survival of the fittest”? F 200 This is a term that refers to any beneficial trait. F 300 What is an adaptation? F 300 Humans use this process to produce new types of cattle, plants, dog breeds etc. F 400 What is artificial selection? F 400 In order for natural selection to occur, the population must have a range of differences known by this term. F 500 What is variation? F 500 The Final Jeopardy Category is: Natural Selection Please record your wager.
