A 100 What is “The Origin of Species”? A 100 A rival theory that characteristics acquired during a lifetime could be passed on to offspring was proposed by this man. A 200 Who is Lamarck? A 200 This phrase refers to Darwin’s idea that all organisms have descended from a common ancestor. A 300 What is descent with modification? A 300 This term describes the idea that though a bat wing, an elephant foot and a person’s hand look different outside, they look very similar inside and are derived from a common ancestor. A 400 What is homologous? A 400 The evolutionarily left over but unused structures, like the human appendix or leg bones in whales are called this. A 500 What is vestigial? A 500 Change in the genetic makeup of a population. B 100 What is microevolution? B 100 Greater in small populations than large ones, the unpredictable fluctuation in allele frequencies. B 200 What is genetic drift? B 200 The result of a few members of a population surviving a catostrophic change in the environement. B 300 What is the Bottleneck Effect? B 300 The result of a few members of a population becoming isolated from the original population and establishing their own. B 400 What is the TV show Lost? No, really, it’s the Founder Effect B 400 With this (name and formula please) it can be determined whether or not a population is evolving by checking allele frequency. B 500 What is p2 + 2pq + q2 or the Hardy Weinberg theorem? B 500 Given credit for describing evolution as a result of Natural Selection C 100 Who is Charles Darwin? C 100 The condition for traits to have in order for Natural Selection to act on them. C 200 What is heritable? C 200 Economist responsible for the idea that populations place greater demand on resources than environment can supply. C 300 Who is Malthus? C 300 DAILY Place A Wager DOUBLE C 400 Along with Natural Selection and Genetic Drift, one of the 3 major influences bringing about Evolutionary change. C 400 What is Gene Flow? C 400 Along with stabilizing and disruptive, one of the three modes of selection in adaptive evolution. C 500 What is directional? C 500 Evolutionary change at the species level, like the appearance of hair or limbs. D 100 What is macroevolution? D 100 Indicates species breed at different times of day or year and thus prevents them from mating. D 200 What is temporal isolation? D 200 This term refers to a population forming a new species because of geographical isolation from the parent population. D 300 What allopatric speciation? D 300 This term refers to apparent periods of little evolutionary change interrupted periodically by rapid change. D 400 What is punctuated equilibrium? D 400 Sympatric speciation can be accomplished through nondisjunction in meiosis by forming these type of plants. D 500 What is autopolyploid? D 500 Evolutionary changes above the species level. E 100 What is macroevolution? E 100 These structures evolve for one purpose but get co-opted for another. E 200 What are exaptations.? E 200 The “control genes” lay out the general plan for bodies, i.e., put the head here, put the tail there. E 300 What are homeotic or Hox genes? E 300 This field of study combines evolution and developmental biology to show how small genetic changes can turn into large morphological changes. E 400 What is “Evo-Devo”? E 400 Refers to the different growth rates of different body parts, like the jaw versus the skull. E 500 What is allometric growth? E 500 The order of taxonomy between genus and order. F 100 What is family? F 100 Comparing DNA and RNA to infer evolutionary relationships. F 200 What is molecular systematics. F 200 A group of species that includes an ancestral species and all its descendants. F 300 What is a clade? F 300 Each categorization at a level of classification. F 400 What is a taxon? F 400 The idea that the simplest explanation in line with the facts should be the first investigated F 500 What is maximum parsimony? F 500 The Final Jeopardy Category is: Evolution Please record your wager.
