10 points True or false. A vestigial structure in one organism can be defined as a reduced form of a functional structure
10 points True, vestigial structures are reduced forms of a functional structure –our appendix and a snake’s pelvis are examples
20 points True or False. Biochemical traits helped Darwin unravel his theory of evolution
20 points False, biochemical traits were not yet known when Darwin made his observations
30 points True or false – Darwin developed his theory of evolution exclusively from his work on the Galapagos Islands
30 points False, Darwin spent only a short time at the Galapagos, but then lived back in England for over 20 years before he released his observational findings
40 points True or false - Homologous structures indicate a shared ancestry, while vestigial structures do not
40 points False, both homologous and vestigial structures show a shared ancestry
50 points True or false. Fossils provide evidence of evolution
50 points True, fossils provide scientists with great evidence of past life forms and changes over time in species (evolution)
10 points Charles Darwin was a naturalist on this ship – give complete name
10 points Charles Darwin was a naturalist on the HMS Beagle
20 points Pollinators and flowering plants – moth and a comet orchid – are examples of ______.
20 points Pollinators and flowering plants – moth and a comet orchid – are examples of coevolution
30 points Modified True or false: Punctuated Equilibrium and Gradualism are two models that describe the cause of speciation.
30 points False, Both describe the RATE of speciation, not the cause
40 points Modified true/false Inbreeding in a population leads to individuals that are heterozygous for many traits
40 points False, inbreeding leads to more homozygous traits in individuals
50 points Modified True/False The Hardy-Weinberg Principle says that evolution will not occur in a population unless allelic frequencies are acted on by forces that cause change
50 points True, the Hardy-Weinberg principle says that evolution will not occur in a population unless allelic frequencies are on by forces that cause change.
10 points In terms of population size (large or small) and amount of mutations (few or many) Which combination would provide the greatest potential for evolution?
10 points Having a small population with many mutations will provide the greatest potential for evolutionary change.
20 points Bird wings and insect wings are examples of _______ structures Bonus 10 points: do they have a common ancestor, yes or no?
20 points Bird wings and insect wings are examples of Analogous structures Bonus 10 points: do they have a common ancestor, yes or no? NO common ancestor
30 points Snake pelvis and human appendix are examples of _____ structure
30 points Snake pelvis and human appendix are examples of vestigial structure
40 points Bones of the bird wing, whale pectoral fin and reptile forelegs are examples of _____ structures Bonus 10 points: Do they show a common ancestor- Yes or no?
40 points Bones of the bird wing, whale pectoral fin and reptile forelegs are examples of homologous structures Bonus 10 points: Do they show a common ancestor- Yes
50 points Superficially similar features molded by natural selection in very different species would be classified as _____ structures. “Superficial” means that it only appears to be the same from the outside, but is totally different on the inside
50 points Superficially similar features molded by natural selection in very different species would be classified as Analagous structures. “Superficial” means that it only appears to be the same from the outside, but is totally different on the inside
10 points If Derived traits are recent, then _____ traits are more primitive
10 points If derived traits are more recent, then ANCESTORAL traits are more primitive
20 points If a population of organisms is in genetic equilibrium, then the _______ principle is expressed.
20 points If a population of organisms is in genetic equilibrium, then the HARDY -WEINBERG PRINCIPLE is expressed.
30 points In general, if a population diverges and becomes reproductively isolated, then _____ has occurred.
30 points In general, if a population diverges and becomes reproductively isolated, then SPECIATION has occurred
40 points If no physical barrier separates a diverging population as it becomes two distinct populations, then _____ has occurred.
40 points If no physical barrier separates a diverging population as it becomes two distinct populations, then Sympatric speciation has occurred. 30 Bonus points: NAME the other type of speciation and give an example…
50 points If a species is suddenly introduced into a new habitat (Example: the cichlids that once lived in Africa’s Lake Victoria) then _____ might occur.
50 points If a species is suddenly introduced into a new habitat (example: the cichlids that once lived in Africa’s Lake Victoria) then Adaptive Radiation might occur.
10 points Modified True/False: A mutation is a random change in genetic material
10 points TRUE, A mutation is a random change in genetic material
20 points Modified True/False Any change in the allelic frequencies in a population that is due to chance is called founder effect.
20 points FALSE Any change in the allelic frequencies in a population that is due to chance is called Genetic drift
30 points Modified True/False A population of ants declines to a very low number. When the ants’ habitat is turned into a park for picnics by humans, the population of ants rebounds. This is an example of natural selection.
30 points False A population of ants declines to a very low number. When the ants’ habitat is turned into a park for picnics by humans, the population of ants rebounds. This is an example of bottleneck
40 points Modified True/False Humans either born below-normal or abovenormal birth weights have a lower chance of survival than those with average birth weights. Thus, human birth weights vary little. This is a form of natural selection called stabilizing selection.
40 points true, Humans either born below-normal or above-normal birth weights have a lower chance of survival than those with average birth weights. Thus, human birth weights vary little. This is a form of natural selection called stabilizing selection.
50 points Modified True/False Embryos of different organisms exhibit homologous structures during early development, but later become totally different structures in adult form. This indicates that the organisms evolved from different ancestors.
50 points False Embryos of different organisms exhibit homologous structures during early development, but later become totally different structures in adult form. This indicates that the organisms evolved from common ancestors.
Final Jeopardy Name the 5 different mechanisms of evolution
Final Jeopardy Answer Mechanisms of evolution include: genetic drift (founder effect, bottleneck), gene flow, nonrandom mating, mutations, and natural selection (which would include: stabilizing selection, disruptive selection, and directional selection)
