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 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.

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)
