Final Jeopardy
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/falseInbreeding 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/FalseThe 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 pointsBird 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 pointsBones 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 pointsSuperficially 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 pointsIf 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 pointsIf 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 pointsModified 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 pointsFalseA 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 pointsModified 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 pointstrue, 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 pointsModified 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 pointsFalseEmbryos 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)
