Final Jeopardy

10 points

True or false-A vestigial structure in one organism can be defined as a reduced form of a functional structure

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

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

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)
