Change in the frequency of alleles in a gene pool Final Jeopardy Evolution Change in the frequency of alleles in a gene pool Final Jeopardy

Inheritance of acquired characteristics $200 Inheritance of acquired characteristics Lamarck belief that you could develop traits in your lifetime & pass these along to your offspring Single Jeopardy – Category 1

Darwin belief that those best suited to the environment would live. $400 Survival of the fittest Darwin belief that those best suited to the environment would live. Single Jeopardy – Category 1

$600 Use & Disuse Lamarck’s belief that useless body structures would disappear & useful ones would develop Single Jeopardy – Category 1

Kettlewell’s study of the peppered moth is often used as an example $800 Natural selection Kettlewell’s study of the peppered moth is often used as an example Single Jeopardy – Category 1

Darwin’s influences $1000 Earth changes (Hutton) Catastrophes occur (Cuvier) Earth is older than previously thought (Lyell) Competition (Malthus) British farmers (Artificial selection) Single Jeopardy – Category 1 Darwin’s influences

Evidence of evolution that gives us a time scale? $200 Fossil Records Evidence of evolution that gives us a time scale? Single Jeopardy – Category 2

What provides evidence of evolution? $400 Fossils Embryology Homologous structures Vestigial Structures Biochemical evidence Single Jeopardy – Category 2 What provides evidence of evolution?

What is an example of a vestigial structure in humans? $600 Appendix Wisdom Teeth Ear wiggling muscles What is an example of a vestigial structure in humans? Single Jeopardy – Category 2

How is embryology evidence of evolution? $800 Embryos of different organisms are the same at early stages of development. This suggest they have come from a common ancestor How is embryology evidence of evolution? Single Jeopardy – Category 2

Explain the biochemical evidence of evolution? $1000 Similar RNA/DNA Same amino acids More similar proteins in closely related species Explain the biochemical evidence of evolution? Single Jeopardy – Category 2

Why are homologous structures used as evidence of evolution? $200 Homologous structures show that organisms have a recent common ancestor Why are homologous structures used as evidence of evolution? Single Jeopardy – Category 3

What is a vestigial structure? $400 They are structures that no longer appear have a function so must have been present in an earlier common ancestor. Single Jeopardy – Category 3 What is a vestigial structure?

What are homologous Structures? Examples? $600 Body parts that have a similar structure but have different functions Examples: forearm of a cat & fin of a whale What are homologous Structures? Examples? Single Jeopardy – Category 3

What are analogous Structures? Example? $800 Body parts that have different structures but the same function Example: dolphin & fish fins What are analogous Structures? Example? Single Jeopardy – Category 3

Why do some vestigial structures still exist? $1000 It takes time for evolution to occur. It requires people to be born without the structure and mate with others born with out the structure Why do some vestigial structures still exist? Single Jeopardy – Category 3

What are two models of evolution? $200 Gradualism and Punctuated Equilibrium What are two models of evolution? Single Jeopardy – Category 4

Which model did Darwin propose? $400 gradualism Which model did Darwin propose? Single Jeopardy – Category 4

Explain Punctuated Equilibrium $600 A species is in a stable state (little/no changes) for an extended period of time followed by a brief and rapid period of change that produces a new species Explain Punctuated Equilibrium Single Jeopardy – Category 4

It is a model of evolution that is based on slow and steady changes $800 It is a model of evolution that is based on slow and steady changes Single Jeopardy – Category 4 What is gradualism?

Why did the punctuated equilibrium model develop? $1000 To explain gaps in some of the fossil records; suggests that there are no gaps but rather these were periods of rapid change. Single Jeopardy – Category 4 Why did the punctuated equilibrium model develop?

What is the shape of DNA? $200 A Double Helix Single Jeopardy – Category 5

What are the four nitrogenous bases of DNA? $400 1) Adenine 2) Thymine 3) Cytosine 4) Guanine What are the four nitrogenous bases of DNA? Single Jeopardy – Category 5

What base pairs with Guanine? $600 Cytosine What base pairs with Guanine? Single Jeopardy – Category 5

What are the three parts of a DNA nucleotide? $800 A phosphate group, a 5 carbon sugar (deoxyribose), a nitrogenous base Single Jeopardy – Category 5 What are the three parts of a DNA nucleotide?

Why does DNA play an important role in evolution? $1000 Mutations that occur during replication cause the variations that evolution can act upon Why does DNA play an important role in evolution? Single Jeopardy – Category 5

$200 A group of organisms who are capable of producing viable (fertile) offspring. What is a species? Single Jeopardy – Category 6

What is convergent evolution? $400 when different organisms that live in similar environments develop similar characteristics Example: birds, insects, flying mammals, pterodactyl Single Jeopardy – Category 6 What is convergent evolution?

What is divergent evolution? What is another name for it? $600 It is when one species gives rise to many different species Adaptive Radiation What is divergent evolution? What is another name for it? Single Jeopardy – Category 6

What is reproductive isolation? $800 The inability of a species to breed successfully due to geographical, behavioural, physiological or genetic barriers What is reproductive isolation? Single Jeopardy – Category 6

What are the steps of speciation? $1000 One species (ancestors), separation of populations (often geographic isolation), changes in the gene pool (divergent evolution), reproductive isolation, two species Single Jeopardy – Category 6 What are the steps of speciation?
