Darwin suggested traits should become common if they help in either of these two things
What are survival and reproduction
![Page 4: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/4.jpg)
These are 3 necessities in a population for natural selection to occur
1. Diversity2. Competition3. Passage of traits4. Differential survival/reproduction
![Page 5: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/5.jpg)
Explain 4 sources evidence for evolution
1. DNA analysis2. Protein analysis3. Transitional fossils4. Fossil dating5. Homologous structures6. Vestigial structures

This was the name of the ship Darwin sailed to the Galapagos on
What is the HMS Beagle
![Page 7: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/7.jpg)
Microevolution is the change in the gene pool of this level of structure
What is a population?
![Page 8: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/8.jpg)
All new traits arise through this process
What are mutations?
![Page 9: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/9.jpg)
These are the 3 major patterns of microevolution(must define each)
1. Directional – shift to one extreme
2. Stabilizing – shift to the middle3. Diversifying – shift to both
extremes
![Page 10: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/10.jpg)
These are the 5 causes of microevolution (define each)
1. Natural selection2. Sexual selection3. Mutation4. Genetic drift5. Gene flow
![Page 11: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/11.jpg)
How many fewer dominant alleles are present in generation 20 than in generation 0?
17,6000.9*20,000 – 0.2*2,00018,000-400 = 17,600

This is how most speciation occurs
What is populations become separated and adapt differently until they can no longer mate
![Page 13: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/13.jpg)
This must occur for populations to be considered different species
What is an inability for them to successfully reproduce with each other? (note that they may still mate- just can’t produce fertile offspring!)
![Page 14: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/14.jpg)
The process of _____ produces the structures above, which are called _______
Divergent evolution, homologous structures

These are 5 ways different species can be prevented from combining gene pools with each other
What are:1.Timing of reproduction2.Location of reproduction3.Reproduction behavior (mating dances, songs etc.)4.Reproductive anatomies5.Sperm/egg compatibility6.Fertility of offspring (i.e. mules)7.Viability/survival of offspring

Darwin did not use the term evolution. He called the concept that species come from common ancestors this
What is Descent with Modification

This is the approximate age of the Earth
What is 4.5-4.6 billion years

What is 200,000 years

All members of a phylum must all belong to the same of these
What are Kingdom and Domain.

This pattern is shown above
What is co-evolution

A harmless species evolves to appear similar to a poisonous or toxic species in this process
What is mimicry
![Page 24: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/24.jpg)
This is how geologists estimate the age of rocksand fossils
Measuring the amount of a radioactive compound present. (really the ratio of the compound to what it decays into)
![Page 25: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/25.jpg)
Hagfish and lampreys are sometimes grouped together as Agnathans, or jawless fish. Explain why this is a paraphyletic, or non-ideal taxonomic group
Lampreys are more closely related to jawed fish and all terrestrial vertebrates than to hag fish
![Page 26: Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri 100 200 300 400 500](https://reader035.vdocument.in/reader035/viewer/2022062413/5a4d1b5c7f8b9ab0599ab89e/html5/thumbnails/26.jpg)
This is the full taxonomy of humans (I will allow one mistake or omission) but you must identify which taxonomic group goes with which
Eukarya Animalia Chordata Mammalia Primate Hominidae Homo Sapiens
