Evolution Jeopardy DarwinMicroevolutionMacroevolutionEvolutionary History Potpourri

He suggested the theory of evolution by acquired characteristics Who is Jean Baptiste Lamarck?

Darwin suggested traits should become common if they help in either of these two things What are survival and reproduction

These are 3 necessities in a population for natural selection to occur 1.Diversity 2.Competition 3.Passage of traits 4.Differential survival/reproduction

Explain 4 sources evidence for evolution 1.DNA analysis 2.Protein analysis 3.Transitional fossils 4.Fossil dating 5.Homologous structures 6.Vestigial structures

This was the name of the ship Darwin sailed to the Galapagos on What is the HMS Beagle

Microevolution is the change in the gene pool of this level of structure What is a population?

All new traits arise through this process What are mutations?

These are the 3 major patterns of microevolution (must define each) 1.Directional – shift to one extreme 2.Stabilizing – shift to the middle 3.Diversifying – shift to both extremes

These are the 5 causes of microevolution (define each) 1.Natural selection 2.Sexual selection 3.Mutation 4.Genetic drift 5.Gene flow

How many fewer dominant alleles are present in generation 20 than in generation 0? 17, *20,000 – 0.2*2,000 18, = 17,600

This is how most speciation occurs What is populations become separated and adapt differently until they can no longer mate

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!)

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 reproduction 2.Location of reproduction 3.Reproduction behavior (mating dances, songs etc.) 4.Reproductive anatomies 5.Sperm/egg compatibility 6.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 billion years

This is approximately how long Homo sapiens have existed for What is 200,000 years

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

Use the table below, which shows number of amino acid differences in a common protein, to construct a phylogenetic tree ButterflyJellyfishIguanaSpongeCoralSpider Sea star ButterflyX JellyfishXX IguanaXXX24159 SpongeXXXX24 CoralXXXXX15 Sp J B Se I C Sp

These are 5 species of human relatives/ancestors (or genuses for relatives not in our own genus) Homo sapiens idaltu, Homo neanderthalensis, Homo erectus, Homo habilis, Homo floresesiensis, Homo antecessor, Homo heidelbergensis, Australopithecus, Ardipithecus, Sahelenthrapus, Orrorin

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

This is how geologists estimate the age of rocks and fossils Measuring the amount of a radioactive compound present. (really the ratio of the compound to what it decays into)

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

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 D K P C O F G S
