Ch12&14 Quiz - Evolution and Taxonomy for CK12

_____ is a change in species over a vast amount of time due to random genetic mutations becoming adaptations increasing an organism's fitness.

_____ is organizing organisms into groups according to similarities and differences.

_____ _____ is the vehicle that makes evolution possible.

_____ are positive mutations that increase an organisms chances of living long enough to breed and pass on those advantages to the next generation.

Which of the following statements are true of biogeography?

• Separation of species on different land masses led to the formation of new species.

• Continental drift resulted in plate tectonics.

• Living things cluster where they originate.

• Latitude has an effect on plant and animal distribution.

• Living things move to where they have the most available resources.

Which of the following statements are true of Coevolution?

• Is breeding to enhance a desired trait.

• Is represented by the moth developing a longer probiscus in response to the flower developing a longer nectar tube.

• Is done independently of a relationship with another organism

• Is the relationship we need to have with nature rather than trying to control nature.

• Is when 2 organisms have a relationship where changes in one result in changes in the other over time.

Which of the following statements are true regarding artificial selection?

• Is also called selective breeding.

• It increases genetic variation.

• Humans are choosing the traits to enhance regardless of whether it improves fitness of an organism.

• Is when 2 organisms have a relationship and 1 changes causing change in the other.

• Nature is controlling which traits improve fitness.

Which of the following statements are true about Evolution?

• Happens by means of Natural Selection

• Is a change in organisms over a long period of time due to random genetic mutations creating adaptations.

• Happens by means of artificial selection.

• Shows that we need to control all aspects of nature.

• Shows a relationship between all life on Earth by using the same DNA structure.

Which of the following statements are true about classification?

• It is based on structural similarity.

• It was started by Darwin.

• Each classification group is called a Taxon.

• From most inclusive to least inclusive it will read species, genus, family, order, class, phylum, kingdom, domain.

• From most inclusive to least inclusive it will read domain, kingdom, phylum, class, order, family, genus, species.

Which of the following statements are true of Darwin, Malthus, Lyell, Lamark, and Linnaeus?

• Malthus helped Darwin understand that more offspring are born than nature can support.

• Lamark helped Darwin form the idea that organisms could change over vast amounts of time.

• Lyell helped Darwin understand that earth was much older than scientists of that time thought.

• Linnaeus gave us a classification system that is based on Binomial Nomenclature.

• Darwin gave us the idea that organisms change over time by random mutations causing adaptations.
