Evolution Review

All rabbits living in a particular area would be an example of a(n)

• population
• species
• fossil
• individual organism

a measure of how commonly a particular allele occurs in a population is known as the 

• gene pool
• allele frequency
• mutation rate
• phenotype

The more genetic variation  a population has,
 the more likely it is in the same individuals,
will

• evolve
• migrate
• survive
• mutate

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• mutation
• gene flow
• gene pool
• allele

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

What is speciation?

• combining of tow species to form one with different traits
• isolation that affects mating behaviors
• timing of mating that prevents normal sexual selection
• divergence of two or more species from an existing one

An earthquake causes an ocean channel top open and separate an island into two.  the species on each section are now in

• geographic isoliation
• behavioral isolation
• disruptive selection
• temporal isolation

What kid of isolation occurs when two populations of birds have different courtship dances?

• geographic
• sexual
• temporal
• behavioral

two species are in different environments and look very similar.  However, that are not closely related (analogous).  Their resemblance is most likely an example of.

• sexual selection
• temporal isolation
• convergent evolution
• divergent evolution

Other insects can not, but, a bumble bee has just enough weight to open up the snapdragon flower and pollinate.  This adaption is ....

• convergent evolution
• co-evolution
• divergent evolution
