Evolution Lesson 3

Mechanisms of Evolution

Multiple Choice

Evolution of new species; occurs when members of similar populations no longer interbreed to produce fertile offspring

• gene pool

• speciation

• Populations

• species

Multiple Choice

Organisms that look alike; can interbreed to produce fertile offspring.

• gene pool

• speciation

• Populations

• species

Multiple Choice

Movement of individuals in and out of a population.

• gene pool

• Allelic Frequency

• genetic drift

• gene flow

Multiple Choice

Alterations of alleles by chance events; usually in small isolated populations.

• gene pool

• Allelic Frequency

• genetic drift

• gene flow

Multiple Choice

A population's genes remains the same (not evolving).

• gene pool

• Allelic Frequency

• Populations

• Genetic Equilibrium

Multiple Choice

All the genes in a population.

• gene pool

• Allelic Frequency

• Populations

• Genetic Equilibrium

Multiple Choice

What does the Hardy-Weinberg equilibrium measure?

• changes in allele frequencies

• numbers of mutations

• goodness of fit

• genetic diversity

Multiple Choice

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

• Genetic Drift
• Natural Selection
• Non-random mating
• Mutation

Multiple Choice

What do you call all of the genes in a population?

• Gene pool

• Relative Frequency

• Genetic Drift

• Allele pool

Multiple Select

Which of the following would disrupt Hardy-Weinburg equilibrium? (select all that apply)

• Mutations

• Random mating

• Small population

• Natural selection

Multiple Choice

The American toad (Anaxyrus americanus) and Fowler's toad (Bufo fowleri) live in the same area. However, The American toad mates in early summer while Fowler’s mates in late summer.

• Geographic isolation

• Behavioral isolation

• Temporal isolation

Multiple Choice

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are now mating only with the tail they prefer. What type of reproductive barrier is this?

• behavioral isolation

• hybrid sterility

• temporal isolation

• mechanical isolation

Multiple Choice

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?

• behavioral isolation

• temporal isolation

• gametic isolation

• geographic isolation

Multiple Choice

Populations of organisms change rapidly interrupting long, stable periods without change.

• Gradualism

• Punctuated Equilibrium

• Convergent Evolution

• Co-evolution

Multiple Choice

When species reproduce at different times.

• geographic isolation

• behavioral isolation

• Temporal (Reproductive) Isolation

• species

Multiple Choice

Populations of organisms change gradually over time…slow, steady change.

• Gradualism

• Punctuated Equilibrium

• Convergent Evolution

• Co-evolution

Multiple Choice

Where species that were once similar become different.

• Divergent Evolution

• Adaptive Radiation

• Convergent Evolution

• Co-evolution

Multiple Choice

Rapid, divergent evolution that occurs when a species evolves into an array of species to fit diverse habitats.

• Divergent Evolution

• Adaptive Radiation

• Convergent Evolution

• Co-evolution

Multiple Choice

When distantly related or unrelated organisms evolve similar traits due to similar habitats, causing them to resemble each other.

• Divergent Evolution

• Adaptive Radiation

• Convergent Evolution

• Co-evolution

Multiple Choice

The process by which two species evolve in response to changes in each other over time.

• Divergent Evolution

• Adaptive Radiation

• Convergent Evolution

• Co-evolution
