1) Which of the following mechanisms drives microevolution?
A
neither A or B
B
natural selection
C
both A and B
D
mutations
2) In order for natural selection to occur, what condition must be met?
A
equal distribution of alleles that contribute to the best opportunity for mating
B
natural event, such as a fire or flood, causes a change to the environment
C
genetic variation causing a differential in survival and reproduction rates
D
homologous structures among all the individuals in a population
3) Bird beaks show a variety of characteristics based on the bird’s specific niche. Which beak most likely belongs to a bird that strains its food from mud and water?
A
hooked beak like a hawk
B
long, narrow, pointy beak like a egret or blue heron
C
rounded bill like a duck
D
short, pointed beak like a cardinal
4) What is macroevolution?
A
speciation that occurs when populations become isolated due to geographical changes
B
major evolutionary transitions from one type of organism to another occurring at or above the species level
C
changes in population genetics in which intermediate forms of a trait are favored
D
changes in gene frequency within populations or species
5) Scientists believe that humans evolved from early ancestors that were similar to apes. This idea is categorized as
A
Hardy-Weinberg equilibrium
B
change in allele frequency
C
macroevolution
D
microevolution
6) What is one way to know that speciation has occurred?
A
The two populations cannot reproduce.
B
The two populations have experienced genetic drift.
C
There is an increase in genetic mutations.
D
There is a decrease in allele frequency.
7) How have scientists used biogeography to prove that Earth's continents were once a single land mass?
A
They have found fossils of organisms that share a common ancestor on different continents.
B
They have found organisms that share a common ancestor on the same continent.
C
They have matched the DNA from a species on one continent to a species on a different continent.
D
They have found different fossils on all of the continents.
8) Different birds have feet that are adapted for different uses. Which bird foot most likely belongs to a bird that uses its feet to capture rodents and other animals as prey?
A
Feet and claws that look like a chicken's
B
webbed feet like a duck
C
narrow feet with narrow toes like a robin's
D
feet and claws that look like an eagle's
9) The similarities between the embyonic structures of different species can be used as evidence through
A
natural selection
B
the fossil record
C
molecular sequencing
D
comparative morphology
10) Through natural selection, many plants have evolved adaptationsWhat is the likely outcome of these adaptations?
A
Reduced reproduction
B
Decreased survival
C
Increased rates of photosynthesis
D
Protection from predators
11) A rancher wants to investigate the use of artificial selection in his cattle herd. Which of these options is an example of artificial selection?
A
Choose one individual in a population of sheep to favor with food and shelter and see if it mates more.
B
Trace the family tree of a chicken that lays many eggs back through several generations.
C
Breed a cow that produces large quantities of milk with a bull that comes from a line of cattle with long lifespans.
D
Separate a population of rabbits and monitor any trait changes over the next few generations.

two weeks
B
five years
C
a few months
D
nearly 20 years

all organisms descended from a common ancient species
C
it is more common to find fossils that are related to each other
D
all organisms are related through their DNA
