Question 1

1.

What is the term for a feature that allows an organism to survive better in its environment?

variation

vestigial structure

homologous chromosome

adaptation

Question 2

2.

Which of the following statements might best explain the increase in average beak size in the finch population during the drought?

Finches that crack large seeds develop larger beaks over time.

Finches with bigger beaks are better able to crack thick-walled seeds and produce more surviving offspring

Finches with bigger beaks possess more powerful flight muscles and are able to find more food.

Finches with bigger beaks can attack and kill finches with smaller beaks.

Question 3

3.

Which of the following best characterizes natural selection?

Survival and reproduction of the organism that occupies the largest area

Survival of the biggest and strongest organism in a population

Elimination of the smallest organism by the biggest organism

Survival and reproduction of the organisms that are genetically best fit to the environment.

Question 4

4.

Which of the following is NOT a part of Darwin’s theory of evolution by natural selection?

Individuals in a population vary in many ways

Some organisms possess features that enable them to survive better than those lacking the features

Changes in an individual’s genetic material are usually harmful

More offspring are produced than can generally survive

Question 5

5.

A group of imaginary creatures known as “fur babies” come in three forms: super-wooly fur baby, short-haired fur baby, and naked baby. Due to mankind’s inability to control its carbon emissions, a greenhouse effect is created and the global climate rises. Before the global warming, the wooly fur baby existed in the largest frequency with the short-haired fur baby in a close second. The naked baby existed in the lowest numbers. One hundred years later, scientists noticed that not only did the wooly and short-haired fur babies decline to near extinction, but the naked babies’ frequency also increased. Based on this information which is the most likely reason for this trend?

The three organism variations were sexually isolated from each other and thus were not able to produce enough offspring with the adaptation to survive the global warming.

Two of the populations were too furry to survive the global warming while the naked babies had the adaptation to make them best suited for the new environment.

Two of the organism variations lacked the adaptation to survive the global warming while the short-haired fur babies were best suited for the new environment.

Two of the organisms variations lacked the adaptation to survive the global warming and thus no beneficial adaptation was passed on to the offspring.

Question 6

6.

The amino acid sequences of three species shown below were determined in an investigation of evolutionary relationships. Based on these data, which two species are most closely related?

Species A and Species B

Species A and Species C

Species B and Species C

All three are equally related

Question 7

7.

This diagram provides a good example of

vestigial structures

homologous structures

analogous structures

inheritance of acquired traits

Question 8

8.

Which of the following would not qualify as evidence for evolution?

Embryo development begin similarly between fish, chickens, and cats

Whales and Humans containing the same arm bones but serve different purposes

Wings of butterflies, birds, and bats adapted to similar environmental conditions to support flight

Hip bones present in snakes but lacking legs to use them

Question 9

9.

Based on the picture below, what can a scientist conclude?

The cow and rabbit share common ancestry and humans and rabbit do not share common ancestry.

Due to similarities in pharyngeal arches and vertebral column, human and fish share common ancestry.

The fish and human do no share common ancestry due to humans lacking pharyngeal arches while the rabbit and human share common ancestry.

Due to similarities in pharyngeal arches and vertebral column, fish and salamander share common ancestry while rabbit and human do not share common ancestry.

Question 10

10.

Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more modern human jaw we see today. The diagram below shows the skulls of 3 hominid species. Which statement below most closely explains the link between jaw size and hominid evolution?

The jaws of hominids evolved to be larger and more protruding over time.

The jaws of hominids evolved to be smaller and less protruding over time.

There appears to be no change in the jaws of hominids over time.

The jaws of hominids changed over time due to a change in brain size.
