The bird beak would be described as a _1_ to the bird making it more successful. _2_ is caused
by examples of bird beaks causing changes over time. What caused the bird beaks to become
different are _3_, which caused more birds to fight for resources known as _4_. As time passed,
this caused birds to live in different habitats causing _5_; or new populations of organisms. The
Galapagos finches are an example of this _6_. As populations change over one trait can be
favored this is known as _7_. Such as the example of human babies being in the 6-8lb range
being more healthy than higher or lower weight this is known as _8_. When the extremes are
more successful and changes the population it is known as _9_. The theory of Evolution is able
to happen through a process which was first written by _10_.
a. Natural Selection
b. Charles Darwin
c. Disruptive Selection
d. Competition
e. Adaptation
ab. Speciation
ac. Stabilizing Selection
ad. Directional Selection
ae. Adaptive Radiation
bc. Mutations
Endosymbiosis and Fossil Quiz
1) The endosymbiotic theory proposes that eukaryotic cells arose from living communities
formed by the merging of prokaryotic organisms and their hosts. Which of the following is the
best evidence to support the endosymbiotic theory?
A. Mitochondria and chloroplasts contain DNA similar to bacterial DNA.
B. Both prokaryotic and eukaryotic organisms require oxygen in order to use energy.
C. Bacteria, mitochondria, and chloroplasts all divide by mitosis, while the cells containing them
divide
by binary fission.
D. Bacteria and mitochondria contain many features that are similar to each other but different
from
those of chloroplasts.
2) The fossil record indicates that some organisms have become extinct. However, some of
these extinct organisms closely resemble organisms that are still alive today. Which of the
following best describes why some extinct species in the fossil record are similar to living
organisms?
A. All organisms have identical genetic codes and therefore produce similar features.
B. Organisms are related by a common ancestor that evolved over a very long period of time.
C. Organisms adapted the same way to their environments in order to produce beneficial traits.
D. Following mass extinctions, new organisms followed the genetic path of the previous extinct
organisms.
3) Fossils usually provide paleontologists with information about each of the following EXCEPT
an organism’s
A. structure.
B. environment.
C. way of life.
D. DNA.
4) Fossils sometimes show that a single species or a small group of species has evolved into
diverse forms that live in different ways. An example of this would be a group of present-day
mammals all having a common ancestor.
Which term describes this phenomenon?
A. adaptive radiation
B. convergent evolution
C. gradualism
D. mutualism
5) Biologists have considered two different explanations to the rate of evolution: gradualism and
punctuated equilibrium. How would the fossil record indicate that an organism had evolved via
punctuated equilibrium?
A. The fossil record would show a slow, steady rate of change from a common ancestor.
B. The fossil record would be incomplete, and numerous holes would exist within the ancestral
record.
C. The fossil record would show rapid change over an extended period of time, with occasional
periods of little change.
D. The fossil record would show little change over long periods of time, followed by a sudden,
brief period of rapid change.

NAME______________
1) _____
2) _____
What do you call this diagram that shows
evolutionary relationships among a group
of organisms?
a. cladogram
b. phylogeny
c. binomial nomenclature
d. dichotomous key
According to the diagram, what organism
would be most closely related to the mouse?
a. hagfish
b. perch
c. lizard
d. pigeon
3 _____Different finch species have beaks of different shapes and sizes. These different beak
structures are evidence of
a. different finch species adapting to different environments over many generations.
b. different finch species with different beak structures coming to the Galápagos Islands
from the mainland.
c. different finch populations being evolutionarily related.
d. individual birds changing their beak characteristics so that they could feed efficiently.
4_______Which is the most likely explanation for the presence of 13 different finch species
on the Galápagos Islands today?
a. Many years ago several different species of birds migrated to the islands and the 13
finch species that currently live there are the only species that survived.
b. Many years ago a small population of a single bird species migrated to the islands and
evolved into the 13 species that live on the islands today.
c. Each of the 13 species has migrated to the islands at different times over the years.
d. A single bird species migrated to one island at around the time of Charles Darwin’s
voyage to the Galápagos and then migrated to all 13 islands.
5______Which statement or statements describes geographically isolated populations? (Read the
five statements below and then select the appropriate answer, a–d.)
i. The two populations live on different islands. ii. One population breeds in late spring and the
other population breeds in late summer. iii. One population eats mostly small, soft seeds and the
other population eats mostly large, hard seeds. iv. The males of one population have different
mating calls than the males of the other population. v. The females of the two populations look
the same.
a. statement i only
b. statements i and iv only
c. statements ii, iii, and v only
d. statement iv only
