1.
The scientific theory of evolution is supported by different types of evidence. The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?
a)
It provides information about the organisms' habitats.
b)
It shows possible common ancestry between organisms.
c)
It provides information to determine the organisms' ages.
d)
It shows possible chromosomal similarities between organisms.
2.

homologous structures.
b)
analogous structures.
c)
Hox genes.

Molecular evidence in support of natural selection includes
a)
the nearly universal genetic code.
b)
the presence of vestigial structures.
c)
a tendency toward perfect, unchanging DNA in various species.
d)
the transmission of acquired characteristics by DNA.
4.
Modern sea star larvae resemble some primitive vertebrate larvae. This similarity may suggest that primitive vertebrates

evolved from sea stars.

belong to the same species as sea stars.
d)
none of these

conditions in an organism’s environment ensures the organism’s survival.

b)
The organisms that are the fittest are always largest and strongest.

evolution
13.
In his book On the Origin of the Species, Charles Darwin described how species change over time. Which of the following is NOT part of his observations that describes the mechanisms of natural selection?

Organisms produce more offspring than can survive.
b)
Disease and natural disaster will limit population growth.

available niches
b)
existing predators
c)
chromosome number
d)
available food resources
15.
Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species.

a)
fewer mutations
b)
limited food resources
c)
limited beak variations
d)
overproduction of offspring
16.
Form a Hypothesis Considering the body structure of the tortoises shown in Figure 16–2, which tortoises—a population from Pinta Island or a population from Isabela Island—might survive more successfully on Hood Island? Why?
a)
The Pinta Island tortoises would be likely to survive more successfully because they appear to be more similar to the Hood Island tortoises.
b)
The Isabela island tortoises because their head and neck are more protected.
c)
both of these are correct
d)
neither one of these are correct
17.
