a)
The common ancestor of the lizards first colonized the island of El Hierro.
b)
The ancestors of each species came from different continents at different times.
c)
The common ancestor of the lizards probably came from Africa.
d)
The ancestors of each species evolved in Spain and were brought to the islands at the same time.
3.
a)
belong to the same species
b)
must range great distances to eat
c)
have very similar skeletal structures
d)
are descended from a common ancestor
4.
Genome maps provide the DNA sequences of chromosomes. Some scientists have compared the genome maps of a hedgehog and a sloth. What do these genome maps allow the scientists to determine?
a)
The color patterns of the offspring of each species
b)
How much the size ranges of the two species differ
c)
The methods of protein synthesis that each species uses
d)
How closely related the two species are to each other
5.
a)
1 and 2
b)
3 and 4
c)
5 and 6
d)
7 and 8
6.
a)
have the same basic structure
b)

7.
In the European roe deer, implantation of embryos after breeding is delayed. The deer breed in July or August but do not give birth until the following May or June. From summer to late December, the embryo sends a signal that causes the female to release hormones, allowing the embryo to continue to develop normally. Why is delayed implantation an advantageous adaptation for the European roe deer?
a)
Delayed implantation allows the mother to continue to breed with other males.
b)
Without delayed implantation, the females would not be able to carry a pregnancy to full-term.
c)
Delayed implantation enables the female to give birth to more fawns each year.
d)
Without delayed implantation, the fawns would be born in the winter when food is scarce and the weather is harsh.
8.
Scientists estimate that there are more than 20,000 species of ants. The species range in size from 1 mm long to 38 mm long and live in most environments. The diets of ants range from flowers and seeds to fluids from their own larvae. Ants have been able to successfully inhabit so many different environments because their populations have been able to -
a)
hybridize with other species of insects
b)
adapt to a variety of habitats and food sources
c)
fill niches usually occupied by mammals
d)
occupy habitats that have no other life-forms
9.
In Madagascar scientists have discovered a moth, Xanthopan moganii praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin's orchid. The orchid has a nectar-producing tube that is 27.9 cm. long. How is the moth's proboscis size an adaptation for its environment?
a)
The moth can avoid longer animals.
b)
The moth can pollinate other flowers.
c)
The moth has little competition for food.
d)
The moth has time to feed during the day.
10.
a)
make it easier for the scarlet king snake to attract prey
b)
make it easier for the scarlet king snake to interbreed with the other snake
c)
allow the scarlet king snake to blend in with its environment
d)
protect the scarlet king snake from predators
