descendants of the target
pests were immune to the
usual sized dose. Why?
C3 $100

When checking shell color for a species of snail
found only in a remote area seldom visited by
humans, scientists discovered the distribution

The flying squirrel of North America closely resembles
the flying phalanger of Australia. They are similar in size
and have long, bushy tails and skin folds that allow them
to glide through the air. The squirrel is a placental
mammal (carries its young internally), while the
phalanger is a marsupial (has a pouch). These close
resemblances, even though genetically and
geographically separated by great distances, can best
be explained by _____.
a. convergent evolution c.spontaneous generation
b. divergent evolution
d.vestigial structures
C3 $400
Convergent evolution
(things look the same
because of environmental
pressures, but aren’t
closely related)
C3 $500

be defined as ____
C3 $500
“Survival of the fittest”
C4 $100

reduced in function on a
living organism but may
have been used by a
known ancestor is a

C4 $300
The concept that evolution
occurs over long periods
of stability that are
interrupted by
geographically brief
periods of change is
_______
C4 $300
Punctuated equilibrium
C4 $400
Hawaiian honeycreepers are a group of birds
with similar body shape and size. However,
they vary greatly in color and beak shape.

adapted to the foods available in its niche.
The evolution from a common ancestor to a
variety of species is an example of _____.
a. divergent evolution
b. vegetative propagation
c. cross-pollination
d.convergent evolution
C4 $400
Divergent evolution
C4 $500
The theory of continental drift hypothesizes that Africa and
South America slowly drifted apart after once being a
single landmass. The monkeys on the two continents,
although similar, show numerous genetic differences.
Which factor is probably the most important in maintaining
these differences?
a. comparative anatomy
b. geographic isolation
c. comparative embryology
d. fossil records
C4 $500
Geographic isolation
