Biology 152 Exam 1 Practice Questions and
answer 100% correct
D Which of the following facts provides the
clearest evidence for common ancestry
over single ancestry?
A. 100 Ma fossil have been found whose
leaves are almost indistinguishable from
living redwoods
B.Rodents are found on all continents
C. Birds have very light, air-filled bones
that allow them to fly
D.Whales have bones embedded in the
muscles near their tail which develop
similarly to the pelvis (hip bone), but these
bones do not support limbs
,A Which of these biogeographic patterns
provide the weakest evidence for common
ancestry?
A. The giant panda is only found in the
bamboo forests of China
B.All the monkeys in South America have
prehensile tails, monkeys in the rest of the
world do not
C. Front-fanged snake species are found
throughout Africa but the snakes in
Madagascar are not front-fanged
D.All 115 species of lobeliad found in Hawaii
have similar traits to one another than to
plants from other landmasses
C Which is a case of evolution?
A. A child growing up in a hot environment
produces a higher density of sweat glands
than a child in cold conditions
B.Increased use of air-conditioners in rich
countries reduces the average density of
sweat glands
C. US residents whose ancestors came
from cold climates tend to produce fewer
sweat glands than residents descended
from warmer climate populations
