2
A paleontologist is most likely to study
3
fossils
4
Which organism above lived most recently?



5
The fish
6
True or FalseExtinct organisms may be related to
other extinct organisms and living organisms.
7
True
8
To determine the time-span during which this
species of fish lived, you should compare this
column to



9
Columns from other parts of the world
10
Name three main reasons that could cause the
extinction of a species
11
Change of environment, loss of food source,
disease
12
Variation is the result of
13
Randomly occuring mutations
14
A trade off for bringing an extinct species
back to life is
15
The species may not survive in the modern world
16
The fact that brown moths are easier seen, and
are less likely to survive in a forest is an
example of
17
Natural selection
18
Green moths survive better than brown moths in
the forest because
19
Their coloring makes them better adapted.
20
Characteristics that are ________ during ones
lifetime cannot be passed on to offspring.
21
acquired
22
According to geological evidence, the earths age
is
23
Billions of years old
24
True or FalseHumans live in the Mesozoic time
period.
25
False, the Cenozoic
26
Which organisms have existed on earth the longest
period of time?
27
Single-celled organisms
28
List mammals, bacteria, and fish from oldest to
youngest appearance on earth.
29
Bacteria, fish, mammals
30
Geologic time periods are divided by
31
The appearance and disappearance of life forms
32
Choose the three scientists who contributed to
evolutionary theory.Darwin, Wallace, Newton,
Lamarck, Einstein
33
Darwin, Wallace, Lamarck
34
Name the islands Charles Darwin studied in
developing his evolutionary theories.
35
Galapagos
36
True or FalseOrganisms have evolved over the
lastfew hundred years
37
False
38
The evolution of _______ on earth has been
affected by humans
39
organisms
40
Name three types of evidence scientists use to
show the relationship between past and present
species.
41
Fossils, skeletons, DNA
42
Mutation happens at which part of an organisms
development?
43
Reproduction
44
True or FalseMutations are always harmful,
never helpful.
45
False sometimes helpful, sometimes harmful,
sometimes neither
46
Explain how genetic mutations happen.
47
The DNA code sequence is miscopied.
48
Which is evidence of genetic variation A black
furred dog born to a brown furred dog or a long
eared puppy born to a dog who has had its ears
clipped?
49
A black furred dog born to a brown furred dog
50
Which describes an example of mutationbig eyed
fish having big eyed offspring, green worms
having green offspring, or striped fish having
spotted offspring?
51
striped fish having spotted offspring
