Answers
1
A farmer's use of the best livestock for breeding is an example of
extinction
natural selection
adaptations
artificial selection
2
What is an acquired trait?
a characteristic you can pass on to your offspring
physical fitness, for example
a characteristic you can develop in your own lifetime
a characteristic you inherited
3
A bat wing, a cat leg, a whale fine, and a human arm are examples of...
homologous structures
analogous structures
adaptive radiation
convergent evolution
4
Analogous structures...
look similar and have the same function but differ in origin
have the same structure and development on the inside
have no evolutionary relationship
look similar and have the same function and origin
5
Which of the following is NOT evidence for evolution?
textbook facts
anatomical record
fossil record
molecular record
6
Fossils tell a story that ....
life is old
life has changed
the earth is old
evolution is a new phenomenon
7
Who is considered the father of evolutionary theory?
Gregor Mendel
Mr. Gomez
Charles Darwin
Galapagos
8
We can see evidence for evolution in a modern day, visible process called,..
DNA record
fossil record
artificial selection
selective breeding
9
In the process of natural selection, what is nature "selecting"?
those with the best traits for surviving that place and time
the sneakiest, most camouflaged organisms
the luckiest organisms
the strongest, fastest, toughest organisms
10
Creatures have changed over time. How do we know this?
the movies tell us so
fossil record
everything changes over time
Galapagos organisms are different from those in S. America
11
Comparing DNA & protein structures is what kind of evidence for evolution?
artificial selection
molecular
fossil
anatomical
12
Which came first, land mammals or sea mammals?
sea
neither, they evolved from birds in the air
land
amphibians
13
Which of the following does NOT provide evidence for evolution?
homologous structures of living things
function of structures in an individual organisms
fossil record
geographical distribution of living things
14
A dragonfly wing, a bird wing and a bat wing are examples of...
convergent evolution
homologous structures
analogous structures
common ancestry
15
What did Darwin mean by "descent with modification"?
small changes occur between generations
organisms descend from parents, but are modified in some way
to easily go down a hill, we have to modify our approach
nature modifies organisms before next generation
16
Same bones with different functions is an example of which kind of evidence for evolution?
fossil record
anatomical
molecular
artificial selection
17
How well an organisms survives and reproduces in its environment is its
common descent
fitness
analogies
homologies
18
What was the name of the book that Darwin published outlining his theory of evolution?
"Hell on earth"
"Galapagos or bust"
"Origin of Species"
"Descent with modification"
19
Which organisms survive and reproduce?
those that are lucky
the strongest and fastest
those with the "fittest" traits for that environment & time
those that nature "selects"
20
The process that drives evolution, where the fittest traits are "chosen " to survive
evolution
natural selection
biodiversity
adaptation
21
DNA and RNA provide evidence of evolution because
no two organisms have exactly the same DNA
each RNA codon specifies just one amino acid
in most organisms, the same codons specify same amino acids
all organisms have nearly identical DNA / RNA
22
When are two organisms considered the same species?
they can mate and produce fertile offspring
they look and act alike
they have the same common ancestor
their DNA are similar
23
What is the difference between an acquired trait and a genetic trait?
acquired traits can become genetic
acquired traits - can be developed, genetic traits - can't
genetic traits - determined by genes, acquired traits -not
they are the same
24
What findings explain the genetic difference in human and chimps?
apes carry a split chromosome increasing their total # to 48
we have very different common ancestors
2 human chromosomes fused together to reduce total # to 46
chimps have 48, humans 46
25
What is a vestigial structure?
leg bones on a whale, for example
a structure acquired during an organisms lifetime
remnants of a structure that was once used but now is not
fingers on a human hand, for example
26
The birds that Darwin found on the Galapagos islands differed greatly in their...
intelligence & tool use
beaks
nesting behavior
feather coloration
27
What kind of bird did Darwin find on the Galapagos islands in 14 different species?
sparrows
finches
warblings
woodpeckers
28
Which is NOT an observation that we have to support evolution
changes in organisms have been big, quick changes
different species lived in the past
there have been changes in living organisms over time
there are many different creatures on earth
29
All of the following are evolutionary changes that we can witness in a short time except...
insects becoming resistant to pesticides
the increase in intelligence of people
bacteria becoming resistant to antibiotics
flu viruses that mutate from one year to the next
30
Fish fins and dolphin fins are examples of...
convergent evolution
analogous structures
common ancestry
homologous structures
31
Same structures that come from the same origin are called...
homologous
analogous
convergent
coincidence
32
Changes in living organisms /populations over time (generations) is called...
biodiversity
evolution
natural selection
adaptation
33
The fossil record shows that birds evolved from ancestral species of....
fish
amphibians
reptiles
mammals
34
The earth is very old. How do we know this?
radioactive dating of the rocks
the movies tell us so
testing and observation
the bible tells us so
35
A diagram showing closely related species from a common ancestor is called...
selective breeding
a molecular record
a family tree
binomial nomenclature
36
An inherited trait that increases an organism's ability to survive & reproduce
evolution
natural selection
adaptation
biodiversity
37
We can see evolution happening quickly during...
antibiotic resistance
pesticide resistance
a human lifetime
examination of the fossil record
38
which explains both the unity of life and the diversity of life...
evolution
findings on the Galapagos
