1
Charles Darwin suggested what four processes combine to promote natural selection of organisms?
overpopulation, genetic mutation, prevention and adaption
evolution, overproduction, genetic selection and extinction
overproduction, adaption, artificial selection & extinction
overproduction, genetic variation, selection and adaption
2
The shorter, rounder beaks that Darwin observed belonged to finches that used their beaks to
pick large berries from a branch
grab and swallow insects
cut through the outside of a plant to eat the soft tissue
crush open seeds to eat the inside
3
This economist warned that soon populations will grow faster than the food production required.
Charles Darwin
Thomas Malthus
Jean Baptiste Lamarck
Charles Lyell
4
Within species there are natural differences in inherited characteristics. This is called
evolution
extinction
variation
adaption
5
What process is when traits within a population change over generations to produce new species?
evolution
adaption
variation
extinction
6
Darwin suggested animals that inherit advantageous traits reproduce more successfully. This is
extinction
natural selection
variation
artificial selection
7
Charles Darwin recorded a diary of observations from his five-year voyage, published in 1839 as
The Voyage of the Beagle
20,000 Leagues under the Sea
On the Origin of Species
The Finches of Galápagos
8
Charles Darwin sailed around the world on the HMS Beagle. On the ship, his job was
the captain
a naturalist
the helmsman
a whaler
9
Using the number of amino acid differences in cytochrome
c
, which animals here are most alike?
horse and donkey
chicken and penguin
snake and horse
moose and squirrel
10
Fossils that show the relation between two similar organisms are called
transitional fossils
unused structures
extinction events
vestigial fossils
11
In addition to the fossil record, biologists find evidence for evolution in all of these EXCEPT
developmental similarities in growing embryos
the movement of organisms to more hospitable environments
shared structural traits among related organisms
genetic information stored in the DNA of various organisms
12
Even though the island birds were all finches, Charles Darwin noticed the different beak shapes
had no affect on how the different finches survived
were the best way to tell young finches from mature birds
were suited to gathering and eating different food
allowed the finches to make different sounds
13
This geologist theorized that Earth today is the result of small changes over millions of years
Charles Darwin
Thomas Malthus
Charles Lyell
Jean Baptiste Lamarck
14
Charles Darwin collected birds with different features from across the Galápagos Islands and
discovered that the larger ones no longer knew how to fly
learned they all ate exactly the same foods from the islands
later realized they were variations of birds called finches
found the birds to share no similarities other than feathers
15
What evidence found by scientists supports the theory of evolution?
fossil evidence and molecular evidence
fossil gaps and molecular evidence
fossil evidence and extinct species
fossil evidence and the fossil record
16
Rock layers preserve evidence of ancient organisms. These imprints or remains are called
amber
petrified rock
fossils
dinosaurs
17
Whales produce milk, breathe air and give birth to live offspring. This evidence suggests that
whales evolved from fish
whales evolved from sharks
whales evolved from swimming dinosaurs
whales evolved from mammals living on dry land
18
Charles Darwin noticed that finches with longer, narrower beaks were best suited to
crush open seeds to eat the inside
grab and swallow insects
pick large berries from a branch
cut through the outside of a plant to eat the soft tissue
19
Based on differences in cytochrome
c
, which animals are more similar than penguins and donkeys?
snake and penguin
horse and penguin
horse and chicken
snake and donkey
20
The information provided by preserved, sequential evidence of once living organisms is called
absolute dating
sedimentary plates
relative dating
the fossil record
21
This total loss of a species can be caused by competition, new predators or a change in habitat
extinction
evolution
adaption
variation
22
The vestigial leg bones found in whales are
an unused structure
an example of variation
slowly turning into functional legs
not made of bones at all
23
According to this model of proposed common ancestors, which animals are most closely related?
pig and hippo
camel and deer
cow and pig
hippo and whale
24
The vegetarian finch has a wide, curved beak that lets the bird easily
pick large berries from a branch
crush open seeds to eat the inside
cut through the outside of a plant to eat the soft tissue
grabs and swallow insects
25
The fossil record
provides no information since tectonic plates move too much
has gaps in time where no fossils have been discovered
gives a complete picture of life on Earth from the beginning
shows how entire species went extinct millions of years ago
26
The process by which humans select plants or animals for breeding based on desired traits is
extinction
artificial selection
variation
natural selection
27
Adaption of traits to help an organism survive, feed and reproduce depend on
only environmental factors
both environmental factors and the needs of the species
only the needs of the species
neither environmental factors nor the needs of the species
28
The HMS Beagle sailed around the globe to examine unusual animals in all these regions EXCEPT
the Galápagos Islands
the Florida Peninsula
Australia
the Andes Mountains
29
The cactus finch has a narrow, pointed beak that lets the bird easily
crush open seeds to eat the inside
cut through the outside of a plant to eat the soft tissue
pick large berries from a branch
grab and swallow insects
30
Based on amino acid differences in cytochrome
c
, which animals listed here are most different?
snake and horse
horse and donkey
moose and squirrel
chicken and penguin
31
An inherited trait that helps an organism survive and reproduce in its environment is called
an adaption
evolution
a variation
extinction
32
When a plant or animal has more offspring than the environment can support, this is called
adaption
overpopulation
overproduction
extinction
33
This scientist suggested that organisms acquire traits and pass them onto their offspring.
Thomas Malthus
Charles Lyell
Charles Darwin
Jean Baptiste Lamarck
34
An inherited characteristic, like the thick fur or long legs of different dog breeds, is called
a mutation
a trait
a bonus
an advantage
