What is Evolution?
The process of a species dying out.
The process of making food for a plant species.
Process of small change in a species over a long time period
The process of obtaining nutrients.
2
The beak shape makes it easy for each bird to obtain food in a different way. These are
examples of competition
examples of dynamic equilibrium
examples of biological adaptation
examples of camouflage
3
Dogs & cats have similar body structures but do not mate w/ each other. They are classified in
different kingdoms, but the same species
different kingdoms and different species
the same kingdom, but different species
the same kingdom and the same species
4
What is the previous species called that a new species evolved from?
Selective breeding
Descent with modification
P1 Generation
Common ancestor
5
Naturally occurring variations within a species are mainly the result of mutations and
dynamic equilibrium
metabolism
camouflage
sexual reproduction
6
Which is the common ancestor for A,B,C, &D?
Ancestor 1
Ancestor 3
Ancestor 2
7
This process produces the greatest number of variations with in a group of organisms.
asexual reproduction
cloning
sexual reproduction
budding
8
What does survival of the fittest mean?
Everything survives.
Nothing survives.
Only the strong survive.
Only the best adapted to their conditions survive.
9
What is it called when ALL of the members of a species die off?
Mutation
Common descent
Extinction
Reproduction
10
DNA in corn plants can be altered by scientists to produce more corn. Identify the process.
Natural selection
Genetic engineering
Ecological succession
Environmental degradation
11
What is the reason why early flowers gradually changed to different types over time?
The genetic material of the flowers stayed the same.
The environments of the flowers stayed the same.
The flowers adapted to environmental conditions.
The flowers’ traits were genetically engineered.
12
Cats have differences in their fur length and patterns which is most likely due to
sexual reproduction
dietary habits
damage from disease
habitat destruction
13
Which group of organisms can show significant trait changes in the shortest period of time?
Bacteria
Fish
Birds
Reptiles
14
Animals may fight, other members of the same species. These behaviors occur as the result of
pollution
competition
conservation
decomposition
15
LaMarck believed giraffes were driven by an inner need to have longer necks to reach the leaves
LaMark's hypothesis was proved
LaMark's hypothesis was disproved
LaMark discovered evolution
16
According to the Natural selection video, what tool do farmers use to get better crops?
Evolution
Common ancestor
Mutation
Selective breeding
17
The snowshoe rabbit fur changes to a lighter color in winter so it blends w/ it's surroundings.
This change is an example of ecological succession
This change is an example of extinction
This change is an example of competition
This change is an example of biological adaptation
18
Feathers, wings, and the hollow bones of birds are examples of ......
adaptations for flight
reproductive structures
responses to stimuli
unnecessary body parts
19
A population of organisms which is at risk of becoming extinct due to changing environment.
extinct species
Endangered species
Species of concern
20
Choosing certain organisms to mate w/ each other to pass on desirable traits to offspring ...
is called asexual reproduction
is called resource acquisition
is called selective breeding
is called natural selection
21
Who is the person responsible for the current theory of Evolution we studied in class?
Gregor Medel
King Phillip
Carolus Linnaeus
Charles Darwin
22
A fox with thick fur would have a survival advantage over other foxes if
the air temperature significantly decreases in winter
a drought occurs, limiting the amount of water available
a new disease appears that infects the foxes
there is more competition for food in the fox population (
23
A horse and a donkey mate and produce a mule. Is the mule a new species?
No mules can't reproduce and so it can not be a new species.
Yes. The mule is a new species and can produce offspring.
24
Which process gives rise to a variety of traits within a species?
internal regulation
sexual reproduction
cellular respiration
dynamic equilibrium (
25
Which group of organisms can show significant trait changes in the shortest period of time?
Plants
Bacteria
Animals
Fungus
26
Organisms better adapted to their environment are chosen by nature to survive/reproduce?
The process above is called Selective Breeding
The process above is called Natural Selection
The process above is called Genetic inheritance
The process above is called Genetic resistance
27

all
three
one
two
29
A puggle is dog produced by mating, a pug and a beagle. This process is an example of
selective breeding
asexual reproduction
natural selection
genetic engineering
30
What is a permanent accidental change to the genetic code called?
A mutation
Extinction
Selective breeding
A species
