3
If an organism cannot adapt to its environment it will
starve
reproduce
survive
become extinct
4
The older the fossil...
The smarter the organism.
the deeper in the ground it is found.
The closer to the surface it is found.
Must have been studied by Charles Darwin.
5
When is a trait most likely to be passed on to the next generation?
when it serves no purpose to the organism
when it gives the organism a lare supply of water
when it prevents the organism from finding a mate
when it helps the organism survive
6
Differences between members of the same species are called
variations
evolutions
adaptations
mutations
7
True or False: Only traits that are controlled by genes can be acted upon by natural selection.
False
True
8
What example of adaptation did we observe in our predator/prey toothpick lab?
the toothpicks were all clumped together
small size helps the organism hide
camouflage
the predators are smarter than the prey
9
Darwin noticed many differences among similar ____ throughout the Galapagos Islands.
DNA
people
organisms
land structures
10
What is characteristic of the kingdoms fungi and animalia?
they both have cell walls
they are both autotrophic
they are both heterotrophic
they both have prokaryotic cells
11
The reason that evolution occurs is because species gradually change over many generations as
as they are outcompeted
as they camoflauge the best
they become better adapted to their environment
as they adapt their beaks

primates
sharks
crocodile
rabbits
14
Similar body structures among organisms (like our arm bones) are called:
homologous structures
homozygous structures
dominant structures
DNA
15
In peppered moths, all moths have dark wings. One is born with light wings. This is....
adaptation
mutation
cross-breeding
evolution
16
What was Charles Darwin's main contribution to science?
he thought of evolution
he was the first person to witness animals evolving
developed the moderntheory of evolution by natural selection
he argued against evolution
17
If a group is separated off long enough, they may evolve new traits and form a new __________.
migration
species
evolution
trait
18
One way to tell the exact age of a fossil is by using:
relative dating
Google
absolute dating
history books
19
This happens between organisms. It is caused by limited food and other resources.
overproduction
adaptation
variations
competition
20
What is a common ancestor?
an animal that is related to many other species

24
What are the two processes involved in the carbon cycle?
ammonification and respiration
photosynthesis and respiration
nitrogen fixation and denitrification
evaporation and condensation
25
How are fossils formed?
when sediments harden and preserve the print or the bones
when an animal dies and the bones are scavenged
when an animal dies and ocean water covers it.
when sediments wash away the print or the bones
26
