Identify and describe an example of Adaptation: The birds beak has different shapes and sizes depending on its Diets.
True
False
3
Which of the following organisms could have evolved during the Precambrian time, a bird,butterfly,monkey or bacteria.
Bird.
Monkey .
Butterfly.
Bacteria.
4
During which Era did the movement of animals from the sea to land result in greater diversity of life on earth?
The Mesozoic era
The Precambrian Era
The Cenozoic Era
The Paleozoic Era
5
what is an unused body structure?
structures reduced in size or function have been completed by an ancestor.
broken bones.
Bones that are different sizes.
bones that have different features.
6
What are 4 parts to Darwin's Theory of Natural Selection?
they are Overpopulation, Selection, Genetic Variation and Adaptation.
They are the change in time, Acquired traits,Inherited traits and offspring
they are common structures, similar dna, common ancestors and fossils.
They are Greater competition, Natural disasters, new species and less food.
7
Part 2 Explain how scientists know about the existence of a species that no longer exists.
The fossils start to disintegrate
The fossils start to sink furter in the ground.
The fossils start to appear in the surface.
There are bodily remains of trace fossils.
8
part 2. What Adaptation would improve the chances that Rodent species would survive if its environment changes?
blend in to the new habitat.
being able to eat plants that survive in dry enviorments.
Have a stronger jaw size to eat fruits in drier areas.
have a different type of fur in a desert.
9
Species that have similar structures but different functions What do these structures suggest about their relationships?
they only have a common ancestor not a common structure.
they dont have a common ancestor or a common structure.
they have common structure but they don't have a common ancestor.
They have Common Structures and Common Ancestors.
10
Finches
Picture of a large, wide beak, Finches eat foods with shells like nuts or seeds
Picture a long, thin beak- Finches eat insects and small parts of plants.
11
If Embryos follow similar development pathways.Then what does this suggest?
They make different structures
They have different ancestors
They must have a Common Ancestor.
They have overpopulation.
12
Population is the number of organisms in the same species.
True
False
13
Describe two different types of evidence that scientists use to support the theory of evolution.
Development Similarities Embryology and similar patterns of common ancestor
Common Ancestors most recent species from which 2 differnt sppecies evolved
Common Structure-Similar Structures with different functions.
Similar DNA greater number of amino acids they have in common.
14
What did Charles Darwin observe about the Finches on the Galapagos Islands?
Differences in the feet size among Finches in Different Island.
The Different types of eyes in different areas.
They have different types of beaks depending on their diets and where they live.
Difference in wings among Finches in different Islands.
15
How did photosynthesizing prokaryotes that lived during the precambrian time help life on earth become more diverse.
Cyanobacteria added oxygen to the atmosphere through Photosynthesis.
It release carbon dioxide into earths athmosphere.
It makes sugar so animals can survive
It causes prokaryotes to die off.
16
When and Why did Dinosaurs become extinct?
A tsunami wiped up all the Dinosaurs in the Paleozoic Era
Mesozoic Era. A asteroid hit earth and killed all the Dinosaurs on earth.
A Big Earthquake wiped out all the Dinosaurs in the Cenozoic Era.
A Volcano killed all them in the Precambrian time.
17
which of the following would similar DNA provide evidence for, Fossils, Genetic structural, or Development patterns?
Fossils.
Development patterns.
Similar DNA.
Genetic Structual.
18
Evolution is the process by which populations change over many Generations.
True
False
19
the law of superposition and relative dating. Where is the oldest layer of rock in a undisturbed bed of sedimentary rock
It would be on the top
it is a part of metamorphic rocks.
It is part of igneous rock.
The oldest rocks would be on the bottom and the youngest is on the top.
20
Natural selection/ A Giraffe with a long neck survives better in dry seasons. They also breed much better that year.
True
False
21
Provide one inference on why trilobites might have disappeared.
They started to loss there food source.
Environment changed, lack of water,change in the water temperature.
They started to loss their habitats.
There were more competition in the water.

Transitional Fossils Definition
Fossils that form in Magma.
Fossils that form in water.
is any fossilized remains of a life form that exhibits traits.
Fossils That form on the surface.
24
Fossils are formed when a dead organism is covered by a layer of sediment or mud.
False
True
25
Part 1. Trilobites, an organism that once lived on the seafloor, cannot be found living anywhere on earth.

26
What role does evolution play during Cenozoic Era. (what defines this Era)?
water animals first go on land.
The Primates Began to evolve.
The Dinosaurs dominated the earth.
Dinosaurs began to extinct.
27
How dose relative dating help determine the age of a fossil.
It determines whether a fossil formed before or after another fossil.
It determines how old a fossil is.
It determines the size of a fossil.
It determine the structure of 2 fossils.
28
Variation is within a species there are naturally occurring differences.
True
False
29
Is this evidence of common structures, Similar DNA or similar embryological development?
Similar embryological development
Similar DNA
Common ancestors
Common structures
30
Examples of Transitional fossils.
The bones change over time.
The fossil getting older over time
The bones of animals have never changed.
The fossil changing color.
31
A Catastrophic Disturbance that resulted in mass extinction marks the boundary of which two Eras.
The Cenozoic and Paleozoic Era.
The Cenozoic and Precambrian Era.
.The Precambran and Mesozoic Era.
