1. Read and annotate.
The evolution of two or more species that is
due to mutual influence, often in a way that
makes the relationship more mutually
beneficial…
The ant and acacia tree are examples:
the ant protects the tree and the tree has
special structures that make food for ants.
Flowers and pollinators are also examples
of coevolution.

When two or more species exist together in a
relationship that is mutually beneficial; this is
known as __________.
A. Pollination
B. Benefactors
C. Coevolution
D. Mutuality
1. Read and annotate.
The theory that speciation occurs in spurts of
major genetic alterations that punctuate long
periods of little change. Punctuated equilibrium is
a model of evolution in which short periods of
drastic change in species, including mass
extinctions and rapid speciation, are separated by
long periods of little or no change.

1. Read and annotate.
The process by which Individuals that are better
adapted to their environment survive and reproduce
more successfully than less well adapted individuals
do; a theory to explain the mechanism of evolution.
There are four parts: overproduction, inherited
variation, struggle to survive, and successful
reproduction

NATURAL SELECTION
4. Answer the question.
The process that shows that some individuals are
better adapted to their environment – which allows
them to survive and reproduce is known as
__________.
A. Overproduction
B. Inherited variation
C. Successful reproduction
D. Natural selection
3. Draw a picture representing the key term.
1. Read and annotate.
Marked difference or deviation from the normal or
recognized form, function or structure.
Darwin noticed that the animals and plants on the
Galápagos Islands were a lot like those in Ecuador.
However, they were not exactly the same. The finches
of the Galápagos Islands, for example, were a little
different from the finches in Ecuador. And the finches
on each island differed from the finches on the other
islands. The beak of each finch is adapted to the way
the bird usually gets food.

According to Darwin, ___________ explains why the
tiny birds (finches) of the Galápagos Islands have
marked differences in the function and structure of
their beaks which are adapted for the food available
on each island.

UNIT 6: EVOLUTION VOCABULARY FRAYER MODEL
1. Read and annotate.
An alteration or adjustment in structure or habits, often
hereditary, by which a species or individual improves its
condition in relationship to its environment.
Populations constantly undergo natural selection. After
two groups have separated, natural selection may act
on each group in different ways. Over many
generations, the separated groups may evolve different
sets of traits. If the environmental conditions for each
group differ, the adaptations in the groups will also

ADAPTATION
4. Answer the question.
An alteration or adjustment in structure or habits,
which allows a species or individual to improve its
fitness in its environment is known as a/an
__________.
A. Adaptation
B. Differentiation
C. Natural selection
D. Both A and B
3.
1. Read and annotate.
The evolutionary formation of new biological species,
usually by the division of a single species into two or
more genetically distinct ones. Speciation often begins
when a part of a population becomes separated from
the rest. The process of separation can happen in
several ways. For example, a newly formed canyon,
mountain range, or lake can divide the members of a
population.
SPECIATION
4. Answer the question.
_____ involves the creation of a new distinct species
which can only mate with members of the same
species.
A. Speciation
B. Population
C. Division
D. Extinction

terrain and a new species is formed it is known
as __________
A. Geographic speciation

periods of time rather than by abrupt, major
changes.

UNIT 6: EVOLUTION VOCABULARY FRAYER MODEL
Scientists can determine the age of a fossil more precisely. Absolute
dating is a method that measures the age of fossils or rocks in years.
In one type of absolute dating, scientists examine atoms. Atoms are
the particles that make up all matter. Atoms, in turn, are made of
smaller particles. Some atoms are unstable and will decay by
releasing energy, particles, or both. When an atom decays it
becomes a different, and more stable, kind of atom. Each kind of
unstable atom decays at its own rate. The time it takes for half of
the unstable atoms in a sample to decay is the half-life of that type
of unstable atom. By measuring the ratio of unstable atoms to
stable atoms, scientists can determine the approximate age of a
sample of rock.

4. Answer the question.
The method that measure the age of fossils or rocks in years is
known as
A. Absolute dating
B. Radioisotope dating
C. Speed dating
D. Both A and B
1. Read and annotate.
The proper chronological placement of a feature, object, or
happening in the geologic time scale without reference to its
absolute age. Sedimentary rock has many layers. The oldest layers
are usually on the bottom. The newest layers are usually on the
top. The layers can tell a scientist the relative age of fossils. Fossils
found in the bottom layers are usually older than the fossils in the
top layers. So, scientists can determine whether a fossil is older or
younger than other fossils based on its position in sedimentary
rock. Estimating the age of rocks and fossils in this way is called
relative dating.
4. Answer the question.
___________ is used to estimate the
age of rocks and fossils using the layers of sediment as a
reference – newer fossils are upper layers and older fossils are
found in the lower layers of sediment.
A. radioisotope dating
B. relative dating
C. absolute dating
D. Both B and C
