Unit #3 Study Guide: Adaptation and Natural Selection
Learning Target/related questions
LT #1 I can describe natural selection and
how it relates to the survival of organisms.



Describe what natural selection is…
What is the definition of Fitness?
Understand how organisms
struggle to survive.
 Describe how in each species there
is variation.
 Charles Darwin’s Theory of Natural
Selection…
LT #2 I can describe adaptations and how
they increase the chances of a species
surviving and reproducing.



Provide examples of adaption.
Show how organisms can adapt.
Predict the probability of certain
traits that help an organism adapt.
LT #3 I can describe how mutations occur
and what affect they may have on the
genetic variation among a species.


Describe and define mutation.
Describe the affects mutations can
have on organisms.
 List advantages of each type of
mutation.
 List disadvantages of each type of
mutations.
 How do mutations affect DNA?
LT# 4: I can gather and synthesize
information about the influence of humans
on genetic outcomes.
 Describe and define selective
breeding.
 List two other terms used for
selective breeding.

LT # 5 I can analyze pictorial data to
compare patterns of similarities in the
embryo development across species. I can
identify relationships in embryos that are
not evident in the fully formed anatomy.

Be able to compare embryos and
tell what type of organism that the
embryo will produce.
 Describe the differences between
embryos of different species.
LT # 6 I can apply scientific ideas to
construct an explanation to infer
evolutionary relationships among species.

Describe how bone structure can
help scientist understand the origin
of animals.
 Describe how DNA can help
scientist compare modern day
animals to each other.
 Describe how to find an organism’s
ancestors.
LT # 7: I can use mathematical evidence to
explain how natural selection affects the
amount of a certain trait in a population.




Understand how to figure out
Frequencies in a population
Understand how to read graphs
Understand what graphs mean and
what they are trying to tell you at
each mark/time
Understand how to read charts.
