Topic: Diversity of Life
Which Standards are students learning in this unit?
Standard 1.1.A Understand that: Scientists conduct investigations for a variety of reasons
including ton explore new phenomena, to replicate other’s results, to test how well a theory
predicts, to develop new products, and to compare theories. (Essential)
Standard 1.1.B. Understand that: Science is distinguished from other ways of knowing by the
use of empirical observations, experimental evidence, logical arguments and healthy skepticism.
(Essential)
Standard 7.2.B The great diversity of organisms is the result of more than 3.5 billion years of
evolution that has filled available niches with life forms. The millions of different species of
plants, animals, and microorganisms that live on Earth today are related by descent with
modification from common ancestors. (Essential)
Standard 7.2.F Genetically diverse populations are more likely to survive changing
environments. (Essential)
Standard 7.3.A The expanding ability to manipulate genetic material, reproductive processes,
and embryological development creates choices that raise ethical, legal, social and public policy
questions. (Compact)
By the end of this unit, students will be able to…

 Conservation
 Extinction

 Artificial selection
 Adaptation
 Classification
Topic: Speciation
Understand:
Do:
Evolutionary processes
including extinction are
influenced by the environment
Observe and analyze evidence
to determine whether there
may be an evolutionary
relationship between two or
more organisms.
Human actions can affect the
genetic diversity of organisms
l
Science is a social enterprise,
but alone it only indicates
what can happen, not what
should happen. The latter
involves human decisions
about the use of knowledge.
Describe some ways that
human impact may be
affecting the evolution of
other organisms.
Design and conduct scientific
investigations to control all
but the testable variable in
order to test the hypothesis.
Which Standards are students learning in this unit?
Standard 7.2.A Evolution is a change in allelic frequencies of a population over time. The theory of
evolution is supported by extensive biochemical, structural, embryological, and fossil evidence.
(Essential)
Standard 7.2.C The process of natural selection occurs when some heritable variations that arise from
random mutation and recombination give individuals within a species some survival advantages over
others. These offspring with advantageous adaptations are more likely to survive and reproduce, thus
increasing the proportion of individuals within a population with these advantageous characteristics.
When populations become isolated, these changes may accumulate and eventually result in new species
(Essential).
Standard 7.2.D Evolution does not proceed at the same rate in all populations; nor does it progress in a
linear or set direction. Environmental changes have a strong influence on the evolutionary process. Other
factors that influence evolution include: sexual selection, mutation, genetic drift, and genetic
modification. (Important)
Standard 7.2.E Organisms are classified into a hierarchy of groups and subgroups based on similarities
in structure, comparisons in DNA and protein and evolutionary relationships. (Compact)
Standard 7.2.F Genetically diverse populations are more likely to survive changing environments.
(Essential)
Standard 7.3.C DNA is analyzed to determine evolutionary relationships, study populations, identify
individuals, analyzed genetics disorders. (Important)

Species evolve through descent with
modification, thus allowing them to adapt to
different environments.
Environmental pressures can influence the
evolutionary process. A change in a species
over time does not follow a set pattern or
timeline.
Do:
Use information from cladograms or
other evolutionary trees or timelines
along with molecular data to support
a claim of possible relationships
between two or more organisms.
Use evidence and reasoning to
formulate a logical explanation for
where a population is in the process
of speciation.
Explain the roles of geographical
isolation, reproductive isolation and
natural selection on the evolution of
new species.
Topic: Natural Selection/ Nature of Science
Which Standards are students learning in this unit?
Standard 1.1.E Understand that: In communicating and defending the results of scientific inquiry,
arguments must be logical and demonstrate connections between natural phenomena, investigations, and
the historical body of scientific knowledge. (Essential)
Standard 1.1.C Understand that: Theories in science are well-established explanations of natural
phenomena that are supposed by many confirmed observations and verified hypotheses. (Essential)
Standard 7.2.C The process of natural selection occurs when some heritable variations that arise from
random mutation and recombination give individuals within a species some survival advantages over
others. These offspring with advantageous adaptations are more likely to survive and reproduce, thus
increasing the proportion of individuals within a population with these advantageous characteristics.
When populations become isolated, these changes may accumulate and eventually result in new species.

A scientific theory is a wellsubstantiated explanation of
some aspect of the natural world,
based on a body of facts that
have been repeatedly confirmed
through observation and
experiment. Such fact-supported
theories are not "guesses" but
reliable accounts of the real
world.
Understand:
Genetic diversity naturally
occurs in any population due to
mutations and recombination of
genes.
Scientific explanations must
adhere to criteria such as use of
appropriate evidence, logical
consistency of reasoning, and
basis in historical and current
knowledge.
Scientists are influenced by
societal, cultural, and personal
beliefs and ways of viewing the
world.
Scientific theories allow
scientists to make predictions
about as yet unobserved
phenomena.
Do:
Analyze natural selection
simulations and use data
generated from them to describe
environmentally favored traits
are perpetuated over generations
resulting in species survival
while less favorable traits
decrease or may lead to
extinction.
Describe a human intervention
that has altered the course of
evolution for a given species.
Apply evolutionary theory to
explain the existence of multiple
species of similar organisms.
Explain why homogeneous
populations maybe more
vulnerable to environmental
changes than heterogeneous
populations.

Do:
Evolution results from natural
genetic variation developing
diversity in populations that
share resources. If diversity is
not maintained, resources
become scarce and mass
extinctions become likely.
Analyze and interpret data to create a
logical argument or explanation regarding
applied evolutionary concepts.

conservation issues surrounding invasive
species or an argument regarding antibiotic
resistance concerns)
Understanding evolutionary
concepts can aid stakeholders in
making informed and responsible
policy decisions.

present arguments which defend
explanations and proposed actions.
