-Student can describe the molecular processes and/or environmental factors by which
mutations occur (e.g., insertion, deletion, substitution, or UV radiation in sunlight).
-Student can describe mutations as random changes or occasional mistakes that occur
when DNA is copied, which when in egg or sperm cells, can be passed on to the offspring.
-Student can describe that changes caused by mutations will often be harmful, but a small
minority of mutations will cause changes that allow the offspring to survive longer and
reproduce more.
2< (below
standard)
-Student can predict how a given trait or mutation could allow a species to survive and
reproduce in a given environment.
-Student has partial knowledge of mutations.
34
Standard: LS3C (Species Diversification)
The great diversity of organisms is the result of more than 3.5 billion years of evolution that has filled
available ecosystem niches on Earth with life forms.
Rubric:
4 (above
standard)
-In addition to a performance of 3…
-Student can create evolutionary trees when given a list of organisms and their traits.
-Student can provide examples of organisms that have similar genes due to evolution.
3 (at
standard)
-Student can describe Hox genes.
-Student can explain that species alive today have diverged from a common ancestor (e.g.,
by interpreting diagrams representing an evolutionary tree).
-Student can explain how filling an available niche can allow a species to survive.
2< (below
standard)
-Student can describe that genes in very different organisms can be similar because the
organisms all share a common ancestor.
-Student has partial knowledge of species diversification.
35
Standard: LS3D (Evidence of Evolution)
The fossil record and anatomical and molecular similarities observed among diverse species of living
organisms provide evidence of biological evolution.
Rubric:
4 (above
standard)
3 (at
standard)
2< (below
standard)
-In addition to a performance of 3…
-Student can describe more than three evidences of evolution (e.g., fossil record, vestigial
organs, analogous structures, DNA similarities).
-Student can describe three evidences of evolution (e.g., fossil record, vestigial organs,
analogous structures, DNA similarities).
-Student has partial knowledge of the evidence of evolution.
36
Standard: LS3E (Relatedness of Organisms)
Biological classifications are based on how organisms are related, reflecting their evolutionary history.
Scientists infer relationships from physiological traits, genetic information, and the ability of two
organisms to produce fertile offspring.
Rubric:
4 (above
standard)
-In addition to a performance of 3…
-Student can describe the similarities and/or differences of given organisms in terms of
biological evolution (e.g., Darwin’s finches had different beaks due to food sources on the
islands where they evolved).
3 (at
standard)
-Student can describe how new species evolve and provide examples.
-Student can describe that scientists use physiological traits, genetic information, and/or
the ability of two organisms to produce fertile offspring to determine the evolutionary
relationship between organisms.
-Student can describe the relationship(s) among organisms based on similarities and/or
differences in physical and/or functional characteristics.
2< (below
standard)
-Student can describe the evolutionary relationship between two organisms and/or
identify the organisms that are most closely related given a diagram representing an
evolutionary tree.
-Student has partial knowledge of the relatedness of organisms.
