STANDARD B5: EVOLUTION AND BIODIVERSITY
Students recognize that evolution is the result of genetic changes that occur in constantly
changing environments. They can explain that modern evolution includes both the concepts of
common descent and natural selection. They illustrate how the consequences of natural
selection and differential reproduction have led to the great biodiversity on Earth.
B5.1d
Explain how a new species or variety originates through the evolutionary process
of natural selection.
B5.1e
Explain how natural selection leads to organisms that are well suited for the
environment (differential survival and reproduction of chance inherited variants,
depending upon environmental conditions).
B5.1f
Explain, using examples, how the fossil record, comparative anatomy, and other
evidence supports the theory of evolution.
B5.1g
Illustrate how genetic variation is preserved or eliminated from a population
through natural selection (evolution) resulting in biodiversity.
B5.2x Molecular Evidence
Molecular evidence substantiates the anatomical evidence for evolution and provides
additional detail about the sequence in which various lines of descents branched.
B5.2a
Describe species as reproductively distinct groups of organisms that can be
classified based on morphological, behavioral, and molecular similarities.
B5.2b
Explain that the degree of kinship between organisms or species can be estimated
from the similarity of their DNA and protein sequences.
B5.2c
Trace the relationship between environmental changes and changes in the
gene pool, such as genetic drift and isolation of subpopulations.
B5.3 Natural Selection
Evolution is the consequence of natural selection, the interactions of (1)
the potential for a population to increase its numbers, (2) the genetic
variability of offspring due to mutation and recombination of genes, (3) a
finite supply of the resources required for life, and (4) the ensuing
selection from environmental pressure of those organisms better able to
survive and leave offspring.
B5.3A
Explain how natural selection acts on individuals, but it is populations
that evolve. Relate genetic mutations and genetic variety produced by
sexual reproduction to diversity within a given population.
B5.3B
Describe the role of geographic isolation in speciation.
B4.3C
Give examples of ways in which genetic variation and environmental
factors are causes of evolution and the diversity of organisms.
B5.3d
Explain how evolution through natural selection can result in changes in
biodiversity.
B5.3e
Explain how changes at the gene level are the foundation for changes in
populations and eventually the formation of new species.
B5.3f
Demonstrate and explain how biotechnology can improve a population
and species.
Research Questions:
Choose one (1): 250 words, work cited MLA include a graphic
1. There are a number of myths about evolution find six (6) and discuss them. Be
sure to debunk the myth and support it with an objective from above. Here is a
starting point:

2. Evolution in Action: Lizards moving towards live birth. Review this article from
National Geographic: I will have it posted on my website:
http://news.nationalgeographic.com/news/2010/09/100901-science-animals-evolutionaustralia-lizard-skink-live-birth-eggs/
Review the article and write about the findings. Be sure to relate this to objectives
B4.3C, B5.3A, B5.1e
3. From Fin to Hand: http://discovermagazine.com/1996/jan/fromfintohand653
Write about this article and indicate how the Hox Gene works. What are
researchers finding in regards to the Hox Gene and evolution. Be sure to connect
this to the objectives above. Other link:

4. There have been a number of times where states have tried to legislate how
evolution is taught in the classroom. Recently Tennessee has been facing
legislation House Bill 368 which will force science teachers to teach about the
controversies in evolution, which is another way of saying that they must teach
about creationism. Tennessee faced a similar trial like this in the 1920s. You may
have heard of it…The Scopes Trial. Write about the view from both sides of the
argument. Try to have the same number of resources for each side. Finally, give
your thoughts. Must have at least 3 resources for both sides for a total of 6. Here
is the link for the House Bill: http://www.capitol.tn.gov/Bills/107/Bill/HB0368.pdf
