BIG IDEA I:
THE PROCESS OF EVOLUTION
EXPLAINS THE DIVERSITY AND
UNITY OF LIFE.
Connecting evolutionary
changes in a population over
time to change(s) in the
environment by describing
these examples:
Describe several sources of evidence
from multiple scientific disciplines
that support biological evolution using
the graphics:
9% =.09 = ss = q2
(f)s = q = Square root of .09 = .3
p = 1 - .3 = .7
2pq = 2 (.7 x .3) = .42 = 42% of the
population are heterozyotes (carriers)
If 9% of an African population is born
with a severe form of sickle-cell anemia
(ss), what percentage of the population
will be more resistant to malaria
because they are heterozygous(Ss) for
the sickle-cell gene?

After graduation, you and 19 friends build
a raft, sail to a deserted island, and start a
new population, totally isolated from the
world. Two of your friends carry the
recessive cf allele, which in homozygotes
causes cystic fibrosis.
A. Assuming that the frequency of this
allele does not change as the population
grows, what will be the instance of
cystic fibrosis on your island?
B. B. Cystic fibrosis births on the island is
how many times greater than the
original mainland. The frequency of
births on the mainland is .059%.
C. Causes for SA and CF in these
examples?
Describe conserved
features and core
processes as
evidence of common
ancestry
How do phylogenetics
reflect ancestral
differences and similarities?
What data supports the
concept of common
ancestry within and between
phylogenetic domains for all
life?
Speciation & Extinction
Discuss these graphics as
evidence of isolating mechanisms
leading to speciation.
Discuss models that
represent evolution
within a population by
using these graphics.
Evaluate hypotheses about the
origin of life on Earth.
