life. What are some things that they have in common?
a.
Both have a point of common ancestry.
b.
In both, descendants inherit features from previous ancestors.

In both, descendants more closely resemble their recent ancestors than more
distant ancestors.

Label distinct
history, shared history,

shared history
.
The
green dot = common
ancestor.

area that shows the best
common ancestor of
tuna and parrot.
The area that shows the best
common ancestor of tuna and parrot is the
intersection between the baseline and the
second to last branch.

Folder 3
1)
Which is more closely related to caimans—hares or parrots?
a)
Hares
b)
Parrots
2)
Cladograms represent
hypotheses
about evolutionary
relationships and
who is more
closely related to whom.
3)
Fill in the table by listing and describing the derived trait for each letter.
Letter
Derived Trait
Describe
A
Vertebrae
The skeletal units of the spinal column or backbone, that
protects the spinal cord and support the body.
B
Bony Skeleton
Although bone tissue evolved earlier a true bony skeleton
does not appear until the ancestors of bony fishes and
consists of hardened bone, not cartilage
C
Four Limbs
Possessing four limbs for terrestrial Locomotion unless
secondarily lost or modified for other types of locomotion
as in the flippers of whales or wings of bats animals with
four limbs are called tetrapods
D
Amniotic Eggs
The egg can be laid on land due to the presence of a
fluid-filled amniotic sac that cushions and protects the
developing embryo.
E
2 Skull openings
Two additional openings besides the eyes and nostrils on
the side of the school behind the eyes animals with such
openings are called diapsids.
F
Hair
Find filaments growing from the skin consisting of special
epidermal cells and providing insulation
4)
Which features do humans, hares, caimans, and parrots share that the other three
lineages did not inherit?
a)
Bony skeleton
b)
Hair
c)
Amniotic egg
Folder 4
1.
What does the (+) mean?
The feature is found in the organism
2.
What does the (0) mean?
The feature is not present in the organism
3.
What does the (-) mean?
The feature cannot be marked because it does not apply to the organism
4.
What does a (?) mean?
It is undetermined whether the feature is present or not.

Directions
Please do some out of class research to help you answer the questions below. Please include a url and page/video title to indicate where you found your information.
Prompt
Sometimes, changes or “mutations” occur that prevent genes from doing their job properly. Certain mutations in the BRCA genes make cells more likely to divide and change rapidly, which can lead to cancer.
If you inherit a mutated version of a BRCA gene, does this mean you are guaranteed to develop cancer? What other changes must occur for cancer to develop? Citation required.

6. A child has brown hair and brown eyes. His father has
brown hair and blue eyes. His mother has red hair and
brown eyes. The best explanation for the child having
brown hair and brown eyes is that
(1) a gene mutation occurred that resulted in brown
hair and brown eyes
(2) gene expression must change in each generation
so evolution can occur
(3) the child received genetic information from each
parent
(4) cells from his mother's eyes were present in the
fertilized egg

Part 1 The Symptoms
Imagine that you work at the medical examiner's office for a major metropolitan city. As Chief Medical Officer, you
investigate suspicious deaths and provide toxicology services for the county. Unfortunately, it's been a busy week. In
the past five days, seven people have died, all with similar symptoms. It is your job to examine the data and determine
the cause of death for these victims.
The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy
nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning,
the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby
hospital, where she was pronounced dead.
That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an
apparent heart attack. Sadly, the victim's brother and fiancée also collapsed later…
