Evidence for Evolution POGIL
Model #1Family
Characteristics
1.
2. Organisms in row 2 shares traits with parents
3.
4. The organisms in the 3rd line are related to first
line b/c the first line are grandparents to the 3rd
line containing similar characteristics found in
both lines
5. a. All organisms in the 3rd generation have at
least 1 similar trait as the grandparents
b. These traits were passed from parents to
offspring due to DNA being duplicated and passed
on
6. a. All organisms exhibit at least one trait that is
not the same as the grandparents
b. The people that married into the family
introduced new traits to the family. Or, mutation
could have occurred during crossing over
introducing new traits to the family.
7. The line of offspring that shares the most traits
with the parent organisms in the first line is row 2
(the children of the parents). Based on evidence
found in model 1, the children (row 2) exhibit
traits that link to the original parents. The
organisms in the 3rd generation will have new
traits compared to the 2nd generation because of
individuals who married into the family.
8. The line that shares the most DNA with the
parent organisms in the first line is the children
(line 2)
9. The original parent organisms in the first line in
Model 1 get their traits from their ancestors.
Model #2:
Forelimb
Similarities
10.
11. Humans use our forelimbs to grab things, lift
things, and to build things. Dog use their forelimbs
for to walk, run, play catch, and keep balance.
Birds use their forelimbs to fly. And whales use
their forelimbs to swim.
12. a. The first similarity is that the ulna and radius
are next to each other across all 4 animals. The
second similarity is that the metacarpals connect
the carpal to the phalanges.
b. Differences among the 4 animals:
1. The structure of the phalanges are different
2. the gap between the radius and the ulna
3. The length of the humerus
13. The blue print that determines the structure of
the limbs is found in the DNA.
