2. Comparative Vertebrate Morphology
Deals with anatomy and its significance
We use “COMPARISON” as a tool.
Emphasize the functional and evolutionary
themes.
For example:
two types of tail shapes among fishes
3.
4. As we compare.......
What we notice? …..D _ _ _ _ _ _ _ _ _
After observing the D __________
Whats next....?
We asked WHY?
6. Comparison of parts highlights these
differences and help us to pose a question.
Functional analysis helps answer our
question and give us better understanding
of animal design.
Why does an elephant had a cylindrical
limbs?

8. Comparative analysis
Could be used in historical or nonhistorical context
Historical – we refer to evolutionary event.
Nonhistorical – refers to the outside look and
usually extrapolative (process of estimating)
used in testable predictions.

Discussed the 3
issues of evolution
fact
course
mechanism
24. FACT – species change through time
COURSE – progressive changes in species
along an ascending scale, from the lowest to
the simplest to the most complex
MECHANISM – need itself produces heritable
evolutionary changes- when environment or
behavior changed, an animal developed new
needs to meet the demands of the
environment.
25. George Frederic Dagobert Cuvier
Have the same belief
with Linne
That animals do not
change.
The efficient design fo
each animal is
evidence that it could
not have changed
since creation.
