Vision: Evolution’s Witness
Instructor: Ivan Schwab, Department of Ophthalmology, School
of Medicine
Description: Did you ever wonder how an owl is able
to find its
prey at night? Do you suppose the term "eagle eye" is
really justified?
Do fish see colors? Do you suppose that the term "four eyes" can be
applied to any species except humans? Did you wonder how far a jumping spider
can really see? What does a fly do with all those images? Did it ever occur to
you that diving bird can see under water without goggles and you can't? How, do
you suppose, do reptiles with no eyelids clean their eyes? Why don't
woodpeckers
get retinal detachments or concussions? When snakes shed their skin
do they shed
their corneas? How old are eyes? What was the first eye? Are you curious about
the answers? Students will be expected to learn comparative visual physiology
and understand the evolutionary forces that guided these adaptations. Emphasis
will be on resource development. With the instructor's direction students will
use available resources to generate the questions of comparative
visual physiology
and anatomy.
Format: We will meet for 2 hours each week for eight
weeks. Students
will be expected to perform the weekly reading, and to participate in the class
discussion. Emphasis will be placed on self discovery and
organization. Text will
be web based articles. Each student will be expected to choose a
species and prepare
a oral and written presentation on an aspect of comparative visual physiology
or anatomy. Grading: Grades will be based on
class participation,
and oral and written presentation.
About the Instructor: Dr Schwab is a Professor of
Ophthalmology
with an interest in comparative ophthalmology. He is the cover editor for the
British Journal of Ophthalmology and provides a cover image and essay on vision
