''Unity'' and ''diversity'' are best reconciled by Darwin's Theory of
Evolution. Two major dilemmas related to the study of Evolution are de
scribed. The first, concerning pedagogy, can be solved by teaching the
topic at an elementary level in the middle school so that the Theory
may serve as an ''advanced oragnizer'' and returning with in-depth stu
dy in the last two years of high school. The second, concerning Faith,
is a sensitive issue. Some successful approaches are discussed. The p
lace of Darwin's Theory in the all-elective high school biology curric
ulum is described as well. The role of the Theory regarding explanatio
ns is especially highlighted.
