Members of PRNCYB-L may be interested in some articles by Dan McShea.

McShea,D.W. 1991. Complexity and evolution: What everybody knows.
Biology and Philosophy, 6, 303-324.

His original article questioning whether complexity actually
increases with evolution.

McShea, D.W. 1994. Mechanisms of large-scale evolutionary trends.
Evolution, 48, 1747-1763.

Distinguishes between passive evolutionary trends, and actively
driven trends with ways of testing which is which (and real
examples of both).

McShea, D.W. 1996. Metazoan Complexity and Evolution: Is there a trend?
Evolution, 50, 477-492.

Applies last paper to trends in complexity. Discusses
complexity with respect to the task, preferring a practical
(if rather weak) measure to an a priori one. Concludes with
"an emphatic agnosticism" because there is not definite evidence
either way. Ends on nice quote: "...the point here is not to
deny directionality exists. Something may be increasing. But
is it complexity?".
