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?".
