Five operational principles utilized in phylogenetic analysis are outlined: Hennig's Axiom, the Principle of Relativity, the Conundrum of Convergence, Popper's Law, and the Phylogenetic Uncertainty Principle. The constraints imposed by these principles require that we come to understand and recognize the limits to certainty in phylogenetic analysis. This uncertainty complements current ideas on the operation of punctuational and stochastic factors in macroevolutionary processes. A method of phylogenetic analysis, stochastic mosaicism, is applied to several invertebrate groups. This technique suggests a conceptual model of evolution which, when contrasted to Sewell Wright's adaptive landscape model, more clearly reflects the evolution of Baupläne in space-time.
