REVIEW ARTICLE
Hemostasis and irreducible complexity
W. C. Aird

Summary. Coagulation evolved as a means to stem the loss of blood and to defend against pathogens. The complexity of the clotting cascade has been cited as evidence for the existence of divine intervention. The objective of this review is to draw on the debate between creationists and evolutionary biologists to highlight important evolutionary principles that underlie the hemostatic mechanism. I propose the following: (a) as with all biological systems, the hemostatic mechanism displays non-linear complexity; (b) the cellular response represents primary hemostasis owing to its place in the evolutionary time scale and functional importance; and © the rapid evolution of the hemostatic mechanism in vertebrates is testimony to the power and versatility of gene duplications and exon shuffling.
