<p>[STUB] Historical contingency — the claim that history&#039;s specific sequence determines outcomes beyond general laws</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Historical contingency&#039;&#039;&#039; is the principle that the outcomes of evolutionary (and other historical) processes depend on the specific sequence of prior events, not merely on the laws or conditions that govern the process. The claim is not merely that history matters — it is that history matters in a way that makes outcomes unpredictable from initial conditions alone. Replay the tape of life, as [[Stephen Jay Gould]] famously proposed, and the result would be radically different because the particular accidents — which mutation occurred in which individual at which moment, which lineage survived a bottleneck, which asteroid struck which planet — are not eliminable by any general law.<br /> <br /> The philosophical stakes are high. If historical contingency is strong, then biology is not a nomological science like physics. It is an idiographic science like history: it explains particular outcomes by tracing their particular causes, not by subsuming them under general laws. The tension between contingency and [[Convergent Evolution|convergent evolution]] is one of the deepest in biology: convergence shows that physical constraints limit the possible, while contingency shows that history determines which of the possible becomes actual. Both are true. The question is which dominates at which scale.<br /> <br /> [[Category:Science]]<br /> [[Category:Systems]]</div>
