Related to darwinian evolution: Evolutionary Theory

dar·win·i·an ev·o·lu·tion

the proposition that the phylogeny of all species is wholly ascribable to the combined effects of random variation (mutation) in genotypes of the members of a stock as a result of the operation of undirected accidents with consequences to their phenotypes and the operation of preferential (but by no means certain) survival of those resulting phenotypes most suited to survive in the contemporary environment. The proposed system survives largely because of genetic factors that avidly conserve the ontogeny of the stock.

Darwinists now have many websites in which the experts gush about how wonderful Darwinian evolution is and the laymen (invariably less informed than Nagel) gush back about how wonderfully clear the experts have made evolutionary theory to them, dispelling all doubt and rendering the theory obligatory for all clear thinking people, so that only those wedded to a religious fundamentalism could doubt it.

Proponents of intelligent design claim the Cambrian explosion of 545 million years ago, when the body plans of the ancestors of most animals developed, occurred too rapidly be explained by the gradual process of Darwinian evolution. Biologists Mark Farmer and Andrea Habura point out in their paper that unicellular protistan evolution lasted 1 billion years, providing the genomic diversity from which multicellular organisms arose during that remarkably fertile period.
