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.

orthogenic evolution

An obsolete term referring to the evolution of biota based on intrinsic changes in the organisms’ genetic constitution, which contrasts to environmentally dependent (bathmic) evolution.

(dahr-win'ē-ăn ev-ŏ-lū'shŭn)
The proposition that the phylogeny of all species is wholly ascribable to random variation (mutation) in genotypes and the operation of preferential survival of those resulting phenotypes most suited to survive in the contemporary environment.

No ideological alternative to Darwinian evolution was offered, though scientifically valid arguments have been proposed by theists, agnostics, and atheists who independently question whether stepwise mutation and natural selection could account for DNA, the cell, or irreducibly complex systems (3, 4, 13, 14).
When I was in my "what to think" cerebral function default mode, I continued to believe in Darwinian Evolution as a Christian, but as soon as I began to think clearly in my "how to think" default mode, I lost my evolution faith.

For example, it came as a surprise to me that many creationists believe not only that new species can evolve but also that such evolution can happen far faster than Darwinian evolution would allow.
In a country where nearly half of American adults have consistently said they believe God created all living things in their present form sometime in the past 10,000 years, intelligent design sounded like a respectable alternative to the amoral, survival-of-the-fittest approach inherent in Darwinian evolution.
Behe likened the acceptance of Darwinian evolution by biologists with the belief of 19th century physicists that light travels, not in a vacuum, but in an invisible substance, highly rigid but having a low density, that permeates all of space.
Among my purposes in writing about the intersection of Darwinian evolution, religion, and government was to show that this road also is marked at a critical junction by behavioral predispositions that bias judgments and decisions against the principles of classical liberalism.

Surely, a Creator who could come up with something as breathtakingly simple and brilliant as Darwinian evolution would be more impressive - more worthy of awe - than one who needed 30 million miracles to create 30 million species?
