That was Darwin's great idea.

This was Darwin's great idea. Nature - in the form of environmental changes or other factors - can have an effect on a group of organisms similar to the deliberate decisions of an intelligent actor. Nature prefers to maintain certain traits over others, those that confer a functional advantage or survival advantage to the organisms it possesses, causing the traits of the group to change. This change or resulting increase in fitness (adaptation) will not be produced by an intelligent breeder who chooses a desired trait or variation - not entirely by the process. Or, as the eminent evolutionary biologist Francisco Ayala explained, Darwin explained "design without a designer", since "Darwin's greatest achievement was to show that the guiding organization of organisms could be explained as the result of a natural process, i.e., natural selection, without having to resort to a creator or other external actor". Indeed, as early as 1859, most evolutionary biologists began to see the appearance of design in living things as an illusion, very exciting, but ultimately an illusion. For this reason, as we briefly noted above, Richard Dawkins insists in his book The Blind Watchmaker that “biology is the study of complex things that give the appearance of being designed for a purpose.” Or, as Ernest Meyer (father of modern Darwinism) explained: “The true essence of Darwinism...is the theory of natural selection. This theory is very important to Darwinism because it allows it to explain adaptation design in the natural theology by natural means, rather than divine intervention.” Or, as Francis Crick hopes biologists “always keep in mind that what they see is not designed, it is evolved.” Or, as George Gaylord Simpson, one of the architects of the new Darwinian synthesis, wrote in his book The Meaning of Evolution, neo-Darwinism means that "man is the result of a natural, null and void process which has not been taken into account". But if the apparent design is an illusion – if it is merely an appearance – as both Darwinists and neo-Darwinists see it, then it follows that any mechanism that produced this appearance must be completely unguided and unguided! For this reason, the third meaning of evolution – a definition that emphasizes the creative power of natural selection/random mutation and denies evidence of actual design in living systems – is highly problematic for any proponent of divine evolution who emphasizes this meaning of evolution. - Dr. Steven Meyer.
