Natural selection is a conservative process not a creative one.
And you don’t believe natural selection is the answer?
This is the problem I have with neo-Darwinists: They teach that what is generating novelty is the accumulation of random mutations in DNA, in a direction set by natural selection. If you want bigger eggs you keep selecting the hens that are laying the bigger eggs, and you get bigger and bigger eggs. But you also get hens with defective feathers and wobbly eggs. Natural selection eliminates and maybe maintains, but it doesn’t create.

I was taught over and over again that the accumulation of random mutations led to evolutionary change — led to new species. I believed it until I looked for evidence. …
There is no gradualism in the fossil record… ‘Punctuated equilibrium’ was invented to describe the discontinuity. …
The critics, including the creationist critics, are right about their criticism. It’s just that they’ve got nothing to offer but intelligent design or ‘God did it.’ They have no alternatives that are scientific.
The evolutionary biologists believe the evolutionary pattern is a tree. It’s not. The evolutionary pattern is a web…
