In effect, protein engineers are using the power of random change plus intelligent design to see what if anything will improve function.
This is intelligent design that sweeps the planet, covering not biology alone, but chemistry, geology, and physics.
David Barash is an evolutionary biologist known for delivering a yearly talk to his students disabusing them of the idea that science can be reconciled with religious faith.
The problem is, none of these people cite papers or other writing by researchers on intelligent design, like the work done by Douglas Axe on protein evolution probabilities.
There are a limited number of explanations available for how cosmic fine-tuning came to be. Actually, there are three.
