David, thanks for your excellent posts. You get right to the heart of some important issues. Rather, they are the products of an intelligently designed system.
Evolution is used for stabilization and minor adaptations.
New lifeforms and new complex features appear only with supernatural intervention. Evolution is used for stabiizaton and minor adaptations, but under certain circumstances can also result in the appearance of new lifeforms and new complexity. I wouldn't say. Both have their appeal. But no new feature is introduced.
