Life's biologic complexity: Automatic molecular actions (Introduction)

dhw: What exactly is your theory?

DAVID: How much swimming have you done in your life. If you and your wife decided to play house in the water, how would she give birth or nurse? This is some of the simple stuff land mammals had to reconfigure their bodies to do. Simple decision? Fish are yummy? Sounding whales can do so because of enormous changes in their lungs. The conversion from land to sea makes no sense to me unless evolution is a drive for complexity. Evolution certainly found it here.

dhw: So if evolution is a drive for complexity for the sake of complexity, all these changes are no problem and make perfect sense to you, but if evolution is a drive for improvement, which involves greater complexity, they are a problem and make no sense? The changes will be the same whatever the purpose.

You have again side-stepped the issue of the necessity of huge physiologic change required to enter the ocean. It makes no sense because it is so difficult to accomplish through mutations. Why did life's evolution try it? It is the dumbest improvement I've seen if viewed logically, but it is complex.
