Return to David's theory of evolution (Evolution)

dhw: More dodging! ALL life is biochemical! And you omit to mention that you have your God using biochemistry to design phenotypical changes, 99% of which had no connection with what you say was his one and only purpose. And you omit to mention that all the biochemical phenotypical changes prior to the Cambrian were unnecessary because he created our ancestors and foods de novo during the Cambrian! It’s you have forgotten the lovely bacteria from which we have descended. How can we have descended from them if your God designed our ancestors without any predecessors?

DAVID: The bold is pure nonsense. The biochemistry developed in the Ediacaran is the same biochemistry that is the basis of the biochemistry used in the Cambrian. And surprise! We are still using much of the same bacterial biochemistry started in them. Predecessors is a word that requires an analysis of phenotype. All phenotypes are dependent upon the underlying biochemistry available to them. Please try to see evolution at two distinct levels!

dhw: Of course all phenotypes depend on biochemistry! That’s why I said all life is biochemical. Your theory that he designed our ancestors – his only purpose - from scratch (the Cambrian gap) makes “pure nonsense” of your theory that first he had to design earlier life forms (“mistakes”, “failures”) which had no connection with us, regardless of the fact that they all use the same biochemistry.

Not nonsense. Early forms required less complex biochemistry. As biochemistry advanced, forms advanced. The final form is our brain which is based upon the highly complex biochemistry of neurons. Pre-Cambrian forms developed the necessary complex biochemistry to allow the Cambrian animals with brains!

DAVID: God knew completely organisms would fail. To repeat for the nth time: He designed limited adaptability and designed new species as needed.

dhw: Thank you for confirming your belief that he knew his design would lead to 99% mistakes/failures, and that the reason they died was his faulty design which prevented them from adapting to new conditions outside his control. This process was repeated until the Cambrian allowed him to design new species which were not even based on the 1% of survivors since he designed them from scratch. Some of these survived the great “mess”, and evolved (through his dabbling) into us and our food. Please indicate any points you wish to reject.

Not stated as I would but it fits my thinking.

DAVID: Failure to survive by brilliant designs making room for new designed species.

dhw: So now your God clutters up the planet with 99% of life forms he designed so that chance changes in conditions would get rid of them and make room for another 99% of mistakes until the right conditions happened to arrive etc., as bolded above. And this is brilliant.

It is evolution not based on the struggle for survival. As for conditions, not adversely acting, the increase in oxygen allowed the Cambrian. Are we here or not? Is our creation brilliant or not? Darwin theory of survival driving evolution tells us we shouldn't be here. Our somewhat equivalent ape cousins have done just fine for six million years with simple brains.
