Many organisms have been observed to acquire various new functions which they did not have previously (Endler 1986). Bacteria have acquired resistance to viruses (Luria and Delbruck 1943) and to antibiotics (Lederberg and Lederberg 1952). Bacteria have also evolved the ability to synthesize new amino acids and DNA bases (Futuyma 1998, p. 274). Unicellular organisms have evolved the ability to use nylon and pentachlorophenol (which are both unnatural manmade chemicals) as their sole carbon sources (Okada et al. 1983; Orser and Lange 1994). The acquisition of this latter ability entailed the evolution of an entirely novel multienzyme metabolic pathway (Lee et al. 1998). Bacteria have evolved to grow at previously unviable temperatures (Bennett et al. 1992). In E. coli, we have seen the evolution (by artificial selection) of an entirely novel metabolic system including the ability to metabolize a new carbon source, the regulation of this ability by new regulatory genes, and the evolution of the ability to transport this new carbon source across the cell membrane (Hall 1982). Such evolutionary acquisition of new function is also common in metazoans. We have observed insects become resistant to insecticides (Ffrench-Constant et al. 2000), animals and plants acquire disease resistance (Carpenter and O'Brien 1995; Richter and Ronald 2000), crustaceans evolve new defenses to predators (Hairston 1990), amphibians evolve tolerance to habitat acidification (Andren et al. 1989), and mammals acquire immunity to poisons (Bishop 1981). Recent beneficial mutations are also known in humans, such as the famous apolipoprotein AI Milano mutation that confers lowered risk to cardiovascular disease in its carriers.

Why would natural selection require creative power? It doesn't require any intelligence at all -- just a harsh environment that makes it more difficult for less effective / efficient random iterations to survive. Then multiply that by hundreds of millions of iterations.

Dismissing a feature as leftover isn't the fault of evolution -- it's a fault of the scientist. There should at least be a potential former use identified. But that doesn't make evolution less viable.

The evidence that you claim is missing for genetic mutations increasing complexity over long-time frames is simply not supported by the wealth of evidence from multi different disciplines. I'm sure Dr. John Sanford is quite persuasive, but the words of one individual do not refute the decades and centuries of evidence that dispute this.

It is indeed thought terminating to continue to hold a belief if it is not supported by evidence. The idea that organisms were formed more or less as they are, and that natural selection is only capable of minor adjustments is something that is empirically testable by observing genetic lineage, and the fossil record. But the hypothesis fails under the weight of our observations. It does really appear that organisms have a direct lineage all the way back to the most primitive forms of life. In light of this, we must reject the hypothesis and accept what the evidence tells us. To do otherwise is allow dogma to cloud our judgement.

I know I said this already, but I'd like to repeat my opinion on the intersection between religion and science: I do not believe that the creator of the universe would want us to reject the tools that they have given us to understand their universe. To do so would be to dismiss and condescend their achievement. So why do you choose to do this with evolution? Despite it being one of the most well-supported scientific theories we have? As you mentioned, you accept natural selection, so clearly you accept aspects of the theory despite it contradicting your theology. I'm sure your beliefs contradict your theology all the time across many aspects of your life. Surely you accept that a text from the bronze-age written by fallible humans and influenced by the ideas of the very specific culture that produced it is not literally 100% true?
