Note that the same two new genes, both of which were necessary to utilize nylon waste, appeared in two different forms of bacteria. Also note that it actually happened in a laboratory (that means in a necessarily small population of bacteria) within only a few months: Nylon was invented in 1935 and industrial production began some years later. Two species of bacteria now feed on nylon waste, which didn't exist prior to the 30's. Both flavobacterium and pseudomonas have two new genes, designated nylA and nylB, that allow them to feed off a nylon waste product. BOTH genes are needed. Experimenters from Osaka U selected a strain of pseudomonas from NZ that had never been exposed to nylon waste. They cultured pseudomonas where nylon waste was the only source of carbon and nitrogen. Within a few months, a strain appeared with nylA and nylB genes. This isn't Darwinian evolution. This isn't even evolution at all. It's the APPEARANCE of two new genes, BOTH of which are absolutely vital, in a very short time in a small population of bacteria. Using the word evolution for this implies we understand how this happens. We don't!
