Instead, you use blogs.

Unless the researchers have access to pre-1935 bacteria sitting in lab refrigerators, the claim that the genes actually evolved new proteins via mutation is dubious since we have no pre-1935 bacterial samples to actually do a comparison with, especially in the case of NylC. The claim that NylB’s nylon eating ability evolved by gene duplication from a non-functional NylB-prime gene could just as well be interpreted that a functionless NylB-prime gene is a defective copy of a functioning NylB gene!


What’s the proof new nylon eating genes actually evolved after 1940, or is it just speculation? Slam dunk proof would entail having strains of pre-1935 bacteria and then comparing it with the strains after 1935 that supposedly evolved new genes. Is that the case? No. Just speculation which began in 1977 but got less defensible over the next 40 years as more bacteria and non-sequence-homologous genes were discovered to have nylon eating capability.

The above is a word for word copy&paste from here:

Do you actually know what any of that means?
