The supposed sudden emergence of the enzyme nylonase has been a chief talking point for the power of evolution for many years.
New proteins had to come from somewhere. Susumu Ohno had an idea.
Yesterday, I described how some biologists claim that the enzyme nylonase demonstrates that it is easy to get new functional proteins.
A significant problem for the neo-Darwinian story is the origin of new biological information.
