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.
Proteins are composed of a linear string of amino acids, often hundreds in length, and perform all sorts of important tasks in the cell.
Some bacteria developed the ability to consume nylon. No need for ID in biology?
