How does the mutation or natural selection produce new information?
Would you agree that the human genome and the chimp genome contain different information? Is this difference in information due to the difference in DNA sequence? If you answered yes to both then you must also agree that a change in DNA sequence due to a mutation is new information. If you answered no to either question then please explain.
Do you have an empirical example of a code or language that occurs naturally?
The orbitals of atoms is a good example. Hydrogen, the simplest element, has the code 1s^1. Helium is 1s^2. Read more
