Mutation can either:
1. Duplicate genes
2. Change existing genes
3. Delete existing genes
Novel traits can arise by doing both 1 & 2 in sequence. Gene A gets duplicated so you have AA. The second one is changed so now you have AB. Rinse and Repeat.
Using any definition of information ever proposed, this is an increase of information.
So if you have 2 copies of the same book, do you have twice as much information?
And back to my original question:
Have scientists ever observed a mutation that introduced new genes?
Is there ANYONE out there who can answer this question?
