Greetings Art:

"It is a designed in system which contains the ifnormation necessary to
splice together existing information in diffeerent ways. That is hardly
what anyone has in mind for an increase in information, and you know that,
if you reflected on what you wrote."

Ah, but once again, the genetic material may not be new, but the resulting
function is, especially if the function is to recognize an antigen that
never existed before. Influenza viruses change their antigens all the
time, yet the immune system always seems to be able to create molecules
that can recognize them. These new functions constitute new information.
