It's ridiculous that a patent system exists that would allow someone to even try to patent the result of billions of years of evolution.
The problem arises, when do you draw the line? When you spend thousands of man hours in a scientific lab and millions of dollars to piece together a bit of understanding, was it discovered or created?
The answer is often somewhat obvious. But I imagine that, behind closed (or semi-closed) doors, there are a lot of very persuasive people arguing for a very permissive definition of "create".
While it's probably hard to properly classify everything accurately the first time you see it, hopefully time lets us get a better perspective and quickly re-classify.
