It is - it just takes a bit of time. This is part of the scientific method - and every single result science has made involved this step. Without the humans interfering, it wouldn't have been a disaster at all, because there were no rabbits in Australia. I fail to see the connection. Again, this is not a problem. There is no knowledge that flows from observation, especially without involving conjecture. You don't like the scientific method very much, do you? Evolution is not completely random, as I have pointed out above: Real time means waiting a few million years - if you can spend that time waiting, you will see it.
