This is the reason why they say Humans are the most dangerous species. You must never mess with mother nature. There is a reason why the species which these scientist have created does not exists naturally. The repercussions of these things can be dangerous and disastrous when nature starts to give it back. Just like what happened in the movie - Jurassic Park. I still remember one of the dialogues in Jurassic Park that goes like this - Nature will find its way. Which nature eventually did find its way in the movie.
