For Once Listen to Hollywood

So scientist at the University of Melbourne and the University of Texas have discovered a way to get genes from extinct animals (Link). Now forgive me if I sound a bit cold hearted here but why on Earth do we need to bring back animals that went extinct? What good could possibly come from it? 

Let me put it this way. When I was first taking my anthropology classes I was taught that in the course of evolution a species either has to move, adapt or die when a new challenge is given. This is why we do not have legitimate Neanderthals promoting Gieco, only modern humans in costume. Obviously the animals they are trying to bring back failed somewhere along the way which is why they are extinct now. 

Yes, I understand many animals went extinct because of something humans did. The dodo bird is a prime example, if humans hadn't introduced new species that killed the dodos they would still probably be here today. However, that still does not dismiss the fact the dodo died off because it was unable to move or adapt. Left with the only option the dodo slipped off into the sands of time.

Then there is the issue of what will happen if we reintroduce some species into a ecosystem not designed for them. I can help but to use the example of Jurassic Park (the film, the book is long and wordy). I sure most people have seen it in the 15 or so years it's been out so they will know what I am talking about when I say I don't want a T-Rex running through downtown San Diego. Granted they probably won't be able to bring back dinosaurs and it's questionable whether they can bring anything at all, but I'm still concerned they are even trying. 

Let's just hope this idea goes the way of the dodo because honestly extinct animals are probably best left that way. I mean would you want your species to be brought back from the dead only to be either over hunted again or turned into a cute and cuddly pet? Probably not.
