haven't worked out the kinks yet on modern animals. Only 22 species have been cloned with 19 species able to result in an adult.

So, in spite of the thought its a common and easy thing to do, its not.

The next issue is economics. If you were to choose an animal to clone would it be an animal that is broadly useful to human kind and have a return on investment to pay for the costs of development, or would you choose an animal that is expensive to keep and a great public interest as a curiosity, but won't solve an important problem or make enough money (even in zoo ticket sales)?

P.S. Don't tell me the economics of tourism and ticket sales for views will pay for the cost of cloning a DoDo....its still more valuable to clone a mundane animal like a super cow that produces lots of milk and/or meat.
