Extinction Since the dawn of time thousands of species from the animal kingdom have ceased to exist. We should be thankful for that because it would be pretty hard to live with dinosaurs and mammoth's! Now I'm not saying, for instance, that the Spotted Owl won't be missed, but these things have been happening as a part of nature for eons!
Clone a wooly mammoth? For what purpose? So that some scientist can bring to life a creature that no longer exists and has no habitat in the modern world? And why? Would it make him feel like a GOD?? No cloning! Tempting, but no! It's wrong.
