Species Revival: Should We Bring Back Extinct Animals?
People were fantasizing about reviving extinct forms of life long before Hollywood embedded the idea into our collective consciousness with Jurassic Park. Can we really do it? And if we can, why should we?
The first question would seem to have a straightforward, if hardly simple, answer. Scientific developments—principally advances in cloning technologies and new methods of not only reading DNA, but writing it—make it much easier to concoct a genetic approximation of an extinct species, so long as DNA can be retrieved from a preserved specimen. (Sorry, Jurassic Park fans, the dinosaurs lived too long ago for their DNA to survive until the present.)
