It's pretty cool that they might be able to bring something like a mammoth, or rather mammoth-elephant hybrid to life, but I'd rather see them use this technique to preserve highly endangered species, rather than something for which there is no natural habitat --that is, if released into the wild, the perturbations might lead to unintended consequences in other species as it has not existed in nature for thousands of years.

But if we must, I'd like to see the dodo bird, the passenger pigeon and the Tasmanian tiger.
