Oh and anyway, if you manage to "make" one tasmanian tiger, how will they breed and become populous again? If you made two tasmanian tigers with the same gene, and they were of different sex, it would be the same gene reproducing with itself. Those of you that breed guppies know that if incest happens you get deformities...
You'd need like, hundreds of preserved genes from different animals in order to bring a healthy population back to life.
Or just keep making one animal at a time with the same gene.
Just being creative here. But if tasmanian tigers came back to life and the whole population didn't have diverse enough gene variations, they'd all have weaker immune systems etc. Then if one of them gets a virus and it mutates and it also affects humans, it'd become like in I Am Legend...
