Then what do you think about all this talk about cloning a mammoth?
One method (probably the easiest / most feasible one) would be to recover some nice juicy semen samples from frozen mammoth carcasses and use them to impregnate living female elephants. Specimens would be obtained from a number of different, uh, specimens, in order to breed a series of generations, to bring the offspring to “mostly” mammoth over a period of, say, 50 years.
I’m surprised that no one has suggested recovering eggs from frozen female mammoths and doing the in vitro whisk with some mammoth semen, then implanting embryos in a number of different elephants. Probably would be less feasible, since the semen would have frozen more quickly after death.
