Coming back to the context, extinction is typically for good because the nature is not cruel but it make unadapted being to go to a mistery place nobody cam back from. Once a species winks out, it survives only in memory and the fossil record and only for some time. Everthing passes, even memories and fossil records. When it comes to the woolly mammoth, however, that rule has now been bent because some people are thinking about bringing the species back. It’s been 4.000 years since the eight-ton, 2,4 meters, elephant-like beast walked the Earth, but part of its DNA now operates inside several litters of four-inch, half-ounce mice created by scientists at the Dallas-based Colossal Laboratories and Biosciences.
