Natural selection has been wiping out species with subpar adaptive strategies. Among the casualties: dinosaurs, mammoths, Neanderthals, and all manner of megafauna that we’d all love to see first-hand. Alas, mother nature hasn’t been particularly forgiving of species selected against: for four billion years, extinction meant extinction. That is until 2009 when scientists used frozen tissue to successfully clone the Pyrenean ibex, a kind of goat native to the Pyrenees Mountains between Spain and France, making it the first species to become un-extinct.
