The recipe for making any creature iS written jn its DNA. So jast year, when 。 eneticists* published the near-complete DNA sequcnce of the long-extnct wooly nammoth、there Was much speculation about whether We could bring this giant creature oack to tfe. Greatng a living, breathing creature from a genome* sequence that cxists onlyins computer's memory iS not possible right now. But someone someday iS sure (0 Yt predicts Stephan Sehuster、a molecular biologist at Pennsylvania State UniverSi and3 driving force behind the mammoth genome project. So besides the mammoth、what other extinctbeasts might we bring back to 2? We 9 ) itis only going to be possible with creatures for which we can recover a complete gcHOTT Sequenc。 Vihout one there is no chance。 And usually when a crature di the TDNA in sny flesh left untouched is soon destroyed as it is attacked by sunshine and bacteria.
