Maybe not. Henry Nicholls asks whatit would take to bring the woolly mammoth back from the dead. Henry Nicholls In1990 the late Michael Crichton gave the idea of reviving extinctspecies a slickly plausible and enormously entertaining workout in hisnovel Jurassic Park . At that time the longest genome that had everbeen sequenced was that of a virus. The best part of 20 years on,hundreds of animal genome sequences have been published. This week, forthe first time, the genome of something undoubtedly charismatic anddefinitively extinct joins the list: the mammoth ( Mammuthusprimigenius ) ..........¼ÌÐøÔĶÁµã»÷²é¿´¡·¡·¡·¡·¡·¡·[ Last edited by titi066 on 2008-11-20 at 13:25 ] |
