Be Careful about Cloning谨慎对待克隆After a series ofinitialexperiments andcorrections, the scientist’s hard workpaid off when thetwincloneturkeys werehatched with normalfeatherandclaws. Thisbreakthrough possibly enabled people to bring theiradored pets back to life. However, itbothered himfrom time to timethat their health wasin poor condition because they wereunable toresistillnesses. Thisdrawbackcasthimdown. Merely2 weeks later, the clones and theircarrier died, whichstruckfrustration into his heart.
