A non-genetic living system? If we define genetics as the inheritance of information from progenitors which can be transmitted to offspring, then how could you have anything that fits anyone's idea of living without having it engage in genetics? Or that it could evolve by any mechanism? To put things another way, if there did exist a non-genetic living system, how would you ever recognize it? (The offspring of such an organism would have no resemblance to their parent except by chance). >Frank Yue >Howard Hughes Medical Institute >taub@hmivax.humgen.upenn.edu This posting <> flame.
