Currently, zoos follow existing livestock breeding techniques fairly closely, but scientists such as Dr. Benirschke and Dr. Conway see the day when sperm and tissue banks challenge extinction in special cases. According to researchers, the day will come when the embryo of, say, a snow leopard may be implanted into the surrogate womb of a lion, or even transported to another country in the body of a rabbit.
''The concept is simple,'' Dr. Benirschke says. ''When the time comes the cells of an extinct female can be thawed, and perhaps generations from now a new baby will enter the world.''
But, for the immediate future, the significance of a frozen zoo lies in its promise to overcome the most severe drawback of captive breeding one that threatens the very identity of the species. Inbreeding from repeated use of limited stock can create unwanted, harmful and sometimes lethal genetic abnormalities. The only safeguard is a broad and variable gene pool access to the genes of hundreds of specimens from each species.
