The world was astonished by this feat, because he drew attention to the theoretical possibility of cloning humans. The clones were made from "cultured cells derived from easily obtained tissue should bring numerous practical benefits in animal husbandry and medical science." "Cloning is based on nuclear transfer, the same technique scientists have used for some years to copy animals from embryonic cells. Nuclear transfer involves the use of two cells.
