Science is a very important indicator of the future. Every scientific advance or discovery gives us a clue about what the future will hold for society. Perhaps the most amazing scientific discovery in recent times was the birth of Dolly the sheep. Dolly was the first successful cloned animal - that is, she was the first animal ever to be created from a single adult cell. She is an exact copy of her biological mother. Since Dolly's birth, there has been debate about what this means for society in the future - because if we can clone sheep, we can surely clone humans. Some think that there are already signs that such things will eventually happen. For example, couples in the United States who can't or don't want to have children by natural methods can now select the human egg and sperm they want through catalogues, audiotapes or even computer order systems. One journalist has commented, "Ordering a frozen embryo is a little more emotionally complicated than ordering a home-delivered pizza - but not so different logistically". (Hewitt 1998).
