Researchers have cloned an an adult mammal for the first time. The next step, some say, could be making copies of human beings.

Scientists took genes from a 6-year-old ewe and and somehow placed the genes in unfertilized genes, then attempted to impregnate other sheep. Soon, a young lamb named Dolly, born in July, became an exact genetic copy of her mother.

While the cloning of animals may have many positive possibilities, it also has many negative effects.

Cloning could speed up the process of genetically engineering animals, lower the cost of many materials that come from animals and provide larger amounts of food.

For example, genetic cloning could allow researchers to produce super milk-producing cattle that produce 10,000 more pounds of milk per year.

Cloning just one lamb was a miracle in itself — of 277 embryos, only one led to a lamb.

But these researchers have no business playing God. This could be the start of something that could be abused by greedy investors in the future. Cloning is just unnatural. We just hope Mother Nature continues to find ways to foil humankind.
