The controversial technique known as cloning is the creation of a genetically-identical copy of a living organism. Although the technology was groundbreaking in the field of genetics, it has stirred up a heated debate. Plants, animals, and DNA can be cloned.

On April 21, 2009, fertility doctor Panayiotis Zavos claimed that he cloned 14 human embryos, implanting 11 of them into the wombs of four women.

The FDA approved the sale of meat from cloned animals on January 15, 2008. The FDA released a report stating: "meat and milk from cow, pig, and goat clones and [their] offspring are as safe as food we eat every day."

Dolly the Sheep was the first mammal to be successfully cloned using adult DNA. Humans could theoretically be cloned, which raises many ethical questions and concerns. Therapeutic cloning was successfully accomplished in 2001 at a biotech lab in Worcester, Massachusetts. Stem cells were extracted and implanted into a piece of human tissue. Instead of 'cloning a human person, the DNA was cloned to create a replacement organ.

In March 2009, Italian gynecologist Severino Antinori, who made headlines in 1994 after allowing a 64-year-old women to give birth, announced that he had successfully delivered three cloned babies. The babies were allegedly cloned using cells from two nine-year-old boys and one nine-year-old girl. All three babies were said to be in excellent condition. Antinori provided no further proof of his announcement.Breitbart.com: Italian doctor says he has cloned three babies
