A clone is an identical copy of a plant or animal, produced from the genetic material of a single organism. Plant physiologist Herbert Webber coined the term in 1903 to refer to a plant created from parts of another plant other than the seed, such as cuttings, bulbs, and buds. Plants have created their own clones using this method for billions of years, long before humans existed on Earth, and humans have engaged in the practice of creating new plants by using non-seed parts of other plants for thousands of years. Many common fruits, vegetables, and ornamental plants are produced in this way from parent plants that have especially desirable characteristics. (Opposing Viewpoints)
