Answer:
Cloning is an artificial means of asexual reproduction, whereby an identical genetic copy of an organism is produced. A clone is a genetically identical descendant of one parent.
In this sense, cloning occurs always with human intervention; although many plants (and some animals, such as sea anemones) spontaneously reproduce asexually with genetically identical offspring, this is usually not called cloning.
Animal cloning has opened the field to a series of ethical discussions about its potential applications in morally questionable sectors, such as human cloning.
