Firstly, let us look at the scientific facts. To begin with, cloning is a normal phenomenon that occurs in nature. Secondly, we cannot clone a personality or a person's beliefs. Also, we cannot clone a person's memory, which means that the idea that cloning would allow a person to live forever is incorrect. Last of all, clones are not produced in glass jars or any other artificial device.
Cloning occurs naturally in many species on earth, including humans.
The definition of a clone is 'a genetic duplicate of a person or creature'. By this definition, any creature that asexually reproduces creates a clone every time it reproduces. It clones itself over and over. Also included in this definition of a clone are identical twins. Therefore, any creature, including humans, that is capable of giving birth to identical twins is a natural, biological cloning apparatus.
