Cloning is becoming more than a sci-fi fantasy. Natural cloning in asexual organisms has existed way before the first Jurassic World movie. Artificial cloning was first conducted in 1885 on salamanders by Hans Driesch. Gene cloning, reproductive cloning, and therapeutic cloning are three types of artificial cloning that are currently possible. Through these processes, pieces of our genome, entire livestock animals, and even your beloved pets can be replicated.
Starfish are asexual animals that can naturally regenerate identical starfish after being broken into two pieces. Simple organisms like bacteria also possess the same ability. They can divide themselves into two identical daughter cells. In complex animals, fertilized eggs split to create twin siblings. However, these offspring are not genetically identical to their mother.
