Monozygotic twins, or identical twins, are clones of each other. They have the same exact genetic information due to the division of an embryo early in development, which produces two identical embryos. About eight million identical twins are alive in the world; thus, already eight million human clones inhabit the world. Today, the only research is occurring in scientific model organisms. These are organisms that research scientists from around the globe have collected abundant amounts of data.

Adolph Eduard Driesch allowed the eggs of a sea urchin develop into the two-blastomere stage. Then he separated it by shaking it in a flask and allowing them to grow. The cells developed into dwarf sea urchins. Driesch could not explain his experiments and gave up embryology for philosophy (McKinnel 19). During the late seventies and early eighties, there were few scientists still studying . Many had ...
