The origin of Stem cells

The emergence of stem cells on Earth has occurred at least three times. 1) The emergence of stem cells that created the Animals kingdom. 2) The emergence of stem cells that created the Plants kingdom. 3) The emergence of stem cells that created the Apicomplexa kingdom. New stem cells may emerge to create a new kingdom in the future. I've proposed this theory in 1992 for the first time. This theory states that: The origin and evolution of higher animals and plants has started by coexistence between two or more primary multicellular. In this type of symbiosis are mixed, all the genes of bionts together and placed together only in a cell nucleus. (Bionts = The members of symbiosis.) Cell containing mix of genes, does cell division and in different conditions any gene makes its own cells. The process by scientists as defined "distinction". Mixgene is a kind of symbiosis, that where is two different types of cells, that its both genes shared only in a single cell. . In other words, the body of all plants and animals are composed of a few primitive multicellular existence. Each tissue indicates a primary multicellular.
