The first Stem cells on Earth: How a cell has found this ability for first time that produces the various cells?

If a bacterial cell divided more than hundred times, the similar bacteria arise finally. If a Euglena cell divided more than hundred times, the similar Euglena arise finally. In a cells colony, the cell divides and produces the similar cells in colony. Bacteria, unicellular and colonies are the first cells on earth. These cells can only, create the similar cells. But a Sponge’s zygote (stem cell) can produce three types of cells during cell division (Amoeboid cell, Flattened surface cell and Collar cell). This book answers the following questions: 1) How a cell has found this ability for first time that produces the various cells? 2) At what times these cells appeared on earth? 3) Are stem cells found only in the multicellular? 4) Are stem cells found in the unicellular? Excellent animals and plants have been come to existence by getting beside each other of these simple polycellulars. cells are not components of animals and plants, but their components are simple polycellular that were living as free in the nature in a period. In other words, animals and plants body have come to existence by symbiosis between some simple polycellular. This is a completely new theory.

I was born in 19 March 1971 in East Azerbaijan in Tabriz. Besides academic studies, I was interested in the size of animals/plants and the effect of gravity of Earth on their size. From 1990, I started to write papers in this field. In the year 2000 and 2001 I published two books "Earth gravity and animal Evolution" and "The ABC of Evolution".
