In a brief article about the nature of life on Earth I posit a case for pre-cell evolutionary life and for "purposeful" in-cell life organization. The article is available at http://www.biobitfield.com/henis.
Recently I came across an interesting report of work suggesting that "Cells reprogram in 24 hours, erasing molecular memory of parents, could shed light on clones", presented at http://www.nature.com/nsu/020415/020415-12.html.
I suggest that "molecular memory" is a "technical's concept and term" and that the phenomenon thus inaptly designated is an expression of "purposefullness of in-cell life organization".
At each and every formation of replicated in-cell life the purposeful organization of the cell's inhabitants (the live beings complex we call genome, the commune of genes) continuous in the direction of parent-cell momentum until it is impressed that it is not in the position and in the dedicated task framework in which its parent cell was…and it seeks and sometimes assumes a new dedicated task framework.
Is not this is, in essence, the meaning of a Stem Cell?
