Darwinism and the warm little pond
A natural origin to life was not an original tenet of Darwinism. The position of Charles Darwin in The Origin of Species was that the Creator breathed life into a few forms or into one (Origin, pages 421-422), and Natural Selection worked upon these or this multicellular life form to produce the many species found in the world today.
Certainly, Darwin had a minimalist position concerning religion, and it may be said that Darwin never firmly nor fully defined his position regarding the origin of life, but Darwin did not adhere to a philosophy of Naturalism. Thus, NeoDarwinism extends the scope of Evolution and natural processes involving Natural Selection far beyond the original claim.
Origin of life theorists are keen to link themselves to Darwin by citing a letter Darwin wrote in 1871 in which he wrote that life may have emerged in a warm little pond. Whether this was as some bacterial slime or as a Mudskipper is open to all interpretations.
Creation of the first cells
I propose with the Theory of Nanocreation that the first living cells were created as such. There are three basic types of single cell organisms; they are the Archaea, Eubacteria and eukaryotic Protista.
Archaean cells have DNA, RNA and proteins. Archaea have different components to their plasma membranes and cell walls than Eubacteria, and their ribosomal RNA has different base sequences. Archaea are very small cells that are adapted to very extreme environments.
Eubacteria are prokaryotic cells like Archaea, often somewhat bigger. They have cell walls composed of peptidoglycan. They reproduce asexually like Archaea and have many forms of nutrition with metabolic functions taking place in the cytoplasm of the cell.
The first eukaryotic single cell organisms belonged to the Protista kingdom. They are much bigger cells than bacteria with DNA in a nucleus surrounded by a nucleus membrane. The metabolic functions of the cell take place in membrane-bound cell organelles found within the cytoplasm. Later eukaryotes became multicellular.
The creation of whole unicellular organisms means that DNA, RNA and proteins, as well as other macromolecules such as lipids that form membranes were created together and designed as living cells. Support for the idea that DNA, RNA and proteins came into existence simultaneously in a living cell is that the genetic system does not function at all without all three components being present.
