Re: Oral presentation
Genomics, please give us a model which is proved as the cradle of life.

No models have been demonstrated to provide a satisfactory explanation for the origin of biological life. That includes your model. While your hypothesis does offer a somewhat different approach to looking at the origin of life, it still leaves a lot to explain, like the origin of gram-positive and gram-negative membrane structures.

Genomics: "...it still leaves a lot to explain, like the origin of gram-positive and gram-negative membrane structures."

Fox's microspheres are gram-positive and gram-negative protocells: http://jb.asm.org/content/85/2/279.full.pdf
It is good point to start.

Please give us paper(s) with gram-positive and gram-negative proto-membrane structures. Thanks.

But that doesn't explain the transition from gram-positive prokaryotes to gram-negative prokaryotes. In other words, just imagining the origin of a simple membrane bag does nothing to explain the origin of the earliest life forms empirically known to exist -- bacteria.

Anyways, I'm still a little confused about your model. How does your model explain the origin of (1) the first membrane-bound cell systems, (2) the origin of ATPases and other early molecular machinery?

Nobody explanes these things you want to be explaned. If you watched my oral presentation (https://youtu.be/Hn7A-1w0tuQ) you know that I have many quastions too without any excplanations.

You missed my main idea: the first step in the origin of life is the creation of the physical conditions necessary for life. Only after that evolution can begin (the origin of different types of cells, enzymes and ATPases, etc.). According to the membrane approach, the necessary physical conditions can only occur when there is sodium pump in plasma membrane. This is the first step according to this approach. If this step is not passed, no evolution is possible because only the living cell can evolve. There is no experimental evidence of origin of sodium pump in prebiotic conditions. If there is no such evidence, then the membrane approach is not confirmed. Other questions I have formulated here: http://www.bioparadigma.spb.ru/...Preview.and.Highlights.pdf
I'm talking only about the first step in the origin of life. You talk about life itself.
