Origin of life in membraneless protocells

Uma nova perspectiva se abriu no tema da busca para explicar as origens da vida. O surgimento da primeira membrana sempre foi motivo de debate, pois se calculava que era necessário aparecer primeiro uma membrana para possibilitar a formação e desenvolvimento das primeiras biomoléculas, como enzimas, proteínas e RNA. Um forte candidato para solucionar o mistério são as bolhas como se vê formando na água. Mas agora um grupo de cientistas descobriram que os coacervados – uma espécie de protocélula – que não possuem membranas, podem conter em si biomoléculas de RNA e a ausência de membranas facilita a transferência de pedaços curtos da biomolécula entre indivíduos, fornecendo assim um complexo maior de informações. Mas quando focalizamos toda esta situação, ou quando lemos um artigo como esse, tendo em mente a formula da Matrix/DNA, nos vem a mente todas as soluções para as questões e se vê novos aspectos do problema. Deixarei aqui registrado o link para o artigo para retornar e destrinchar cada item citado. Enquanto isso, abaixo vai cópias de meus comentários publicado pela PHYS.ORG:

Great job, but, still a scientific wrong worldview is avoiding to see the obvious here. From where Nature got the mechanism of self-replication? What else was – in the state of the world at that time and before that time – doing self-replication ? What means, which is the natural force, that produces the function of self-replication? Who drove the terrestrial atoms composing rocks, water, air, suddenly to such never seen before new connections that produced biomolecules? And why complex biomolecules?
There is a new theory with a new world view that suggests explanations for all these questions following a unique logic line: linking cosmological evolution with biological evolution we can find the picture of an evolutionary link, like a kind of non-biological DNA. The picture is at my website and it solves all these questions. Of course, while I can not show the real link, it is merely a theory. But theories are the drivers for science to find out the next missing information.

Well… you are right. Before life’s origins, there were membranes in the sky, composed as membranes and working as membranes: the horizon event surrounding galactic nuclei. So, why Nature should to do the hard work of creating from nothing (applying magics?) the natural phenomena called “membrane”, if it already exists? Life which real name is “biological system” was generated here by the forces and elements existing in a planet belonging to a surrounding natural system called “solar”, which is inside other called Milk Way. It is always systems down. It is the same and unique evolutionary lineage. Of course, galaxies are our ancestors like bacteria are.So, really, membranes came first. I can’t understand why humans arbitrarily decided to separate universal evolution into two blocks without any evolutionary link between them… can you explain me? Thanks…
