Why? it has been repeated at least 500 times in college labs - not hard or expensive to do. Here is a relatively neutral site on abiogenesis: http ://en.wikipedia.org/wiki/Abiogenesis It discusses a dozen or so differ possible forms of Abiogenesis. I am inclide to think this is how it started: Please Register or Log in to view the hidden image! They spontaneously form so oceans has millions of them still today.This is figure's original caption: Three main structures phospholipids form spontaneously in solution: the liposome (a closed bilayer), the micelle and the bilayer. More quoted from link: "A protocell is a self-organized, endogenously ordered, spherical collection of lipids proposed as a stepping-stone to the origin of life. A central question in evolution is how simple protocells first arose and differed in reproductive contribution to the following generation driving the evolution of life. Although a functional protocell has not yet been achieved in a laboratory setting, the goal appears well within reach. "Self-assembled vesicles are essential components of primitive cells.... A boundary is needed to separate life processes from non-living matter. Researchers Irene A. Chen and Jack W. Szostak (Nobel Prize in Physiology or Medicine 2009) amongst others, demonstrated that simple physicochemical properties of elementary protocells can give rise to essential cellular behaviors, including primitive forms of Darwinian competition and energy storage. Such cooperative interactions between the membrane and encapsulated contents could greatly simplify the transition from replicating molecules to true cells. Furthermore, competition for membrane molecules would favor stabilized membranes, suggesting a selective advantage for the evolution of cross-linked fatty acids and even the phospholipids of today. This micro-encapsulation allowed for metabolism within the membrane, exchange of small molecules and prevention of passage of large substances across it. The main advantages of encapsulation include increased solubility of the cargo and storing energy in the form of a chemical gradient." Billy T adds: quite often there would be "surface inclusions" some of which could do as the selective spots /ports in human membranes do - facilitie life processes.
