The intermediate products are only there to be processed further. Their existence is therefore only of advantage, if a further processing is possible. The accumulation of useful information demands the existence of nearly completely closed reaction compartments, in solution, like for example some kind of inshore water the reaction partners would be lost by diffusion . Each of today s cells is surrounded by a semi-permeable membrane consisting mainly of lipids and proteins. These complex organization units did certainly not exist right from the beginning.
Life is a process of constant optimization.
The gain of useful information due to mutations and selection of an evolution unit is a long and in effect not too successful way. The combination of units complementary to each other is far more efficient. The characteristic of microspheres to fuse can be regarded as a proof that such fusions did indeed occur. The interaction potential increases with the expression and the development of signals at the outer surfaces of the protocells. Their existence causes selectivity and allows to distinguish between same or complementary to each other and foreign.
