By AWT the life evolution follows an ancient Oparin's coacervate theory. Coacervates are tiny oily droplets, which are precipitating spontaneously from saturated solutions of various organic compounds, the racemic mixtures of amino-acids and sugars in particular. Under high concentration and some shaking so called reverse micelles or even double layered liposomes can be formed. Such liposomes can behave like walking droplets, described recently:
During this the less successful ("low fitness") droplets disappeared gradually on behalf of those better ones, which have collected the proper surfactants into their liposome bodies. Later the concurrence has lead into preference of droplets, which were not only able to collect surfactants, but even to collect the chemicals, able to synthesize them inside of cells. These droplets has become able to digest food after then, so they become hunters of less successful droplets, not just passive collectors of matter from outside. Of course, such competition has accelerated the evolution a much.
And this saga continues till now...
Note that in this early stage of life evolution the inheritance was provided by physical mechanism completely, simply by dividing of cells together with their interior and surface membranes. By AWT the evolution of life follows exactly the evolution of inorganic matter in more nested dimensional scales, i.e. no ribonucleic acids, chromosomes or other contemporary subtleties were required here. We can consider, this mechanism could be reproduced in vitro under proper conditions without problem. Recently living examples of walking droplets were found: a single-celled giant amoebas of very ancient origin.
From AWT follows, such amoebas were first unicellular organisms by the same way, like sponges of foamy structure can be considered as a first multicellular animals. After all, the tissue of higher organisms is rudiment of foam with flat surface as well. The smaller structures (structures bellow human scale of about 1,7 cm) are having concave structures (organelles), while larger tends to become convex (trees, fungi), because they're kept together by surface tension forces. Therefore first organisms were relativelly large from their very beginning, because electromagnetic interaction itself doesn't provide necessary level of complexity and inheritance at molecular level.
Concerning the creationist approach to life formation, the "intelligent constructer" idea is dual to Aether concept and it can be replaced by it easily. From remote space-time perspective every gradualistic evolution becomes discontinuous stepwise artifact by the same way, like event horizon of black holes, when observed from large distance. Every logical explanation is concentrating non-causal assumptions on background, so it becomes a sort of religion. The belief doesn't differ from adherence to causal logics too much, because both approaches tends to tautology by gradual elimination of postulates.
