By AWT the life evolution follows an ancient Oparin's coacervate theory. Certain liposomes can behave like walking droplets, described recently.
We can imagine, such droplets were precipitated from waves of ancient lakes at places, where organic compounds were pre-concentrated by wind and solar radiation and they were thrown at coast surface, covered by various surfactants. The droplets are attracted to them, so they started to climb around coast, collecting these materials in their cells. The most successful droplets become so large by such way, they fragmented into smaller ones under impact of next breaker wave, and whole process has repeated many times.
