Abstract

Based on set theory, a phylogenic tree of materials is obtained by arranging physical attributes of present organisms, such as 'homeostatic', in the order of the evolution that preceded life. The tree indicates that thirty attributes should have been acquired by a material system in advance to 'physical border' representing a cell membrane, and also that two different series of attributes, which start at 'homeostatic' and 'singular distribution, ' merge at 'physical border.' These results suggest that cell membrane had been generated by highly complex mechanisms consisting of, at least, the stabilization in a set of molecules and the repulsion between the sets. The tree also suggests the candidates of reactions for the creation of 'physical border.' Computer simulation shows that physical borders are created in the candidate system. This method is applicable to the origins of other important attributes of life.
