  This study explores the emergence of life through a simulation model
approach. The model "Multi-set chemical lattice model" is a model that allows
virtual molecules of multiple types to be placed in each lattice cell on a
two-dimensional space. This model is capable of describing a wide variety of
states and interactions in a limited number of lattice cell spaces, such as
diffusion, chemical reaction, and polymerization of virtual molecules. This
model is also capable of describing a wide variety of states and interactions
even in the limited lattice cell space of 100 x 100 cells. Furthermore it was
considered energy metabolism and energy resources environment. It was able to
reproduce the "evolution" in which a certain cell-like shapes adapted to the
environment survives under conditions of decreasing amounts of energy resources
in the environment. This enabled the emergence of cell-like shapes with the
four minimum cellular requirements: boundary, metabolism, replication, and
evolution, based solely on the interaction of virtual molecules.
