アブストラクト：

In this report we propose a model of evolution of cell membranes.We at first explain the basic characterisitics of  all membranes 
focusing membrane transport.Then we introduce Kaneko et.al.'s protocellular model.In their model all  molecules have equivalent 
permeability.But this assumption has a weak biological ground as explained above.Thus we propose a primordial membrane 
dynamics in which the permeability of a cell depends on the contents in  itself.We study how the permeability of protocells 
evolves along with autocatalytic cycles in the cells.

The permeability of the cell menbrane depends on membrane proteins.In the primitive Earth environment, however, it  is said that 
no protein exists.Although there is an evidence that small molecules help permeability in protocellular  membranes.It is still big 
problem how cells obtain the ability for verious molecules.Therefore we should study the  evolution of permeability as one of the 
main issue in the origin of life.
