RECONSIDERING THE DEFINITION OF LIFE

Abstract

  According to my previous works, the definition of life is reconsidered. A point of my view regarding the definition of life is based on taking into account the relationship between a life-like system and the environments. The analysis of life-like systems regarding the metabolism, replication and mutation of information, assignment method between information and function, individuality, and subjectivity towards the environments clearly demonstrated the analogies among life-like systems at different hierarchical levels. Based on these analysis, civilization is regarded as a similar type of biosystem to cell-type organisms. The analysis of characteristics and emergence of civilization as comparing to cell-type organisms would imply both the emergence of life and the definition of life.
