Artificial life, or a-life, is an interdisciplinary science focused on artificial systems that mimic the properties of living systems. 
    In the 1990s, new media artists began appropriating and adapting the techniques of a-life science to create a-life art; 
    Mitchell Whitelaw’s Metacreation is the first detailed critical account of this field of creative practice. 
                
  
    A-life art responds to the increasing technologization of living matter by creating 
    works that seem to mutate, evolve, and respond with a life of their own. 
    Pursuing a-life’s promise of emergence, these artists produce not only artworks, but generative and creative processes: 
    here creation becomes metacreation.
