I started a thread "The Definition of Alive" on PFs v2.0 and now I have another question pertaining to the definition. Heredity was said to be the definition of life.

Another paradox is: [/b] But, I have done the honor of actually searching for a more complete definition. And of course, there is the frame work for the definition: To add to heredity, "Virtually all authors who have considered life from the point of view of molecular biology have regarded the property of self-reproduction as the most fundamental aspect of a living organism. —John D. Barrow and Frank J. Tipler, The Anthropic Cosmological Principle" So, how do we create a definition of life using this given data?
