Defining Life

 
The August issue of SEED has a wonderful article by Carl Zimmer, the best science writer on the planet. The article, The Meaning of Life, has just appeared on the SEED website so you can all read it [THE MEANING OF LIFE]. You should read it.

Zimmer asks an important question,

We create life, we search for it, we manipulate and revere it. Is it possible that we haven't yet defined the term?

What do you think of the definition(s) in the article?
