"Life," in this contest is defined as follows: "--- any system which can
independently do all four of the following:"
1. "Delineate itself from its environment through the production and
maintenance of a membrane equivalent, most probably a rudimentary or
quasi-active-transport membrane necessary for selective absorption of
nutrients, excretion of wastes, and overcoming osmotic and toxic gradients,
2. Capture, transduce, store, and call up energy for utilization (work),
3. Actively replicate, not just passively polymerize or crystallize, and
4. Write, store, and pass along seemingly conceptual information that 'gives
orders' for what is to be manufactured in the future, and to actually bring
to pass those processes and "factory products" out of linguistic-like coded
(codon) messages('recipes') into physical biochemical, biological, and
Are the protocells of Fox alive according to the above definition?
