Q Does all of this not just beg the question of what is a working definition of "life"?
A Not at all. Life is that which possesses some or all of the following characteristics:
Homeostasis: Regulation of the internal environment to maintain a constant state
Organization: Being structurally composed of one or more cells, which are the basic units of life.
Metabolism: Transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolism).
Growth: Maintenance of a higher rate of anabolism than catabolism. A growing organism increases in size in all of its parts, rather than simply accumulating matter.
Adaptation: The ability to change over a period of time in response to the environment.
Response to stimuli: A response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion, for example, the leaves of a plant turning toward the sun (phototropism) and by chemotaxis.
Reproduction: The ability to create the next generation.
Q Why do you do this?
A well it looks to me like a question followed by one persons definition of an answer. I've added Qs and As to assist in understanding. Obviously answering questions in great detail would make Lincs a terrible politician.
