Copying from Slashdot;
“A recent article in Journal of Biomolecular structure and Dynamics proposes to define life by semantic voting [Note: open-access article]: ‘The definitions of life are more than often in conflict with one another. Undeniably, however, most of them do have a point, one or another or several, and common sense suggests that, probably, one could arrive to a consensus, if only the authors, some two centuries apart from one another, could be brought together. One thing, however, can be done – short of voting in absentia – asking which terms in the definitions are the most frequent and, thus, perhaps, reflecting the most important points shared by many.’ The author arrives at a six-word definition, as explained here.”
Taking a look at that definition;
Life is autonomous self-reproduction with variations.
I see the key here as “variations“. Why do you think?
