Remember when life was whatever is “capable of undergoing Darwinian evolution”?
In “Vocabulary of Definitions of Life Suggests a Definition” (Journal of Biomolecular Structure and Dynamics, October 2011), we learn that there are 123 definitions of life currently on the table, and a new one is proposed:
Life is self-reproduction with variations.
-Edward N. Trifonov. Vocabulary of Definitions of Life Suggests a Definition. J. Biomol Struct Dyn 29(2) 259-266 (2011).
Trifonov uses “semantic voting” (which features are mentioned most often) to arrive at this term. But note that “variations” may or may not mean Darwinian evolution, as understood today. It could obviously include other sources of change. Article here, free.
