I'm kind of perplexed that no one here, of all places, should have an answer â€” even an ambiguous one. I know, I'm into the boring science stuff
still I appreciate the thoughts you've offered so far.
I offer a new distinction, submitted for your approval or criticism, with the root á½ Î²Î¹ÏŒÏ‚:
BIOTIC = living, once living; organic.
Biota are the living part of a geologic system while abiota are the inert rocks.
BIOGENIC = created by life, formed as a result of life.
For example, my research project and undergraduate thesis focuses on biogenic nitrogen as a potential tracer for the ancient Martian biosphere.
BIOGENETIC = associated with life, typical of life, coevolved with life, indicative of life.
In exoplanetology, if we discover a planet with a signature of O2, that would suggest a biogenetic atmosphere.
What do you think?
