Point taken, but it still has no bearing on the fact that Darwin does not deal with origins of life which you said, 'does not sound right'.Quote from Ricter:
Lol, I don't know commodity traders, I'll take your word for that!
I'm saying there is no bright line. It's easy to see the difference between widely separated entities like your examples, but not easy between closely placed entities right at the "cusp" of life. Last I heard, but this is years old, there is still no agreement on whether viruses are truly alive. But I do think prions are not considered living.
If you want to deal with origin of species, evolutionary development of species, taxonomic group of organisms, or in other words, all known living things, then Darwin's evolution works brilliantly.
Everything else including the origin of life itself is nothing to do with that.
I'd suggest the line is made bright when not wearing creator designed sun shades .
