- So what if it isn't carrying genetic information? Self-replication is
- self-replication. Evolution will favor more complex forms, and eventually
- it won't be 'trivial' anymore. BTW, what is the definition of 'trivial'
- in this context? And no, evolution does not require DNA. In this context
- (usually called chemical evolution) it is just the process by which those
- structures that replicate (whether 'trivially' or not) come to dominate.

-
- By what standards are you deciding that it 'doesn't count'? If it can be
- demonstrated (as I think it has, both in my own studies and in the
- synopses offered here of late) that life processes can arise on their
- own, without the infamous hidden watchmaker, or without the improbable
- 'protien of the Ninth Configuration', then what exactly, does 'not
- counting' mean? That we aren't here? Ps- it's been mentioned already,
- but RNA doesn't need genetic material, because it IS genetic material.
- If we could talk to a piece of DNA, it might say that we existed for IT.
-
- Aaaaand, as long as you have such a great handle on the defintion of life...
-
- 1) Are viruses alive? They reproduce non-trivially (by what I can get
- of your defintion from context)
-
- 2) If humans built self-sufficient space colonies, would it mean that
- Gaia (the entire biosphere) had reproduced? Evolved?
-
- 3) Is human culture, as a whole, an organism? It feeds, makes wastes,
- evolves, etc...
