As time went by Caleb
would have gradually added more enzymes and functional components,
by developing new genetic chains, and then transcribing them into
useful proteins.
Eventually Caleb would have evolved into
the best possible Caleb, which would have contained a selection of
enzymes that created all of its own raw materials.
Meet Cassius
This particular self-sufficient organism
could have included as few as fourteen components. It would have
needed at least seven aromatic chains (or seven genes, if you want
to start calling them that):
- A Sofia to code for Freds.
- A Sorrel to code for Roscoes.
- A Serena to code for Nathaniels.
- Two chains to code for enzymes that would
synthesize the two amino
acids used in Fred, Roscoe,
Nathaniel and the catalytic proteins.
- Two chains to code for enzymes that would
synthesize the two chain
molecules used in Sofia,
Sorrel, Serena and the chains coding for catalysts.
A self-sufficient
Caleb would also
contain at least seven proteins:
- A Fred, so protein synthesis could start
immediately.
- A Roscoe, so gene replication could start
immediately.
- One or more Nathaniels to hold everything
together.
- Two proteins to synthesize the amino acids
used in Fred, Roscoe, Nathaniel
and the other proteins.
- Two proteins to synthesize the chain molecules
used in Sofia, Sorrel, Sofia
and the other chains.
The result would be truly a mighty organism,
an Über-Caleb that could cruise into any puddle in the world,
fill it up with its own raw materials, and start replicating.
This new combination of molecules so much
more advanced than Caleb that we'll
evolve into a new name, and call it a Cassius (short for Combined And Self SufficIent Über-molecular
System).
This snaky molecular complex is all it takes
to invade any puddle in the world, and create
more of itself.
