until it passes a threshhod of complexity. The nucleic acids could not
replicate until they united into strings of complex code pairs; when they
did, they became alive.
DNA and protein are far too complex to have existed at the beginning of
life. Check out *Seven Clues to the Origin of Life,* by A. G. Cairns-Smith.
Most likely, the original organisms were based on clay crystals rather than
nucleic acids. Later, when the framework was in place, the clay was
gradually replaced by the more efficient nucleic acids.
You seem to be suggesting a vitalistic conception of life based around
complexity. The "elan vital" that animates living things is their
complexity. Life is a product of molecular complexity, while consciousness
is a product of neural complexity. If this were true, machines would spring
to life once we've sufficiently complexified them.
I'm afraid it's not that simple.
