| Quote | Molecular Intelligence
Molecular intelligence (a living thing, life) is emergent from naturally occurring machine-like molecules which together build and maintain cells like we together build and maintain cities. This form of intelligence is sustained by a “replication cycle” that keeps it going through time. Biologically, our thought cycles exist as a brain wave/cycle rhythm but (where physics willing) the system would still work as well by replicating itself (and stored memories) on a regular cycle, as does molecular intelligence. If our brain worked this way then it would replicate/replace itself upon every new thought we have, could this way sustain itself nearly forever. Without cellular intelligence (discussed in next section) to add moment to moment awareness molecular intelligence is at the mercy of the environment, has no way to efficiently forage for food, but they still soon enough can control the planet’s surface/atmospheric chemistry.
Chromosomal subsystems may be separately modeled. The flowchart becomes:
Since cells of multicellular organisms can reconfigure even eliminate parts of their genome in order to “differentiate” into many cell types only our germ cells (which produce egg/sperm) would be fully representative of the memory contents of a molecular intelligence system. With all of the memory cycles before the one that made us is included, our molecular intelligence is currently estimated to be over 3.4 billion years old.

Complex forms of molecular intelligence have sensory receptors on their surface membrane for different morphogenetic proteins (substance that evokes differentiation). Interaction of the protein with the receptor initiates a cascade of events that eventually turns on some genes and turns off others, aiding differentiation of the cell into brain, muscle and other unique cells. Successful actions to take in response to environmental conditions are recalled from its RNA/DNA memory. New memories can be formed as in the classic example of the origin of nylonase6 whereby a successful response to environmental chemistry conditions is the result of a good guess that leads to a new action to be taken.
At the molecular intelligence level, good guesses are taken using mechanisms such as crossover exchange, chromosome fusion/fission, duplications, deletions and transpositions (jumping genes) whereby a coded region of DNA data physically moves to another location to effectively change its address location. Information shared by conjugation may possibly include good guesses which are incorporated into its genome. Somatic hypermutation occurs when immune cells are fighting a losing battle with germs. The cell then responds by searching for a solution to the problem by rapidly taking good guesses. This produces new defensive molecules which become attached to their outside, to help grab onto an invader so it can be destroyed.
Although a random guess can at times be better than no guess at all, uncontrolled random change (random mutation) in DNA coding is normally damaging. These are caused by (among other things) x-rays and gamma rays, UV light, smoke and chemical agents. Molecular intelligence systems normally use error correction mechanisms to prevent “random chance” memory changes from occurring. To qualify as a random guess the molecular intelligence system must itself produce them. An exception is where random change/mutation is the only available guess mechanism, which may have been all that existed at the dawn of life, to produce the very first living/intelligent things.
Without some form of good-guess genetic recombination the learning rate of the system would be very low. Offspring would normally be clones of their parents. Therefore a part of the cell cycle often has crossover exchange where entire regions of chromosomes are safely swapped, to produce a new individual response to the environment that should work as well or better. This is a good guess because the molecular intelligence is starting with what it has already learned then tries something new based upon that coded knowledge. This is not randomly mixing coding regions in an uncontrolled genetic scrambling which can easily be fatal.
Regardless of population size a molecular intelligence “gene pool” still relies on single individuals to come up with unique solutions to problems such as digesting nylon, antibiotic resistance and differentiation into new cell morphologies. A gene pool is the combined memory of a "collective intelligence" or more specifically "molecular collective intelligence". By using conjugation to share information, a colony of bacteria (or other cells) can be considered to be a single multicellular organism. |

The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection.
