THE BRAIN IS A MIRROR OF EVOLUTION

‘I think; therefore I am’&EMDASH;Descartes famous quotation can be assigned a new meaning in biodevelopment, the better term for 'evolution'. For what is happening constantly in our brain is a copy of the process. The brain constantly processes and evaluates data coming in from the external and internal environment, it eliminates what is unnecessary and illogical, it tries many possibilities, even outlandish ones in dreams, and arrives at its conclusions. A vast sifting process is going on constantly in order to arrive at the conclusions best-fitted to the circumstances, present and future.

The difference is that our thinking can be distorted by bad upbringing, both external and internal, but the process of evolution is far more sensible (spontaneous abortion and unsurvivable disease weed out the failures).

Just as the organism alters its behaviour to benefit it in changing circumstances, so too does that which makes up the organism--all the way down to biomolecular level.

CELLS THINK - LETTER TO SCIENCE

A copy of a letter sent in early 2011 to Science magazine, the publication of the American Association for the Advancement of Science (it was not published):

An article headed Molecular Dynamic Simulations on page 1607 of volume 330 of Science dated 17 December 2010 said, 'a simple protein with 100 amino acids can fold 3^198 different ways... Proteins sort through all these possibilities in milliseconds or less.' And your editorial on page 1724 of volume 330 dated 24 December 2010 said, 'An animal cell behaves as though it contains a tiny computer, assessing the many signals it receives... But the crucial next challenge... is to decipher exactly how the elaborate networks of signalling molecules that exist inside a cell enable it to make its crucial decisions--a process analogous to cell "thinking".'

Without the quotation marks round 'thinking' those two excerpts together express a fundamental truth: intelligence drives life. Cellular intelligence is driven by molecular intelligence; organic intelligence is driven by cellular intelligence.

It is not just neurons that think and together make a vastly higher capability. All cells do. The entire body is brain, because every cell is intelligent (and because the purpose of the body is to serve the brain). I think, therefore I am what I am; I am what I am, therefore I think.

The cell does *not* behave as if it contains a tiny computer. No, it is a vastly powerful network of tiny computers--the myriad of molecules in it. It is a World-Wide Web of them, and the body is a Galactic Hyper-Web of World-Wide Webs.

But the driver of life is vastly more than just the driver of the life and development of the organism. Via genetic inheritance the intelligent processing continues through the generations, and thus the development of that life-form continues across the aeons.

It is not 'natural selection' and 'random mutations.' It is intelligent selection and intelligent changes.

Both disease and evolutionary dead-ends are therefore the same thing, on different time-scales: processing errors (albeit sometimes ones that did not produce enough flexibility to accommodate environmental changes).
