much better, except the patterns are not truely random either, remember the different shape snowflakes, a certain shape is selected for in a snowfall, the flakes are a "kind" in each fall, the shape of the individual flake is dictated by the conditions in which the flake forms.
which dictates the kind of flake that forms.
note, I believe that each snowflake is complete, a finished form.
so the difference in kinds is not merely different stages in growth, but rather fundamental differences in structure.
so, the randomness only operates WITHIN each kind, specific ranges of shapes are selected for, while incorrect shapes, kinds, are selected against.
within the selected for kind of shapes randomness gets to go nuts and try everything that might work.
and then waters suckyness manifests and the flake falls to the ground.
{note that selection doesn't stop there, some flakes get to grow up to be a glacier, others don't.}
carbon, on the other hand gets to hook up with OTHER atoms and form REALLY cool complicated shapes, which are selected for coolness.

just now.
yeah, I like how it can dissolve stuff and then evaporate and leave the gross flesh behind, becoming pure again.
even though it and trillions of its brothers just drowned a planet.

no, wonderful example.
water is so very complicated and cool while being nowhere as complicated as carbon, which DOES form the simple but beautiful DNA molecule.
more beauty with more complexity, which is selected for.

did
you read the article ?
in the liquid form water falls into a shape with high surface tension, and so when not acted on by outside force forms itself into a sphere.
{ I wonder how big a sphere of water it would take for its gravity to keep its shape {in freefall} harder than the surface tension would ? }
a CO2 molecule falls into water, a couple of hydrogen atoms grab the oxygen and the Carbon atom is FREE !!!
to go bumping into all sorts of other atoms dissolved into the water, with energetic radiation falling from the sky to keep things moving.
and its unions being selected for coolness.
