Since you are asking for examples of complex things build themselves from raw unorganized elements, here are a couple of examples:
-Snowflakes and other crystals
-Chemistry in general
-Sand on a beach being ordered by size due to the action of the waves.
Crystalline particles are not "raw unorganized elements" they have a molecular structure that
requires that they stack up into crystals - check into a little chemistry, will ya? Chemistry
relies on the predictability of elements based on their atomic structure, hence the periodic chart. The processes needed for chemical reactions are very organized & predictable if the variables are known.
As for sand on a beach, it is neither raw (sand particles have known characteristics & are therefore predictable - they will not get up, form into a marionette and do polka for us), nor is the "ordering" unorganized (the size and density of the particles is what sorts them like change in a change counter & wind is directed by pressure & temperature variations, obstructions to flow, and gravity, among other things - predictable & reproducible if all factors are known).
Any other examples? None of these examples end in a brand, spankin' new life form either do they?
Evolutionary algorithms are also used quite a bit in engineering today, so most engineers will be familiar with these concepts.
I guess old engineer that I am, I've not been exposed to these algorithms. Are you talking about artificial life forms - computer programs that "learn?" These would be examples of one species of programs "evolving" into a new species of program? Not really, just new ways of solving problems - kind of like brainstorming with a sleepless brain.
There are more examples to be had, but any of these are an example of complexity arising from simple processes.
You are going to have to come up with something better than these examples. Not one of them is viable.
