I wasn't referring to anyone's expertise in the field, but to humanity's understanding of a five billion year old intelligent system. What we've done so far is impressive, but we've really only scratched the surface. It's a bit early to claim superiority.

We actually do know something about why the genetic code might have only four codons, and other aspects of its structure. It gets into combinatorics and search.
