Many years ago I worked with intraocular lenses for cataract patients. One of our scientists in a previous life had done work trying to figure out how eyes encoded information.
They were very surprised to discover that the images weren't just digital or analog in the brain but the signals were frequency modulated somehow. They were stopped there -- they could not even begin to decode the information.

I wish I weren't so pessimistic but I'm seriously afraid that there are many levels of complexity that we haven't even begun to imagine -- that evolved dynamically over eons.
