So, Lettvin, Maturana et al make it clear that the frog’s eye does not tell the frog’s brain what exists in the world around the frog, the frog’s eye tells the frog’s brain about where it thinks food exists.  Darwin’s natural selection process has helped the frog develop its senses and neurological system in ways that have produced a frog who is not capable of seeing the world, but is tuned to seeing food before it.

Think about that a bit and ask yourself how natural selection has affected what a human being actually sees?   What does a human being’s eye tell a human being’s brain?

Can we sense slow-moving threats to our existence or do we rely on a “nervous” system that has developed to help us avoid being eaten by quick-moving threats?  Can we evolve in our ability to process information and make sensible long-term decisions that are truly good for us and our offspring or are we doomed to the distractibility available through things that go bump in the night, terrorists lurking in the shadows?
