Natures wonders: zebrafish 360 degree vision (Introduction)

DAVID’s comment: this is a protective vision system that is likely to have been invented by design when the zebrafish first appeared in evolution. More design.

dhw: Thank you for another wonderful wonder. Just in case there are any readers out there sharing my delight at all these wonders, the word “design” need not be taken to mean divine preprogramming or dabbling. Even though I share David’s scepticism as regards the super-efficiency of random mutations, I propose that these variations are intelligently designed by the cell communities of the organisms themselves, in response to the needs or opportunities arising out of environmental conditions. I leave open the question of how cells first acquired this adaptive and innovative intelligence.

If zebrafish needed this type of vision to survive (Darwin style) why shouldn't they have been designed this way when they first appeared?
