  • Not a dumb question. I think it’s because the Occipital lobe is an evolutionary old part of the brain. It’s right on top of the brain stem the oldest part.

    The newer parts developed between the eyes and the older parts of the brain. Pushing the eyes forward. That’s my understanding but I might be wrong.

    Hopefully if I am wrong someone jumps in and provides a correction.



  • Cephalopod precursors evolved eyes and then brains developed from the eye so their eye is structured correctly.

    Vertebrate precursors evolved the brian first and the eye evolved out the brain as a sensory stub. So it’s upside down and inside out like in picture.

    The nerve cluster goes through the back of the eye splits and folds back to end in light receptors. Light hase to go through the nerves before hitting the sensor.

    There is even a reflective layer after the sensors that gives the sensors a second chance at picking up the light. This is what causes the red eye or green eye you sometimes see in flash photography.

    It would require a genetic rebuild to fix this and the intermediate steps evolution usually use would be so disadvantageous they are selected against. So the right combo of mutations to give us a working octopus eye is VERY unlikely to happen.








  • I think the important bits are easy to pickup in context. There is a war and it’s not going well. Sisko is trying to bring a powerful neutral party into the war and is willing to do very questionable things to do it.

    As a Star Trek fan I had given up on DS9 during the original airing of the first season. Latter I caught Pale Moonlight by chance and it impressed me enough to watch some more. Then I went back and watched all the earlier stuff. Now it’s my favorite Star Trek.

    When I first saw it I knew Star Trek quit well but had no idea what was going on in DS9 and had no trouble following the story.
