Last night was a long one. I started out driving at 2:30 pm. I picked up the limousine and headed to the funeral home to pick up the owner and a few of his friends. Our local sports teams are doing quite well lately and they got their hands on some Monday night football tickets to see the Detroit Lions take on the Chicago Bears. They started their night out catching the Detroit Tiger's game on a big screen at a local bar in Detroit. So they really did see Lions and Tiger and Bears!
For the sports enthusiast, the Tigers lost and the Lions won.
By the time I was heading home, it was 2:30am. Of course it was dark and because of our unseasonably warm October days, it was foggy as the night chill set in. As I drove along with the fog lights illuminating the pavement in front of my car and the headlights off, I'd catch the occasional glimpse of a dear or other animal along the side of the road, grazing on the long grass in the ditches. You could see the eyes of the animals reflecting the lights back at me. This made me think first that evolution has really helped us to be able to see them as we drive and avoid the hazards of them wondering out in to the road.
But then I thought, I'm sure that their eyes did this before there were cars. And I started to think about what actually makes their eyes do that. You can see it in almost all animals.
Then I remembered back to the morning before as I made my way home from my other night job and the children were walking to school in the fog. Their eyes don't glow!
Why do you suppose that we humans don't have the same thing in our eyes that make them glow in the dark as our mammal counterparts.
