Vestigial garages

In America, they say, garages are so big that people store cars in them! Here in England, of course, that hasn’t been the pattern for years. But though our garages are too small for cars, they’re great for tools and workbenches, making perfect male caves. My father-in-law wouldn’t know what to do without his.

We puzzle how the eye could have evolved by natural selection. What use was the first step along the evolutionary path to an eye? You just have to remember that evolution took twists and turns on its way to the present, and if your cave seems too good to be true, it may have originally evolved for quite another purpose.
