> However being so small, there is a trade-off in that Portia can only focus its eyes on a tiny spot. It has to build up a picture of the world by scanning almost pixel by pixel across the visual scene. This is fascinating. I wonder if the limited visual focus plays a similar role as consciousness in higher animals. It enables the brain to work on larger problems by focusing on one small Problem at a time. (Of course, consciousness is more than that...)
