Considering the variety of animals that seem to show this behavior, isn't it possible that mammals, specifically humans, are "encoded" with that same random search pattern? I'm not sure how you'd test for it though.

I instantly thought about eye tracking experiments, in which we see lots of small movements around an area, then big jumps across the screen. I guess others have thought about it too.

I'm intrigued.

That is fascinating. Thanks for that.
