>>In the 1993 movie Jurassic Park, one human character tells another that a Tyrannosaurus rex can't see them if they don't move, even though the beast is right in front of them. Now, a scientist reports that T. rex had some of the best vision in animal history. This sensory prowess strengthens arguments for T. rex's role as predator instead of scavenger. <<
I thought that was due to how the brain interpretted what the eye sees as opposed to how good the eyesite is.
You know, how you can look at a bush and not see the bird in it until the bird moves. That is due to my brain, not my eye. Last I heard, it is believed that t-rex was not all that bright.
Oh, no, not true at all--TRex could, in fact, do long division. ;)
I think a cat's vision is like that. Some kind of feedback loop that makes their eyes turn and look towards movement.
