A very long time ago (1969) I wrote a college paper about color
vision in non-primate mammals. It was pretty short! It seemed to
me at the time that the behavioral techniques for "asking" the
animals what they could see weren't adequate to the task. I'm glad
that the topic is being researched more extensively now.
