What Do Animals See in the Mirror?
There was a distinctly unsettling paper[1] a couple of years ago which found evidence that ants could recognize themselves in a mirror, which is really not a result you'd expect from something (ab)used as a "sentience test". I've seen very little followup on this; does anyone know how it's been received?[1] http://www.journalofscience.net/File_Folder/521-532(jos).pdf
