RATS CAN TELL HUMAN LANGUAGES APART

A piece in New Scientist tells how rats showed they could distinguish between Dutch and Japanese. "Toro's team trained rats to recognise either Dutch or Japanese - by pressing a lever in response to a short sentence - and then exposed them to sentences they had not heard before, in both languages." Not to belabor the point, but I'm certain there are literally millions of human beings who would be unable to succeed at this task.
