But keep in mind these were Duke students...
Add this to the growing list of reasons humans aren't so special, after all: Monkeys can subtract.
The discovery marks the first time a nonhuman species has been seen having "widespread success" with subtraction, scientists announced last Thursday.
Rhesus macaques placed in front of touch screens in a Duke University laboratory were able to subtract dots—not by counting them individually but by using a more instantaneous ability researchers call number sense.
[...] In fact, college students used as controls in the study had the same success rate as the macaques—each group choosing the correct answer in as little as a second, Cantlon said at an American Association for the Advancement of Science meeting in Chicago.
