If You Want To See An Elephant Do Math

Then today is your lucky day.

For example, when researcher Naoko Irie-Sugimoto dropped three apples into one bucket and one apple into a second, then four more apples into the first and five into the second, Ashya correctly identified that the first bucket contained more apples and began munching on her tasty prize.

Ashya and her companions chose the correct bucket 74% of the time. “I even get confused when I’m dropping the bait,” Irie told New Scientist magazine.

The elephants’ counting abilities are far from unique. Chimps, salamanders and pigeons have shown numerical abilities in lab tests, but what is more impressive for the elephants is that their ability to distinguish between two figures does not get worse when those numbers are more similar.

The elephants that Irie-Sugimoto tested were as good at telling the difference between five and six as they were at distinguishing between five and one.

She presented her findings last week at the International Society for Behavioral Ecology’s annual meeting in Ithaca, New York.

It is not obvious why elephants should need this mathematical faculty in the wild. “It really is tough to figure out why [elephants] would need to count,” said Mya Thompson, an ecologist at Cornell University who studies elephants.
