A researcher at a Tokyo zoo has discovered that elephants have more than just good memories - they have the ability to carry out basic mathematical computations. We all understand the notion of a "legacy brain" being capable of simple memorization, recognition, and the ability to quickly analyze a situation and either fight or flee. But I don't think math skills have ever been part of that, er, equation. Although maybe it does make sense for animals that roam about in herds, since they would benefit from basic chaperone skills to keep the herd intact. They don't need a No Calf Left Behind law...they just use their brains!
