When people want to direct the attention of others, they naturally do so by pointing, starting from a very young age. Now, researchers reporting in Current Biology, a Cell Press publication, on October 10 have shown that elephants spontaneously get the gist of human pointing and can use it as a cue for finding food. That's all the more impressive given that many great apes fail to understand pointing when it's done for them by human caretakers, the researchers say.
When I heard that headline a while ago I facepalmed. How much money was wasted figuring that out? "Hey, I wrote up a hypothesis and tested it. I point over there and the elephant looks! Now I'll write a journal article and get published" So. Stupid. Even my cat knows when I am pointing at something, did anyone else not think an elephant wouldn't? I'm going to do an experiment of my own. If I don't water my lawn it seems to die each time. I guess lawns know when they aren't getting water. SMH.
