New Study Finds Elephants May Have Names for Each Other

For years, scientists have observed elephants' high levels of intelligence when it comes to herd activity. A new potentially groundbreaking study shows just how smart they might actually be. 

The research, published in the Nature Ecology & Evolution journal, examined African elephants' responses to the sounds they make for each other and whether they mirror similar behaviors observed in dolphins and parakeets. In those species, however, the animals mimic each others' calls as a way of getting each other's attention.
