Study shows elephants might call each other by name

和人类一样，非洲大象也会用“名字”呼唤同伴

Over the years, researchers who study elephants have noticed an intriguing phenomenon. Sometimes when an elephant makes a vocalization to a group of other elephants, all of them respond. But sometimes when that same elephant makes a similar call to the group, only a single individual responds. Could it be that elephants address each other by the equivalent of a name? A new study involving wild African savannah elephants in Kenya lends support to this idea. The researchers analyzed vocalizations - mostly rumbles generated by elephants using their vocal cords, similar to how people speak - made by more than 100 elephants.

多年来，研究大象的研究人员注意到一个有趣的现象。有时，当一头大象向一群大象发出声音时，所有的大象都会回应。但有时，当同一头大象向群体发出类似的叫声时，只有个别大象做出回应。

难道大象之间有类似于名字的称呼方式吗？一项涉及肯尼亚野生非洲草原象的新研究支持了这一观点。
