It's close to but not quite like the Dr.Seuss book，where the elephant Horton hears something that others can't hear. McComb and colleagues went to Amboseli National Park in Kenya，where hundreds of wild elephants live among humans，sometimes coming in conflict over scarce water.The scientists used voice recordings of Maasai men，who on occasion kill elephants，and Kamba men，who are less of a threat to the elephants. As a result，the elephants reacted more defensively—retreating and gathering in a bunch—to the Maasai language recording because it was associated with the more threatening human tribe，said study co-author Graeme Shannon. They repeated the experiment with recordings of Maasai men and women.Since women almost never spear elephants，the animals reacted less defensively to the women's voices.The same thing happened when they substituted young boys' voices.“Making this kind of fine distinctions in human voice patterns is quite remarkable，” said Emory University animal cognition expert Frans de Waal，who was not part of the study. 1．Who were the people taking part in the study?
