yawning and grooming, is contagious in chimps.<\/p>\n\n\n\n<p>Onishi, Yamamoto and colleagues spent more than 600 hours studying 20 captive chimps living in a wildlife sanctuary \u2014 and observed them peeing more than 1,300 times.<\/p>\n\n\n\n<p>An analysis of those observations revealed that chimps were likely to pee together, and if a chimp was near an individual that was urinating, <a href=\"https:\/\/www.cell.com\/current-biology\/fulltext\/S0960-9822(24)01594-X\" target=\"_blank\" rel=\"noopener\">it too was more likely to start peeing <\/a>\u2014 suggesting that the behavior is contagious, the researchers report January 20 in <em>Current Biology.<\/em><\/p>\n\n\n\n<p>Unexpectedly, the team also found that this copycat behavior was not influenced by social closeness, as in the case of grooming and yawning. Instead, the researchers found that rank played a role. Low-ranking individuals were more likely than others to start peeing if a chimp nearby did. \u201cThis was an unexpected and fascinating result,\u201d Onishi says. \u201cIt opens up multiple possibilities for interpretation.\u201d<\/p>\n\n\n\n<p>High-ranking individuals might influence the urination of others, Onishi says. Or perhaps low-ranking chimps \u201care more likely to notice and respond to the behaviors of others, including urination,\u201d she says, given \u201ctheir heightened vigilance in social settings.\u201d<\/p>\n\n\n\n<p>Further research could show if the phenomenon has any viable function, says Zanna Clay, a psychologist at Durham University in England who wasn\u2019t involved in the research but who has studied the <a href=\"https:\/\/www.sciencenews.org\/article\/adult-chimps-play-importance-chimpanzee\">contagious nature of chimp grooming and play<\/a>. \u201cIt\u2019s a promising and preliminary step,\u201d she says. \u201cBut I think \u2026 it\u2019d have to be investigated in more detail to really understand if it\u2019s something of relevance.\u201d<\/p>\n\n\n\n<p>Onishi and her colleagues next want to study other groups of chimpanzees, including wild chimps, to see \u201chow social factors like sex, familiarity, and age might influence contagious urination.\u201d And \u201cexpanding comparisons across species,\u201d for example, by studying bonobos, Onishi says, \u201ccould provide especially intriguing insights when compared to our findings in chimpanzees.\u201d<\/p>\n\n\n\n\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/chimpanzees-contagious-peeing\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>Hate waiting in line for the bathroom?
