Remember that chimp you met at the zoo when you were a kid? Well, it turns out they might remember you too… In a groundbreaking new study, researchers have found that bonobos and chimpanzees can remember their friends, even after decades apart. Dr Laura Lewis and her team showed 26 apes pictures of other apes they’d never met and old pals. The apes spent longer looking at pics of their mates than the strangers – and the gold star goes to a 46yo bonobo named Louise, who recognised faces, even after spending 26 years apart… Dr Lewis reckons the results “represent some of the longest long-term memory ever found in nonhuman animals.” Wonder if Louise also remembers that old friend who never returned a favourite book, or is that just us projecting again?
