Smarter secrets Monkeytalk: Inside the worlds and minds of primates by Julia Fischer, University of Chicago Press
JULIA FISCHER is a leading primatologist best known to the public for her work with a dog called Rico that she spotted on a German TV show. Rico, it was claimed, could remember the names of some 70 toys and fetch them on command. Despite Fischer’s initial scepticism, her experiments showed that the Border collie’s talents were even greater than claimed. The story of Rico and the press frenzy that followed its publication in Science is retold in Fischer’s new book Monkeytalk. It is a delight, especially when we learn that another Border collie has learned the names of 1022 toys. But to Fischer, head of the cognitive ethology department at the University of Göttingen, Germany, the story has a deeper significance. A dog’s range of barks, growls and whines is restricted, as are the vocalisations of monkeys: the vocal organs of these animals are simply not wired up to the bits of the brain that could provide the fine motor control needed. That means the range of things an animal can communicate about vocally may tell us little about what it can think about and act upon. To get “inside the worlds and minds of primates”, as the book’s sub-title claims, requires us to put aside language-biased To understand our origins we must explore our close relatives 46 | NewScientist | 28 January 2017

This Fischer’s book is a wonderful, shocking breach of inter-family short guide to the ingenious and etiquette excited the listeners patient work that is giving us and showed how well they knew deeper insights into primate individuals and their place in psychology. society.

The bachelor’s head spun: In one, a threat call from a lowif the male and his consort were ranking female chacma baboon apart it might mean a break-up – was followed by the screams of and an opportunity. Moments a higher-ranking female from a later he “ambles nonchalantly
towards ‘her’ ”, Fischer writes. These and many other experiments show that monkeys possess profound social intelligence and can solve problems in their own environment. But as we move towards more abstract intelligence and language, a gap opens up between them and us. Fischer adroitly explores the big questions now being asked about primate minds. Can they understand the intentions of others? Are they able to “time travel” and plan for the future? How much can they learn by watching others? Are they capable of metacognition, of knowing what it is that they know? Monkeytalk has its faults: it starts like a textbook and it takes a little time before you discover its unusual mix of science and insight, interspersed with funny anecdotes from African field work, including how to dress for “survival in the bureaucratic jungle”. Pink pumps, a plastic handbag, lots of rhinestones and glittery appliqué were all needed for Fischer to meet local expectations of what a lady looked like – and obtain a vehicle permit. The book ends on a serious note, though. The only way we will really understand our own origins is to explore the minds of other primate species along with the bewildering differences in the societies they live in, their ecology, neurobiology and genetics. But primate populations are being destroyed so fast that our close relatives may vanish from the wild before we can find out what made us human. n Alun Anderson is a consultant for New Scientist
