Innovative problem solving by wild spotted hyenas

Abstract: Innovative animals are those able to solve novel problems or invent novel solutions to existing problems. Despite the important ecological and evolutionary consequences of innovation, we still know very little about the traits that vary among individuals within a species to make them more or less innovative. Here we examine innovative problem solving by spotted hyenas (Crocuta crocuta) in their natural habitat, and demonstrate for the first time in a non-human animal that those individuals exhibiting a greater… Show more

“…The social intelligence hypothesis proposes that increased social complexity (frequently indexed by social group size) was the major selective pressure in primate cognitive evolution (6,44,48,50,87,115,120,(125)(126)(127)(128)(129)(130)(131)(132)(133)(134)(135)(136)(137)(138)(139)(140)(141). This hypothesis is supported by studies showing a positive correlation between a species' typical group size and the neocortex ratio (80, 81, 85-87, 129, 142-145), cognitive differences between closely related species with different group sizes (130,137,146,147), and evidence for cognitive convergence between highly social species (26,31,(148)(149)(150). The foraging hypothesis posits that dietary complexity, indexed by field reports of dietary breadth and reliance on fruit (a spatiotemporally distributed resource), was the primary driver of primate cognitive evolution (151)(152)(153)(154).…”

“…Comparing dog populations with 524 varying levels of experience with humans (such as pet dogs and free-ranging dogs) may help to better 525 understand whether dogs' reduced persistence could be a result of humans inhibiting their 526 interactiveness with objects. 527 22 In line with previous studies (Morand-Ferron et al, 2011;Benson-Amram & Holekamp, 2012; 528 Huebner & Fichtel, 2015;Borrego & Gaines, 2016), we found motor diversity to be positively linked 529 to persistence in both tasks, in both dogs and wolves. Motor diversity and behavioural flexibility is 530 important during foraging.…”

“…For example, if neophilia declines with age, young individuals might display more innovations in novel contexts and adults more innovations involving novel behavioural sequences in familiar contexts [26,27]. Without distinguishing between different forms of innovations, analyses might reveal no evidence of a relation between neophilia and innovation, because low neophilia adults are just as innovative overall as high neophilia juveniles.…”

“…For example, catching insects under a street light rather than under moonlight should only depend upon the motivation to approach a novel context (the unnatural light spectrum of a street lamp). By contrast, producing novel behaviours in old contexts might draw more heavily upon the tendency or ability to vary ones motor actions [26,58,70,71], and, as argued by Tebbich et al [60], morphological features that increase the diversity of ways in which an organism can interact with its environment. Some species, such as keas and Goffin cockatoos, equipped with a high level of spontaneous attraction to novelty and multiple, exceedingly manipulative appendages (beak and feet), might excel at both forms of innovation outlined above and emerge as the most frequent innovators.…”
