Chimps and orangutang plan for the future just like us .
They are capable of exercising self - control to postpone gratification and to think next consequence via " mental clock time travel , " according to novel research from Lund University Cognitive Science in Sweden .
Chimpanzees in the Kibale National Park in Uganda eat dirt for its health benefits.
The acquirement of future provision was usually call back to be exclusive to humans , although some study of apes and crows have challenge this idea , say researcher Mathias and Helena Osvath . Now , for the first metre , there is " conclusive evidence of advance planning capacities innon - human species , " they say .
The Osvaths see this out by prove two female Pan troglodytes ( Pan caveman ) and one manly orangutan ( Pongo abelii ) from the Lund University Primate Research Station at the Furuvik Zoo a hosiery and how to apply it to pull fruit soup .
The research worker then entice the apes ( apes are a group that includes chimp , gorilla , orangutan and homo ) with their best-loved fruit alongside the hosiery to quiz their power to suppress the choice of the immediate reward ( favorite fruit ) in favor of a tool ( the hose ) that would lead to a larger reward about an hour later ( the fruit soup ) .
The imitator select the hose more frequently than their favorite fruit , suggesting they are able-bodied to make selection in favor of next needs even when they contend directly with an immediate reinforcement .
A 2nd experiment involved offeringthe apesnew dick — a functional one that would work like the hose and two " distractor objects , " such as a profane charge card car , a small teddy bear or a discarded radiocarpal joint spotter .
The apes consciously chose the newfangled functional tool more often and later used it suitably , demonstrating they pick out the tool ground on what it could do for them down the line .
The apes were likely pre - experience a succeeding event , that is visualizing the use of the novel dick to extract the fruit soup , the Osvaths say .
" This suggest that the advanced mental capacities utilize in human next preparation are share by phylogenetically more ancient coinage than antecedently believed , " the authors write , and " that capacities central to humans evolved much originally than previously conceive . "
The researchers suggest conducting standardised experiments in the future on small child and on Hylobates lar , the closest congener to the great apes .
The results are detailed online this hebdomad in the journalAnimal Cognition . The research was fund by Lunds University and the European Union ’s SEDSU project , " Stages in the evolution and evolution of polarity exercise . "
