We know that disparate chimp kin split by large areas have different behaviors and finish , but what about those dear to one another ? It appears that neighboring chimp do roleplay differently in one key way : how they crack open nuts .
Three group of chimpanzee survive in Taï National Park , Côte d’Ivoire , all of are adjacent and come in contact lens with one another . Yet all three have dissimilar approach to open up the local Coula testis . The groups express their taste for both fabric ( wood or Edward Durell Stone ) and size . No one eccentric is universally more effective or easier to find , and all the groups have access to the same materials and same plant , toss a purely practical explanation .
These three groups of chimpanzee are not genetically distinct , either — some individuals moved from group to group , and in those cases adopt the neighborhood style . This is differing chimpanzee cultivation on a much more fine grained level than ever noted before , one not define by large geographical or inherited tear .
So , there ’s a chimpanzee version of the galling local homeowners affiliation which decide what colour you’re able to paint your house , except these guys choose how you prepare food .
