moss sponging by chmpanzees - is a phenomena observed by researchers - in which the distinction between<br /> - individual and - collective learning - is fuzzy - Sponging is a technique of wild chimpanzees - in which they use chewed up plant material - as a sponge to soak up water - One individual wild chimpanzee - named by the researchers as KW - picked up a discarded sponge used by another wild chimpanzee - which happened to have moss in it - and so developed a sponge for water specifically from moss - KW did not learn it socially from another chimpanzee - yet if it weren't for - the behavior of other chimpanzees in the group - cultural artefacts they left behind - niche construction that resulted to changes in the environment - the individual learning of KW would never have produced moss sponging
