The cognitive abilities of Neanderthals are debated, but a raven os fragment institute at the Zaskalnaya VI (ZSK) site inwards Crimea features ii notches that may convey been made past times Neanderthals intentionally to display a visually consistent pattern, according to a report past times Ana Majkic at the Universite de Bordeaux together with colleagues, published inwards the opened upward access journal, PLOS ONE on March 29, 2017.
Majkic together with colleagues conducted a mixed-methods report to assess whether the ii extra notches on the ZSK raven os were made past times Neanderthals amongst the intention of making the end serial of notches look to move evenly spaced. First, researchers conducted a multi-phase experiment where recruited volunteers were asked to occupation evenly spaced notches inwards domestic turkey bones, which are like inwards size to the ZSK raven bone. Morphometric analyses break that the equal spacing of the experimental notches was comparable to the spacing of notches inwards the ZSK raven bone, fifty-fifty when adjusted for errors inwards human perception. Archeological specimens featuring aligned notches from unlike sites were too analyzed together with compared amongst the ZSK raven os specimen.
