Savage Rumbaugh


  • Kanzi and Mulika were for more able to understand spoken english words
  • Kanzi and mulika used lexigram with more ease and more spontaneously without training compared to Sherman and Austin


  • Pgymy Chimps exhibit symbolic and auditory perceptual skills that are significantly different to those of common chimpanzees. This is suprising as they are closely related
