Evolution Test

This test is based on a research about primate cognition by the Primate Research Institute of Kyoto University.* Chimpanzees, like Ai and Ayumu, have been trained to learn Arabic numerals (Levels 1-2); then, their eidetic memory was tested (Levels 3 to 6), giving astonishing results and proving better performances than humans'.Ayumu could easily score 608 on this test (i.e. Level 6, 7 numerals).Untrained humans can barely score 506 (i.e. Level 5, 5 numerals).It's noteworthy that children have shown better results than adults.Could this be improved by training?* which Simiotic is not affiliated to
