“If an individual monkey had not started to wash sweet potatoes by the time he was an adult, he was unlikely to learn it later, regardless of how widespread it became among the younger members of the troop.”

“She taught this trick to her mother. Her playmates also learned this new way from her and they taught their mothers.Before the eyes of the scientists, this cultural innovation was gradually picked up by various monkeys, and by 1958 all of the young monkeys on the island had learned to wash sandy sweet potatoes to make them more palatable.”

就是说， 那些大猴子们其实没有学会洗番薯？ 为什么？ 成年猴子的学习能力还很强的。

另外，最初Imo洗番薯是自发行为还是模仿？ 比如人洗东西吃的时候被它看到了？

猴子很聪明的，以前我训猴子时，经常有人提醒我，小心反过来被猴子控制。
