n.(Boesch)人名;(英、德、西)伯施
So Tomasello´s Max Planck colleague primatologist Christophe Boesch looked for evidence of altruism in the wild.
所以,托马塞洛在麦克斯·普朗克的同事,灵长类动物学家克里斯托夫·伯施,就开始了在野外需找证据。
Boesch says altruism may not show up as often in captivity because captive animals don´t need to stick together to survive.
伯施说,利他主义行为在圈养环境下发生的并不那么频繁,因为圈养动物不需要只有抱成团才能生存下去。
