一项发表在《心理学前沿》杂志上的新研究揭示了黑猩猩如何将工具使用行为代际传递的机制。1来自巴塞罗那大学和塞内加尔简·古道尔研究所的研究人员发现，成年黑猩猩会有意展示行为示范，随后将工具交给幼体进行模仿，其中母兽在这一教学过程中扮演主要角色。1共同作者安德鲁·桑切斯-梅吉亚表示，"工具转移似乎是一种教学形式，与观察和监督实践一起"进行。1
黑猩猩的工具使用能力早已为科学界所知。1查尔斯·达尔文在1871年就观察到黑猩猩用石头敲碎坚果的行为。11960年，简·古道尔记录了黑猩猩大卫·格雷比尔德弯曲树枝、剥去叶子，用来从蛀虫窝中取食白蚁的情景。1这项最新研究进一步表明，这些技能通过社会学习从成年个体传递给后代。1
A new study published in Frontiers in Psychology reveals that chimpanzees transmit tool-use behaviors to their offspring through social learning, with adult individuals deliberately demonstrating techniques and then handing tools to young chimps to practice the same actions 1. Research co-author Andreu Sánchez-Megías from the University of Barcelona and the Jane Goodall Institute in Senegal found that mothers serve as the primary models and instructors in this teaching process 1.
The researchers characterized tool transfer as a form of teaching, occurring alongside observation and supervised practice 1. This discovery builds on historical observations dating back over a century: Jane Goodall documented in 1960 how a chimpanzee named David Greybeard bent branches, stripped their leaves, and used them to extract termites from mounds 1, while Charles Darwin noted in 1871 that chimpanzees used stones to crack nuts 1.
