摘要

Townrow and Krupenye (PNAS, 122(6), Article e2412450122, 2025) found that bonobos understand the mental states of others and can attribute ignorance to a social partner. In an elegantly simple design, the authors found bonobos to communicate more often, and more quickly, when a social partner is ignorant, rather than knowledgeable, of the location of a hidden food item.
