南部非洲的Chacma baboons 表现出相互争斗,揭示了灵长类动物嫉妒和竞争的演化根源。 Chacma baboons in southern Africa show sibling rivalry, revealing possible evolutionary roots of jealousy and competition in primates.

新的研究表明,以前被认为是人类独有的同族争斗也发生在南部非洲的Chacma baboons。 New research shows that sibling rivalry, previously believed to be unique to humans, also occurs in chacma baboons in southern Africa. 科学家观察到侵略、争夺食物和产妇注意力、兄弟姐妹之间的社会排斥等行为,表明嫉妒和竞争在灵长类中具有进化的根源。 Scientists observed behaviors like aggression, competition for food and maternal attention, and social exclusion among siblings, suggesting jealousy and rivalry have evolutionary roots in primates. 研究结果突显了浣熊群中复杂的社会动态,并表明这种行为可能在不同物种之间共享,尽管有关的确切情感经历仍然不清楚。 The findings highlight complex social dynamics in baboon groups and indicate that such behaviors may be shared across species, though the exact emotional experiences of baboons remain unclear.
