Animal societies are rife with conflict over resources and reproduction, raising the question of how such societies nonetheless persist. A long-term study on birds shows that larger groups are less likely to go extinct, making individuals offer reproductive concessions to unrelated competitors joining the group.
动物社会充满了资源和繁殖方面的冲突，这引发了一个问题，即这些社会是如何存在的。一项关于鸟类的长期研究表明，较大的群体不太可能灭绝，这使得个体向加入群体的无关竞争者做出繁殖上的让步。
