Central theories explaining the maintenance of individual differences in behavior build on the assumption that behavior mediates life-history trade-offs between current and future reproduction. However, current empirical evidence does not robustly support this assumption. This mismatch might be because current theory is not clear about the role of behavior in individual allocation versus acquisition of resources, hindering empirical testing. The relative importance of allocation compared to acquisition is a key feature of classic life-history theory, but appears to have been lost in translation in recent developments of life-history theory involving behavior. We argue that determining the relative balance between variation in resource allocation and acquisition, and the role of behavior in this process, will help to build more robust and precise predictions.

解释维持行为个体差异的中心理论建立在以下假设基础上：行为介导了当前和未来再生产之间的生命历史权衡。但是，当前的经验证据不能强有力地支持这一假设。这种失配可能是因为当前的理论尚不清楚行为在个人分配与资源获取中的作用，从而阻碍了实证检验。与习得相比，分配的相对重要性是经典生活史理论的一个关键特征，但是在涉及行为的生活史理论的最新发展中，翻译似乎已经失去了它。我们认为，确定资源分配和获取变化之间的相对平衡以及行为在此过程中的作用，
