毫无争议的是，陆地动物比鱼类等水生动物具有更复杂的认知能力。然而，这并没有明显的先验原因。一个关键的认知能力是计划。我们表明，在视觉引导的捕食者与猎物互动中，规划提供了显着的优势，但仅限于陆地。在动物进化过程中，从水到陆地的转变导致了视觉范围的大幅增加。行为模拟确定了特定类型的陆地栖息地、聚集的开放和封闭区域（类似稀树草原），其中规划的优势达到顶峰。我们的计算实验展示了这种斑驳的陆地结构如何与增强的视觉范围相结合，如何根据代理的运动来揭示和隐藏代理，并为想象、评估和选择未来可能的场景（简而言之，为规划）创造选择性利益。脊椎动物对陆地的入侵可能是其认知进化的重要一步。
It is uncontroversial that land animals have more elaborated cognitive abilities than their aquatic counterparts such as fish. Yet there is no apparent a-priori reason for this. A key cognitive faculty is planning. We show that in visually guided predator-prey interactions, planning provides a significant advantage, but only on land. During animal evolution, the water-to-land transition resulted in a massive increase in visual range. Simulations of behavior identify a specific type of terrestrial habitat, clustered open and closed areas (savanna-like), where the advantage of planning peaks. Our computational experiments demonstrate how this patchy terrestrial structure, in combination with enhanced visual range, can reveal and hide agents as a function of their movement and create a selective benefit for imagining, evaluating, and selecting among possible future scenarios—in short, for planning. The vertebrate invasion of land may have been an important step in their cognitive evolution.
