集体运动产生于个体之间的互动，这种互动产生了群体范围的行为模式。虽然在动物物种中观察到了集体运动的适应性变化，但当这些集体行为演变时，局部相互作用是如何变化的，人们知之甚少。在这里，我们使用墨西哥四齿鱼，Astianax micianus，它以成群的表面形态和非成群的洞穴形态存在，来研究鱼类如何改变它们的游动，以回应个体发育中的邻居和进化上不同的种群之间的差异。我们发现，表层鱼类经历了由鱼类调节速度和相对于邻居转向的方式的变化而转变为鱼群的过程。这种转变开始于受精后28天出现的与邻居结盟的趋势，结束于受精后70天出现强大的吸引力。洞鱼在发育的任何阶段都不表现出排列或吸引。这些结果揭示了进化如何改变局部相互作用，从而在集体行为中产生显著差异。
Collective motion emerges from individual interactions which produce group-wide patterns in behavior. While adaptive changes to collective motion are observed across animal species, how local interactions change when these collective behaviors evolve is poorly understood. Here, we use the Mexican tetra,Astyanax mexicanus,which exists as a schooling surface form and a non-schooling cave form, to study differences in how fish alter their swimming in response to neighbors across ontogeny and between evolutionarily diverged populations. We find that surface fish undergo a transition to schooling mediated by changes in the way fish modulate speed and turning relative to neighbors. This transition begins with the tendency to align to neighbors emerging by 28 days post-fertilization and ends with the emergence of robust attraction by 70 days post-fertilization. Cavefish exhibit neither alignment nor attraction at any stage of development. These results reveal how evolution alters local interactions to produce striking differences in collective behavior.
