Evolution of basic body plan of animal is investigated theoretically. We study swimming behaviour of Anomalocaris in water by performing hydrodynamical calculation. Anomalocarid arthropod is the largest known predatory animal of middle Cambrian. As a result of simulation using moving particle method possible swimming motion of Anomalocaris is obtained. In the computer we can change the morphology from known bauplan of Anomalocaris found as fossil record. It makes us possible to discuss on the variants of Anomalocaris at the intermediate state of evolution process. Such new methodology using computer reveals how and from where Anomalocaris evolved.

从理论上探讨了动物基本体型的演变。通过水动力计算，研究了异形线虫在水中的游动行为。异果类节肢动物是中寒武世已知的最大的捕食性动物。通过移动粒子法的模拟，得到了异形线虫可能的游动运动。在计算机中，我们可以改变已知的无尾轮虫的形态，作为化石记录。这使得我们有可能讨论处于进化过程中间状态的异型变种。这种使用计算机的新方法揭示了变形虫是如何进化的以及从哪里进化出来的。
