| Research Abstract |
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.
