Using simple local behaviors based on chemotaxis, the mobile agent population spontaneously forms complex and dynamic transport networks. Clearly, Physarum is an ideal model for understanding chromatin replication and presents features also found in higher eukaryotes like the lack of genetic replication origins, a close relationship between replication and transcription. It consumes bacteria and decaying organic matter. Physarum plasmodia are usually 3 or 4 cm ( ½ - 1 " ) in diameter, but can get to be 30 cm (about 1 foot) or more in diameter, and 3 to 5 cm thick.
