Evolution of simple multicellular life cycles in a dynamic environment — •Yuriy Pichugin and Hye Jin Park — Max Planck Institute for Evolutionary Biology, August-Thienemann-Str. 2 24306 Plön

Reproduction is a defining feature of living systems. To reproduce multicellular organism must fragment into smaller parts. To investigate evolutionarily optimal strategies of fragmentation under the dynamic environment, we use the model in which groups arise from the division of cells that do not separate but stay together until the moment of group fragmentation. The environmental conditions change in our model by alternating between two seasons, and different group sizes have a different birth rate of cells depending on the season. We outline which fragmentation strategies are evolutionarily optimal at given environmental conditions.
