Abstract (auf Englisch):

The evolution of chromosomes, the eukaryotic and the plant cell all involved the coming together of separate autonomously reproducing entities to form self-replicating structures. However, the Darwinian property of heredity is not a given at the collective level and the evolution of specific mechanisms of heredity must be explained. I will present a simple model in which particles reproduce within collectives, that are in turn subject to a birth-death process. We will see that that selection acting on population of collectives drives evolution of individual traits toward ecological regimes insuring the reliable transmission of collective traits across collective generations. Our model establishes an ecological recipe for effecting major egalitarian transitions and has implications for top-down engineering of microbial communities.
