    "abstract": "At an early stage in pre-biotic evolution, groups of replicating molecules\nmust coordinate their reproduction to form aggregated units of selection.\nMechanisms that enable this to occur are currently not well understood. In this\npaper we introduce a deterministic model of primitive replicating aggregates,\nproto-organisms, that host populations of replicating information carrying\nmolecules. Some of the molecules promote the reproduction of the proto-organism\nat the cost of their individual replication rate. A situation resembling that\nof group selection arises. We derive and analytically solve a partial\ndifferential equation that describes the system. We find that the relative\nprevalence of fast and slow replicators is determined by the relative strength\nof selection at the aggregate level to the selection strength at the molecular\nlevel. The analysis is concluded by a preliminary treatment of finite\npopulation size effects.",
