Multi-level selection in a simple artificial chemistry

McMullin, Barry orcid logoORCID: 0000-0002-5789-2068, Kelly, Ciarán and O'Brien, Darragh (2007) Multi-level selection in a simple artificial chemistry. In: 9th European Conference, ECAL 2007, 10-14 Sept 2007, Lisbon. ISBN 978-3-540-74913-4

We describe a simple artificial chemistry which abstracts a small number of key features from the origin of life “replicator world” hypotheses. We report how this can already give rise to moderately complex and counter-intuitive evolutionary phenomena, including macroevolutionary deterioration in replication fidelity (which corresponds to intrinsic replicator fitness in this model). We briefly describe the extension of this model to incorporate a higher, protocell, level of selection. We show that the interaction between the two levels of selection then serves to control parasitic exploitation at the molecular level, while still significantly constraining accessible evolutionary trajectories at the protocell level. We conclude with a brief discussion of the implications for further work.
