Therefore, it is widely understood as a valuable tool for investigating global properties of evolutionary processes. Cognizant of refined concepts that emerged in recent debates on the central role of historical contingency (historicity) in evolution, we modify the original GoL rules by introducing an updating feedback loop and a probability factor that reflect the degree of historicity in pattern evolution as both stochastic path dependence and sensitivity to initial conditions. We examine this trait in simulations of the emergence and breaking of bilateral and radial symmetries commonly observed in the evolution of life, most prominently as evolving body plans. We show that the implementation of historicity parameters leads to a more realistic sequential and gradual alternating emergence and the breaking of new symmetries than the original set of rules. Apart from its more realistic representations of evolutionary processes, the new approach allows for easier exploration of the parameter space, demonstrates the sequential and gradual emergence and breaking of symmetries, and provides a publicly available and modular simulation tool. We discuss the exploratory potential of the modified GoL platform we designed as an extended thought experiment to study the parameter space defining the historicity of biological processes.<\/jats:p>","DOI":"10.3390\/sym16081024","type":"journal-article","created":{"date-parts":[[2024,8,12]],"date-time":"2024-08-12T05:19:38Z","timestamp":1723439978000},"page":"1024","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Symmetry and Historicity in the Game of Life: Modifying Rules to Simulate Evolutionary Dynamics"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4655-5063","authenticated-orcid":false,"given":"Jovan M.","family":"Tadi\u0107","sequence":"first","affiliation":[{"name":"Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9476-7445","authenticated-orcid":false,"given":"Andrej","family":"Koreni\u0107","sequence":"additional","affiliation":[{"name":"Department of Physiology and Biochemistry, Faculty of Biology, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4393-4105","authenticated-orcid":false,"given":"Slobodan","family":"Perovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Philosophy, Faculty of Philosophy, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"McConwell, A.K.
