Mutualistic M\u00fcllerian mimicry is a compelling example of an ecological interaction that affects population and species ecology and evolution. Here, we test how M\u00fcllerian mimicry shapes macroevolutionary patterns of diversification in the Ithomiini butterflies. We show that the age of color patterns is the most important predictor of species richness within mimicry rings but does not predict phylogenetic diversity of mimicry rings. We find pervasive phylogenetic signal in mimicry rings and in color patterns associated within polymorphic species. Only a small set of mimicry rings show high phylogenetic diversity. We identify patterns of saturation in the accumulation of new mimicry rings and in the number of evolutionary convergences toward the most species-rich mimicry rings. We discuss how the time-dependent effects detected in our study illustrate how neutral processes and ecological interactions interact and shape species and phenotypic diversification. Our results show that selection driven by mimetic interaction has not erased the effect of time and phylogenetic signal on the formation of mimicry rings but ecological saturation linked to mimetic interactions affected the dynamics of color pattern evolution and species diversification.", "doi": "10.1086/735835", "pmid": "40577833", "labels": {"Mariana Pires Braga": null, "DDLS Fellow": null}, "xrefs": [], "notes": [], "created": "2025-11-28T12:32:13.598Z", "modified": "2025-11-30T11:16:52.763Z"}, {"entity": "publication", "iuid": "b837a84ffda94d9e83cc9cc8229e3422", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/b837a84ffda94d9e83cc9cc8229e3422.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/b837a84ffda94d9e83cc9cc8229e3422"}}, "title": "Evolution of the G Matrix under Nonlinear Genotype-Phenotype Maps.", "authors": [{"family": "Milocco", "given": "Lisandro", "initials": "L"}, {"family": "Salazar-Ciudad", "given": "Isaac", "initials": "I"}], "type": "journal article", "published": "2022-03-00", "journal": {"title": "Am Nat", "issn": "1537-5323", "volume": "199", "issue": "3", "pages": "420-435", "issn-l": null}, "abstract": "AbstractThe G matrix is a statistical summary of the genetic basis of a set of traits and a central pillar of quantitative genetics. A persistent controversy is whether G changes slowly or quickly over time. The evolution of G is important because it affects the ability to predict, or reconstruct, evolution by selection. Empirical studies have found mixed results on how fast G evolves. Theoretical work has largely been developed under the assumption that the relationship between genetic variation and phenotypic variation-the genotype-phenotype map (GPM)-is linear. Under this assumption, G is expected to remain constant over long periods of time. However, according to developmental biology, the GPM is typically complex and nonlinear. Here, we use a GPM model based on the development of a multicellular organ to study how G evolves. We find that G can change relatively fast and in qualitative different ways, which we describe in detail. Changes can be particularly large when the population crosses between regions of the GPM that have different properties. This can result in the additive genetic variance in the direction of selection fluctuating over time and even increasing despite the eroding effect of selection.", "doi": "10.1086/717814", "pmid": "35175900", "labels": {"DDLS Fellow": null, "Lisandro Milocco": null}, "xrefs": [{"db": "Dryad", "key": "10.5061/dryad.z34tmpgck"}], "notes": [], "created": "2025-11-28T14:28:18.929Z", "modified": "2025-11-28T14:28:57.262Z"}], "created": "2025-11-28T12:32:13.608Z", "modified": "2025-11-28T12:32:13.608Z"}
