These insects act as agents of selection among plants and animals, driving ecological and evolutionary shifts in disparate groups across the tree of life. Obligate consumers of ants or termites, called myrmecophages, exhibit morphological adaptations such as lengthened tongues and reduced teeth that are associated with a bulk feeding strategy. Though a typifying feature of some mammal lineages, the macroevolutionary history of obligate myrmecophagy and its relationship to social insect evolution is unknown. We report large-scale patterns of myrmecophagous evolution through a synthesis of the social insect fossil record, ant and termite evolutionary history, and mammal natural history data spanning 4,099 species. Specialized ant and termite feeding has arisen at least 12 times in mammals and through multiple pathways; transitions to myrmecophagy stem from insectivorous and carnivorous ancestors. We recover one reversal out of social insect feeding, perhaps owing to food source stability or difficulty in regaining generalist features. Despite the contemporary ubiquity of social insects, their history suggests a recent capacity for specialist consumers. While both lineages originated in the Cretaceous, rising fossil prevalence of ants and termites and their acquisition of large colony sizes predominantly occurred in the Cenozoic.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the effects of parasitism by the cestode Anomotaenia brevis on colonies of its intermediate host, the ant Temnothorax nylanderi. We evaluated changes in worker and queen survival rates and transcriptional activity in the fat body of infected and uninfected workers, as well as in the parasite itself, in relation to infected worker prevalence and colony size. Cestode-infected workers are known to exhibit a significantly extended lifespan compared to uninfected workers. Here, we demonstrate that the survival rates of infected workers, uninfected queens, and uninfected workers decrease with increasing infected worker prevalence and increase with colony size. Transcriptomic analysis revealed stress-related signatures in all workers, regardless of infection status, as infection prevalence increased. Moreover, gene expression patterns, particularly in uninfected workers, were strongly influenced by colony size. The transcriptional activity of the parasitic cestode also shifted with infected worker prevalence, highlighting the complex dynamics of host-parasite interactions. These results demonstrate that parasites in social species impose colony-wide impacts that extend beyond infected individuals, even in the absence of direct cross-nestmate infection risks. Moreover, the consequences of parasitism can be modulated by colony size.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A time-calibrated phylogeny indicated reciprocal monophyly of S. alpinus and S. malma, that the species diverged an estimated ∼1.4 million years ago, and that eastern Pacific Southern Dolly Varden (S. m. lordi) is the basal lineage within S. malma.

We found strong evidence for a model of divergence without gene flow between S. alpinus and S. malma followed by secondary contact about 14,500 years ago with subsequent gene flow.

Despite the importance of keeping telomere length within a critical homeostatic range, adult telomere length can differ by two orders of magnitude across vertebrate species. Why telomere length varies so widely remains unknown, though popular hypotheses suggest that body size, lifespan, and endothermy are key variables that have coevolved with telomere length. To test the relationship among telomere length, telomerase activity (which extends telomeres), and these variables, we modeled the evolution of telomere length across 122 vertebrate species. We failed to find an influence of body mass, lifespan, or baseline metabolism on telomere length. However, we found a significant interactive effect between baseline metabolism and body mass. The presence of telomerase activity was positively correlated with telomere length across the 58 species where data for both existed. Taken together, our findings suggest that body mass may have differentially influenced the evolution of telomere length in endotherms and ectotherms and indicate that telomerase activity and telomere length may have coevolved.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144186795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we used geometric morphometric and phylogenetic comparative methods to evaluate the tempo and mode of morphological evolution in an adaptive radiation of Malagasy birds, the vangas, and their mainland relatives (Aves: Vangidae). The Malagasy radiation is more diverse in both skull and foot shape. However, rather than following the classic \"early burst\" of diversification, trait evolution accelerated well after their arrival in Madagascar, likely driven by the evolution of new modes of foraging and especially of a few species with highly divergent morphologies. Anatomical regions showed differing evolutionary patterns, and the presence of morphological outliers impacted the results of some analyses, particularly of trait integration and modularity. Our results demonstrate that the adaptive radiation of Malagasy vangas has evolved exceptional ecomorphological diversity along multiple, independent trait axes, mainly driven by a late expansion in niche space due to key innovations. Our findings highlight the evolution of extreme forms as an overlooked feature of adaptive radiation warranting further study.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144173358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This implies that the regulatory mechanisms through which environmental factors shape the phenotype during ontogeny could be heritable and potentially evolve by natural selection. The present study provides experimental evidence of the potential response to selection of flower developmental stability by estimating the additive genetic (co)variance matrix of within-individual variation of morphometric flower traits and testing its evolutionary potential in a natural population. We employed a partial-diallel crossing design, growing plants of the annual Solanum rostratum under controlled greenhouse conditions. Our phenotypic variance partitioning analysis showed significant additive genetic within-individual variances and covariances for some, but not all, floral traits. Multivariate analysis showed a lower number of significant additive genetic covariances for the within-individual variation compared with genotypic means. For those traits with significant additive genetic variation, we found that within-individual variation exhibited higher evolvability compared to genotypic means. These differences in the G-matrix components suggest that the genetic architecture responsible for the expression of means and variances may not be entirely shared. Although this aligns with available genomic evidence for plants, there is not yet available for the floral traits presented here. Overall, the evidence presented in this study indicates that unlike genotypic means, the evolvability of the developmental stability in morphometric flower traits is primarily constrained by the magnitude of additive genetic variance, rather than to the limited number of additive genetic covariances.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144157461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(i) Environmental robustness can boost evolvability by allowing populations to spread across a migrationally-neutral network of demes, and thereby increasing the diversity of plastic phenotypes that can be accessed by migration. (ii) Counter-intuitively, when adaptive landscapes are complex, an increase in environmental stability can increase the frequency of environmentally-robust but mutationally-sensitive genotypes. This is appears to be due to relaxed selection for mutational robustness in generalists. (iii) Evolvability can be affected by changes in mutational sensitivity, or by changes in the neighborhood of phenotypes accessible by non-neutral mutations. Because it allows for the evolution of increased evolvability without a concomitant increase in genetic load, selection should favor changes in the phenotypic neighborhood over changes in mutational sensitivity. Moreover, with fluctuating selection, the potential gains in evolvability conferred by increased mutational sensitivity can be diminished by selective sweeps on the phenotypic neighborhood.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144157459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We quantified F1 hybrid male sterility and characterized multiple phenotypic causes associated with developmental abnormalities in the germline as well as non-germline gonad and somatic tissues, uncovering a complex suite of developmental defects contributing to strong postzygotic reproductive isolation. Despite these multifarious isolating barrier traits, assays testing for interspecies sperm transfer under \"choice\" conditions did not yield evidence of premating isolation. In contrast to other Caenorhabditis species pairs, we also found no evidence that ectopic sperm migration acts as a postmating-prezygotic barrier. The constellation of phenotypic defects in hybrids points to a polygenic or highly pleiotropic basis for hybrid dysfunction and implicates more rapid evolution of intrinsic postzygotic reproductive isolation than prezygotic isolation in these organisms.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diversity-dependent models of diversification have been used to indirectly infer the relevance of interspecific competition on diversification dynamics. In this study, we develop a new approach that more explicitly incorporates spatial and eco-morphological overlap among species to test how interspecific competition may affect diversification dynamics in deep time. We build different metrics that capture temporal and spatial coexistence, and ecological overlap to test the hypothesis that an increase in the intensity of competition would result in a decrease in speciation and an increase in extinction rate. We test our predictions using the fossil record of North American canids, a group that has been extensively studied and well characterized both ecologically and from a paleontological point of view. We find that interspecific competition only affected diversification dynamics during the early stages of the radiation of canids, resulting in the suppression of speciation rate at the time the clade was expanding in diversity. We find no association between the intensity of the competition and extinction dynamics, nor an association between changes in diversification dynamics and changes in temperature. We discuss the relevance of different factors on driving diversification dynamics changes over time and how evaluating the role of interspecific competition using different metrics that better capture the intensity of competition (as opposed to diversity dependent models) might be a way forward to investigate the role of biotic interactions at deep time.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144127041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
