The evolution of the mammalian middle ear from the jaw hinge of non-mammalian synapsids offers a deep-time perspective on sensory evolution but is limited by a poor understanding of early synapsid hearing. This work tests the hypothesis that the size of the reflected lamina of the angular bone in non-mammalian synapsids followed a strict, negative allometric trend that may be expected for a sound receiver. Allometry is first investigated in the pterygoid bone of chameleons, which was co-opted for hearing in some species and represents a possible analog for the synapsid reflected lamina. Results indicate that chameleons with a pterygoid ear exhibit a similar allometric slope, while species without a pterygoid ear have variable slopes, suggesting an optimum allometric pattern in sound receivers. In the reflected lamina, we find reduced variation around the allometric trend in therocephalians and non-bidentalian anomodonts, and evolutionary modeling suggests constraint in these groups. These results are consistent with a mandibular middle ear in non-mammalian synapsids, adding valuable new insights to the hypothesis that selective pressures for hearing ability were present long before the evolution of the mammalian middle ear.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"905-921"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143482553","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}

While much attention has been given to color pattern variation in the human-visible range, perception outside this range is observed in a wide array of species and is poised to influence color pattern evolution. Butterfly species often show sensitivity to ultraviolet (UV) light, impacting wing color pattern diversification as their evolution is influenced by both predator vision and sexual selection. Here, we explore UV color pattern diversification in Papilionidae within a comparative phylogenetic framework by quantifying variation from UV photographs of museum specimens using a machine-learning-based method. We find decoupled dorsal and ventral UV color pattern evolution, with brighter and more rapidly evolving ventral sides, especially in males. Conversely, we find a smaller dorso-ventral difference in visible-light color patterns. Moreover, we find divergence in male ventral UV patterns in closely related sympatric species, even after accounting for variation due to visible-light patterns. These results suggest an influence of sexual selection on UV ventral pattern diversification. These findings highlight how the trade-off between sexual and natural selection may lead to contrasted evolution of ventral vs. dorsal sides of the same organ.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"995-1006"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572046","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 the weak mutation and rare migration regime, we find that, in most landscapes, migration asymmetries associated with some suppression of natural selection allow the population to reach higher fitness peaks first. In this sense, suppression of selection can make early adaptation more efficient. However, the time it takes to reach the first fitness peak is then increased. We also find that suppression of selection tends to enhance finite-size effects. Finite structures can adapt more efficiently than very large ones, especially in high-dimensional fitness landscapes. We extend our study to frequent migrations, suggesting that our conclusions hold in this regime. We then investigate the impact of spatial structure with rare migrations on long-term evolution by studying the steady state of the population with weak mutation, and introducing an associated steady-state effective population size. We find that suppression of selection is associated to small steady-state effective population sizes and thus to small average steady-state fitnesses.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"935-950"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556392","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}

Our results show that the Meconopsis-Oreomecon clade colonized the Arctic from the QTP in the Late Eocene, suggesting the hitherto earliest known dispersal event between two regions. The Arctic Oreomecon split from the QTP Meconopsis at ~34 Ma, associated with their climatic niche differentiation and aridification of the Asian interior. Although both Oreomecon and Meconopsis preadapted to open and low-temperature environments and had similar diversification patterns, they diversified asynchronously in respondence to different Cenozoic climate cooling events. The Arctic is approaching its carrying capacity, whereas the QTP is still far from saturation.

Neutral theory predicts a positive correlation between population (or range) size and genetic diversity, but this can be confounded by other demographic processes. To investigate the role of range size, population fluctuation, and introgression in determining genetic diversity, we generate and analyze population-level, genomic-scale SNP data from 21 species of Australian Gehyra geckos (769 samples) that vary in range size over three orders of magnitude. Using a best-practice approach to estimate heterozygosity, we found a significantly positive overall correlation between range size and heterozygosity (R2 = 0.30, p < 0.01), although with a shallow slope, consistent with Lewontin's Paradox. At a clade level, we show a stronger relationship between range size and heterozygosity in the australis group (R2 = 0.74, p < 0.01) than in the nana group (R2 = 0.15, n.s.). A significantly negative correlation between genome-wide Tajima's D and range size in both groups, indicating population expansion, and evidence for introgression in the nana group, suggest a role for both population fluctuation and introgression in driving deviations from theoretical expectations.

These types of insights could have theoretical and applied applications, particularly as the climate continues to change. We interrogate repeated molecular adaptation across 13 eucalypt species. In total, we found 38 candidate genes with shared putatively adaptive signals in as many as 12 species. This suite of genes contains important functions, including myeloblastosis (MYB) proteins, acyl-CoA dehydrogenases, and Leucine-rich kinases. Species with restricted and widespread geographical distributions shared putative patterns of adaptation, and phylogenetic closeness did not increase patterns of repeated adaptation compared to geographic overlap.

Two main hypotheses have been proposed for how territoriality and mating competition impact sex-biased dispersal. Female-biased dispersal is expected in monogamous systems with male resource defense, whereas male-biased dispersal is expected in polygynous systems with male competition over mates. However, patterns of sex-biased dispersal in socially polyandrous species, where females compete for both territories and mates, remain poorly understood. We investigated sex-biased dispersal in 2 polyandrous Jacana species across Central America, the Northern Jacana (Jacana spinosa) and Wattled Jacana (J. jacana), which exhibit intense female-female competition for territories and mates and differ in the strength of sexual selection. We analyzed sex-biased dispersal by assessing genetic differentiation and individual assignment indices to determine the probability of an individual being a recent immigrant or philopatric in relation to its sampling location. Our findings reveal strong male-biased dispersal in Northern Jacanas, indicated by higher genetic structuring and philopatry in females. In contrast, Wattled Jacanas showed no significant dispersal bias between sexes. Furthermore, sexually selected traits in Northern Jacana females, such as larger body mass and wing spur length, were associated with philopatry, suggesting that larger females retain territories, whereas smaller females disperse. To our knowledge, this is the first genetic evidence of male-biased dispersal in a polyandrous species. Our findings reveal that sexually selected traits, in addition to territorial and mate competition, are important for understanding species and sex differences in dispersal evolution.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1096-1105"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143751767","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}

Percomorpha, comprising over 18,900 species, includes nearly one third of living vertebrates. However, the phylogenetic resolution of its sister lineage remains unclear, obscuring whether contrasts in histories of diversification provide insights into the factors that gave rise to this clade's high diversity. Using 887 ultraconserved element loci and eight Sanger-sequenced nuclear genes, we resolve the phylogenetic relationships of the three closest relatives of Percomorpha-the roughies, flashlightfishes, porcupinefishes, and fangtooths (Trachichthyiformes), the squirrelfishes and soldierfishes (Holocentridae), and the whalefishes, bigscales, and alfonsinos (Berycoidei)-and the placement of percomorphs among them. Contrary to expectations from the fossil record, we demonstrate that living lineages of Berycoidei, Holocentridae, and Trachichthyiformes all diversified after the Cretaceous-Paleogene mass extinction. Our findings show that multiple clades in Trachichthyiformes and Berycoidei independently colonized deep ocean habitats during the climatically unstable Eocene and Oligocene and shallow-water reefs during the marine biodiversity hotspot migration and faunal turnover of the Early Miocene. These invasions coincided with the evolution of novel life history traits, including pelagic cnidarian-mimicking larvae and extreme sexual dimorphism in some deep-sea forms. Because of their recent invasions of these habitats, the closest relatives of Percomorpha are not ideal for understanding the origins of this exceptionally species-rich clade in the marine realm.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"922-934"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556390","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}

However, the underlying mechanisms that maintain trade-offs or allow organisms to resolve them via phenotypic plasticity are often challenging to detect. The trade-off between gas exchange and water loss across respiratory surfaces represents a fundamental trade-off that constrains phenotypic diversity in terrestrial life. Here, we investigate plastic mechanisms that mitigate this trade-off in lungless salamanders that breathe exclusively across their skin. Our field and laboratory experiments identified plastic responses to environmental variation in water loss and oxygen uptake, and gene expression analyses identified putative pathways that regulate this trade-off. Although the trade-off was generally strong, its strength covaried with environmental conditions. At the molecular level, antagonistic pleiotropy in multiple biological pathways (e.g., vasoconstriction and upregulation of aerobic respiration) putatively produce the trade-off, while other pathways mitigate the trade-off by affecting a single trait (e.g., oxygen binding affinity, melanin synthesis). However, organisms are likely to encounter novel trade-offs in the process of bypassing another. Our study provides evidence that alternative pathways allow organisms to mitigate pleiotropic conflicts, which ultimately may allow greater phenotypic diversity and persistence in novel environments.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1073-1085"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143647810","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}
