In a pollinator-free common garden, wild woodland strawberry (*Fragaria vesca*) genotypes exhibit a geographic trade-off in reproductive assurance strategies, with southern European populations favoring self-fertilization and eastern populations relying more on clonal reproduction, both associated with reduced petal size.
This study presents the first range-wide genomic analysis of the eastern oyster (*Crassostrea virginica*), revealing distinct Gulf and Atlantic ancestral clusters, unexpected human-mediated genetic mixing, and climate-adaptive loci to inform future aquaculture breeding programs.
This study resolves the long-standing debate on the evolutionary origins of spider orb-weaving by using comparative transcriptomic analysis of 98 species to identify specific genetic signatures of convergent positive selection and gene copy number changes, thereby clarifying whether the trait evolved independently or was lost in non-orb-weaving descendants.
This study demonstrates that mating systems critically influence a population's ability to undergo evolutionary rescue and avoid extinction, where mate choice in polygynous systems accelerates adaptation in large populations but increases extinction risk in small ones by rapidly depleting genetic diversity.
This paper presents a simulation model based on estimation-of-distribution algorithms that demonstrates how nonrandom, non-Lamarckian mutations, driven by internally accumulated genomic information, interact with selection and recombination to advance evolution, thereby offering a computational framework that aligns with Interaction-based Evolution theory and connects to Darwinian observations and computational learning theory.
This study identifies an evolutionarily conserved dorsal-retina-specific enhancer cluster that regulates *efnb2* expression through a topologically associating domain, linking this regulatory architecture to human retinal thickness variation.
This study reveals that the facultatively parthenogenetic stick insect *Megacrania batesii* exhibits remarkable flexibility in its reproductive mechanisms, with variation occurring both between lineages and within individuals, leading to diverse genetic outcomes that may influence the long-term persistence of parthenogenetic lineages.
This study reports the first verified discovery of a highly prevalent, multicopy "Mega-NUMT" in the neotropical fruit fly *Drosophila paulistorum*, demonstrating that such large-scale mitochondrial-to-nuclear DNA transfers can persist in nature at high frequencies, likely maintained by balancing selection.
This study utilizes single-cell sequencing across the entire life cycle of the larvacean *Oikopleura dioica* to map its cellular diversity and characterize the molecular signatures of the specialized house-producing epithelium, thereby providing a critical resource for understanding chordate evolution and organ morphogenesis.
By applying low-coverage shotgun sequencing to 152 herbarium specimens spanning two centuries, this study reconstructs the global invasion history of Japanese knotweed, revealing Japan as the source of introductions, the post-introduction origin of European and North American hybrids, and the long-term genetic uniformity of invasive populations driven by vegetative reproduction.
This study demonstrates that mitonuclear genomic compatibility in *Drosophila melanogaster* significantly shapes male cuticular hydrocarbon profiles through non-additive interactions, ultimately driving female mate choice and determining reproductive success.
This study demonstrates that in the stalked jellyfish *Haliclystus sanjuanensis*, the regression of juvenile tentacles during limited metamorphosis is driven by a loss of cell proliferation, whereas the development of adult structures like anchors involves a gain in proliferative cells, suggesting that the continued investment in cell proliferation is a key mechanism for segregating temporary juvenile tissues from permanent adult ones.
By analyzing high-quality genome assemblies and population data across the *Mercurialis* genus, this study reveals that the *M. annua* Y chromosome evolved through two distinct stages of recombination suppression involving a recent inversion and an older degenerated stratum, while identifying *APRR7* as a conserved candidate master sex-determination gene.
This study demonstrates that structural selection in ecological networks is only detectable when analyzing meso-structural domains via order-2 egonets, as aggregated network representations obscure the hierarchical heterogeneity necessary for evolutionary gradients to emerge.
This study resolves a long-standing question in mitochondrial evolution by identifying the bacterial inner membrane transporters CysZ and YihY as the evolutionary ancestors of the mitochondrial ATP/ADP carrier (AAC), thereby establishing a bacterial origin for this critical eukaryotic protein.
This study demonstrates that unidirectional cross-feeding in microbial communities constrains adaptive evolution in both the producer and consumer species by increasing purifying selection and lineage diversity, even when the fitness benefits are not reciprocated.
This paper introduces a scalable Bayesian measure of phylogenetic information content based on geodesic distances in treespace, which quantifies the reduction in tree variance from prior to posterior distributions to assess data informativeness and detect conflicts among datasets.
This study demonstrates that photosynthetic algal endosymbionts act as primary organizers of the host *Paramecium bursaria*'s diel transcriptome by driving rhythmic gene expression across diverse biological processes through photosynthesis-dependent mechanisms, a phenomenon also observed in the independently evolved symbiont *Tetrahymena utriculariae*.
This study reveals that global invasions of the ambrosia beetle *Euwallacea fornicatus* are structured by a dominant, genetically depauperate lineage derived from a bridgehead population, while subsequent hybridization with local lineages in regions like South Africa facilitates the purging of deleterious mutations, thereby enhancing the biosecurity threat posed by these invasive beetles.
Population genomics analysis of the grass puffer (*Takifugu alboplumbeus*) reveals that geographic differences in lunar-regulated spawning timing between western and eastern Japanese populations are driven by variations in the free-running circadian period associated with missense mutations in the *prrt1l* gene.
