This study identifies a horizontally acquired mitochondrial alternative oxidase in springtails, showing its role in hypoxia tolerance and adaptation to belowground environments.

The paper shows that engineered synonymous mutations disrupting RNA structural elements increase de novo mutations in a virus, suggesting structural perturbations affect genomic stability.

The paper examines the evolutionary tradeoff between horizontal and vertical gene transfer in plasmids, finding mixed evidence and proposing that HGT relaxes constraints by introducing plasmids into novel hosts.

The paper investigates ZGA timing across 61 animal species and finds that genome size to cytoplasm volume ratio predicts ZGA onset.

This study analyzes PRPS enzyme evolution across domains of life, identifying new classes and regulatory mechanisms through phylogenetic and biochemical approaches.

This study estimates a thermal adaptation lag of 1.91°C in Arabidopsis thaliana, indicating populations are better adapted to cooler climates than their home environments.

This study uses genomic data to show that climate and sea-level changes drove lineage diversification in Venus flytraps, with population declines linked to historical climate optima and human impacts.

The paper quantifies origin-dependent fitness differences in Atlantic salmon by analyzing reproductive success of local and immigrant individuals over 15 years.

This study uses microcomputed tomography to analyze Neanderthal juvenile fossils, revealing similarities in bone growth patterns to modern humans and suggesting possible systemic disorders in tooth development.

The paper analyzes genomic changes in mini-chromosomes of wheat blast fungal pathogens over time, showing their dynamic presence, sequence alterations, and role in pathogen adaptation.

The paper introduces HyperMk2, a method to efficiently model the coevolution of multiple binary characters by reducing state space, enabling analysis of larger systems than previous methods.

The paper uses simulations to show that deleterious mutations reduce inversion fixation probabilities, but lucky inversions can still fix and influence macroevolution.

The paper resolves a long-standing paradox in lysozyme evolution by showing that recombination and incomplete lineage sorting explain apparent molecular convergence without requiring fixation of deleterious intermediates.

The paper compares the effects of mutational drought and meltdown on extinction risk in small populations, finding mutational drought is more significant in stable and changing environments.

DeMoDa provides an open-access database of 17,308 human dental traits across 32 regions, enabling comparative research on dental morphology and its genetic basis.

This study examines how urbanization and ecological factors influence song frequency traits in Spotted and Eastern towhees using geographic and environmental data.

This study identifies genomic and proteomic adaptations in two snail lineages that independently evolved aerial egg deposition, revealing convergent evolutionary mechanisms and horizontal gene transfer.

This study shows condition-dependent selfing generates within-population variation in selfing rates and contributes to mating-system diversity.

The paper shows a trade-off between competitive ability and host colonization in Pseudomonas populations has persisted for centuries.

This study sequenced whole genomes of black-footed cats to analyze their population structure and genetic diversity, finding low diversity but no long runs of homozygosity and evidence of recent population contraction.
