This study re-evaluates barley domestication history using genetic data, showing a monophyletic origin and identifying the Fertile Crescent as the likely domestication site.

This study shows that ablating the Atp1b4 gene in mice reduces obesity and improves metabolic parameters by disrupting evolutionarily acquired BetaM functions.

The paper examines mammalian evolutionary constraint at synonymous sites, finding significant constraint in 20.8% of four-fold degenerate sites and biases toward G/C content and splice sites.

This study identifies optimal environmental cues for malaria parasites to maximize reproductive success by analyzing how different cues affect transmission investment strategies.

The paper selects for large body size in black soldier flies and finds repeatable phenotypic but not genetic responses, highlighting high genetic redundancy in polygenic traits.

This study shows triploid hybrids facilitate gene flow between diploid and tetraploid Cardamine amara populations, overcoming ploidy barriers through bidirectional introgression.

The paper reports rapid chromosomal changes in spiral egg clade fishes, finding high variability in chromosome counts and arm numbers, suggesting rapid chromosome loss and large-scale mutations.

This study examines genomic adaptations of ambrosia fungi across multiple lineages, finding lineage-specific changes rather than genome-wide reductions or convergent evolution.

This study analyzes TPE genome sequences to investigate host ancestry and cross-species transmission, finding limited interaction between human and non-human primate infections.

This study identifies synovial joints in elasmobranchs but not cyclostomes, suggesting their origin in the common ancestor of jawed vertebrates.

This study uses genomic data to reconstruct the evolutionary history of Linanthus species, revealing complex speciation patterns and trait evolution in arid environments.

The study tracks genomic changes in wMel Wolbachia over six years in three Aedes aegypti populations and finds minimal evolution, supporting its stability as a biocontrol agent.

ERC2.0 improves functional interaction prediction across large phylogenies by enhancing algorithm speed, normalization, and statistical power.

The paper investigates structural variants in seed beetles, linking them to rapid evolution of sex chromosomes and sex-biased gene expression.

The paper identifies a previously unknown bioregion between tropical and temperate zones that explains latitudinal biodiversity and phylogenetic gradients through simulations.

The paper introduces an R package called pholidosis for analyzing and comparing biological surface patterns as networks, using an edit distance metric for comparative analysis.

The paper introduces a network-based method to compare homologous two-dimensional patterns, demonstrating its application to reptile scalation patterns.

This study shows that heterogeneous population structures can increase evolutionary rates and alter genetic variation dynamics, challenging prior assumptions about structured populations slowing evolution.

The paper investigates dioicy-monoicy transitions in liverworts, confirming monoicy evolved from a dioicous ancestor and describing potential re-evolution of dioicy with new sex chromosome formation.

The paper identifies slab photonic crystals in diatom girdle bands using FFT analysis across 393 SEM images, revealing their distribution and photonic properties across taxonomic groups.
