They rule the roads and, in their wake, even old-style saloons have been supersized. It’s an illusion of consumer choice, says writer and podcaster Coco Khan

Initial reports indicate a car unaffiliated with the race was involved in the incident.

Abstract. Many long-standing questions in population genomics can now be addressed through comparative analyses and by leveraging the vast amount of genomi

Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution,...

Environmental DNA (eDNA) provides powerful insights into species presence and community composition but remains limited in its capacity to infer species abundance or population structure. Here, we sh...

Abstract. Standard methods for estimating the population recombination parameter, ρ, are dependent on sampling individual genotypes and calculating various

Abstract. Genomes contain the mutational footprint of an organism’s evolutionary history, shaped by diverse forces including ecological factors, selective

A century after Turesson introduced ecotypes as locally adapted subunits of species, their origins and nature remain debated. Recent advances in molecular ecology have breathed new life into the ecotype concept and significantly expanded our understanding of how ecotypes form. Here, we clarify how ecotypes can be distinguished from other forms of local adaptation, outline criteria for their recognition, and synthesise evidence on the ecological and evolutionary processes that give rise to them. We then evaluate what genomics has uncovered about the origin of ecotypes, revealing pronounced roles of pre-existing variation, large-effect loci, structural variants, gene regulation, and complex demographic histories. Our framework refines Turesson’s concept and highlights outstanding questions about the predictability, persistence, and evolutionary significance of ecotypes.

Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

Understanding how life is adapting to urban environments represents an important challenge in evolutionary biology. In this work, we investigate a widely cited example of urban adaptation, Culex pipie...

The most recent common ancestor of the stony coral Scleractinia dates to about 460 million years ago and was probably a solitary, heterotrophic and free-living organism.

The nature of standing genetic variation remains a central debate in population genetics, with differing perspectives on whether common variants are almost always neutral as suggested by neutral and n...

A growing body of empirical research shows that interspecific gene flow is a widespread biological force that shapes evolutionary histories across the Tree of Life. Computational approaches designed t...

How do new species arise? This is among the most fundamental questions in evolutionary biology. The first genetic model for how reproductive barriers lead to the origin of new species was proposed nea...

Accurate estimation of effective population size is critical for understanding population history but is often confounded by structure and data quality. Here, the authors show that GONE2 and currentNe...

Probabilistic models such as the sequentially Markovian coalescent (SMC) have long provided a powerful framework for population genetic inference, enabling reconstruction of demographic history and an...

Abstract. Differential dispersion between the sexes can impact the colonization process and demographic history of a species. Here, we explored the demogra

Abstract. Rates of molecular evolution are known to vary across species, often deviating from the classical expectation of a strict molecular clock. In man

Environmental DNA (eDNA) metabarcoding is a widely used tool for surveying marine vertebrate biodiversity. To this end, many computational tools have been released and a plethora of bioinformatic app...

Using the Tara Oceans dataset, this study describes global patterns of diatom diversity, abundance and adaptation. The authors identify 25 distinct communities, with the Arctic as a hotspot, and highl...

Nucleotide sequence data are being harnessed to identify species, even in cases in which organisms themselves are neither in hand nor witnessed. Bu...

Protists, defined as unicellular eukaryotes distinct from animals, plants, and fungi, are a polyphyletic group that predominates the eukaryotic tree of life, exhibiting significant phylogenetic divers...

Abstract. Methods for detecting gene flow between populations often rely on asymmetry in the average length of particular genealogical branches, with the A

The cobraa model extends the pairwise sequentially Markovian coalescent to identify structured population history by examination of the model transition matrix. Applied to human polymorphism data, cob...

Phytoplankton and bacteria represent two major pillars of the carbon cycle in marine ecosystems. While their interactions are known to be tightly linked, the specific mechanisms underlying these inter...
