Evolutionary dynamics of polyploid plants of the genus Cochlearia during past periods of rapid climate change indicate increased rates of speciation and diversification in response to pronounced glacial cycles and cold periods in particular.

Canadian COVID-19 travel restrictions imposed in March 2020 greatly reduced SARS-CoV-2 importations, but were insufficient to prevent new sublineages of similar transmissibility from being introduced and replacing early sublineages.

The evolutionary trajectory of phytophagous weevils reveals how ancient host plant shifts and continental drift influenced the development of diverse insect-plant interactions through time.

The first nuclear genomes of the Equus (Sussemionus) ovodovi enable us to reconstruct the speciation and extinction trajectory of this lineage.

The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO₂ fixation.

The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.

All the characteristic traits of the eukaryotic cell, the basic unit of all macroscopic life, commenced to originate in a prokaryote as means to serve an endosymbiont today known as mitochondria.

Comparative phylogenomic analyses based on a new reference-quality human Ascaris genome assembly reveals a pig/human interbred species complex with implications for Ascaris control worldwide.

A newly developed computational framework provides an overview of the extent, diversity, and relevance of the genes of unknown function in genomes and metagenomes.

Phylogenetic relationships between viral RNA segments are distinct between subtypes and lineages of seasonal human influenza A viruses and implicate RNA-RNA relationships as novel drivers of influenza virus evolution.
