Claims for a Triassic-aged crown lizard merit detailed reanalysis, the results of which find that Cryptovaranoides is not only not a lizard, but is a more distantly related diapsid reptile.

Up-to-date computational pipeline characterizes G-protein-coupled receptor (GPCR) repertoires in the closest relatives of metazoans, providing a framework to investigate the evolutionary origins and ancestral functions of key metazoan signaling pathways.

A genomic analysis shows that the evolution of genome size and gene content among fungal pathogens in the class Sordariomycetes varies depending on their interactions with hosts and vectors.

The zebrafish brain combines a conserved heterogeneity of immune cells with a unique dendritic cell-like population.

Shark dentition is a complex and hyper-diverse trait integrating multiple spatial levels, with mid-scale features being most crucial for functional adaptation, revealing evolutionary patterns that offer insights into distinct ecological strategies.

An evolutionary perspective on immune priming across plants and invertebrates highlights the roles of microbiomes and epigenetic regulation in shaping innate immune memory with promising applications in agriculture and aquaculture.

Amino acids that were abundant since the prebiotic era are enriched in protein binding sites of the most ancient coenzymes, supporting the plausibility of an early coenzyme–peptide world.

The Major Histocompatibility Complex region evolves via gene birth-and-death, resulting in short-lived genes, rapidly expanding gene subfamilies, and many gene fragments.

A comparative analysis of genome-wide seasonal gene expression dynamics across four forest tree species revealed that a shared 'molecular calendar' emerges in winter, constraining gene expression evolution and potentially limiting temporal niche partitioning and species divergence in seasonal environments.

HoxB-dependent anterior–posterior patterning and the evolutionary origin of pectoral fins.
