@molbioevol.bsky.socialHale, @coxevolab.bsky.social et al. find that male–female expression imbalance on the X chromosome is widespread across phrynosomatid lizards.

@molbioevol.bsky.socialGenerally, introns shorter than ∼30 bp are considered absent from animals. Hadjez et al. show that such ultra-short introns evolved independently at least twice in animals, in two parasitic lineages.
@molbioevol.bsky.social@euantheyoung.bsky.social et al. show that the role of life-history trade-offs in shaping estrogen receptor-positive breast cancer risk in European populations appears, at most, small.
@molbioevol.bsky.socialLaumer, @prashantpsharma.bsky.social et al. examined the incidence of Pax family genes across chelicerate phylogeny and interrogated the expression and function of Pax2 and Pax6 homologs in the daddy-longlegs Phalangium opilio.
@molbioevol.bsky.socialAguado et al. investigate the salivary proline-rich protein gene family across 27 primate species to test whether dietary ecology has shaped the evolution of this locus.
@molbioevol.bsky.socialThe October 2026 issue of MBE has launched - check in throughout the month for your regular dose of discoveries, methods, protocols, and reviews in molecular evolution.
@molbioevol.bsky.socialHeenkenda et al. inferred a population history of the rhesus macaque with substantial structure between Chinese and Indian populations, with a split time of ∼140k generations ago from an ancestral pop. of ∼65k individuals
@microbesinfo.bsky.social@molbioevol.bsky.socialFang et al. propose a model in which extreme ecological transitions can disrupt ancestral mitonuclear coadaptation and promote the emergence of a new coadapted state through systemic nuclear compensation.
@molbioevol.bsky.socialMontoliu-Nerin et al. discover a Mega-NUMT in Drosophila paulistorum genomes and speculate that it is maintained at relatively high prevalence in nature by balancing selection or due to a yet-undetermined function.
@fishka.bioOne gene, reads off two machines, nowhere to see them together. readhit puts .ab1 traces and NGS reads on the same reference in the browser, depth and consensus under them. Files stay with you. Free, no account. Beta.
@molbioevol.bsky.socialKoch et al. offer insights into the evolution of complex gene repertoires in venoms of predatory cone snails, uncovering how neuropeptide genes were recruited >20 times into the venom and neofunctionalized as doppelgänger toxins.

@molbioevol.bsky.socialBodin, Morlon & @bperezlamarque.bsky.social reevaluated evidence for codiversification in mycorrhizal symbioses, finding that closely related plants often interact with closely related fungi, but their phylogenies do not match.
@molbioevol.bsky.social@marzena-marszalek.bsky.social et al. integrate WGS and RNAseq from 282 wild yeast strains, finding robust signals of nonsense-mediated mRNA decay but no clear evidence of transcriptional adaptation.
@molbioevol.bsky.socialLetcher et al. reveal how Mesorhabditis nematodes evolved a new Y chromosome from sexual ancestors in species that transitioned into autopseudogamy - females produce clonal females plus rare males that are needed for fertilization.
