Happy to share our new paper OA in Genetics. We show that population genomic methods based on ARGs (ancestral recombination graphs i.e. genetic ancestry along chromosomes) for demography inference can be biased when applied to genomes with wide high-recombining regions. doi.org/10.1093/gene...
High-recombining genomic regions affect demography inference based on ancestral recombination graphs
Abstract. Multiple methods of demography inference are based on the ancestral recombination graph. This powerful approach uses observed mutations to model

Two new Science studies on lizard coloration reveal how a delicate interplay of genetics, environment, and social dynamics can either preserve or erase polymorphic diversity in species.

Throat coloration in common wall lizards (Podarcis muralis). From top to bottom: White morph with the characteristic green and black coloration of the nigriventris syndrome; White morph with the ancestral brown phenotype; yellow and orange morphs from populations where individuals show varying expression of the nigriventris characters.

How does development shape skull evolution? In lizards, neural crest–derived skull bones drive rapid sexually selected shape change within species but show long-term constraint, revealing developmental bias linking micro- and macroevolution. Image Credit: Wikimedia

What looked like a hearing organ on a tiny stinkbug’s leg turned out to be something far stranger: a fungal nursery that mother bugs use to coat their newly laid eggs in protective symbiotic hyphae, shielding their offspring from parasitic wasps, a Science study finds. https://scim.ag/3MXQ4bt

Can we predict gene expression evolution? In flour beetles, transcriptome-wide selection predicts expression change, with indirect selection acting strongest on pleiotropic, network-central genes—linking co-expression architecture to adaptation.
