@andrejpaleo.bsky.socialInteresting article on the geophysical and geodynamic constraints of the Early Earth in the Hadean on the origins and persistence of the RNA organisms:
"...frequent global sterilization events persisted up until about 4.4 Ga..."

@andrejpaleo.bsky.socialLooks liek a promissing general approach for the choice of characters (in this application -- the genomic ones). Complexity approach on improving the phylogenetic inference with highlighting highly heterogenous regions of the genome.

@andrejpaleo.bsky.socialJust a reminder, that birds had 1.6 times more history before the K-Pg impact than the duration of the Cenozoic Era.
My bet would be that we are severely underestimating Mesozoic diversity of birds (stem or crown).

@clocksevolution.bsky.social@andrejpaleo.bsky.socialToday I've learned that Douglas Erwin is (classical) palaeontology doomer. Is it that bad in US palaeontology?

@andrejpaleo.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.

🙏 Big thanks to both for the great work!
@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.
@molbioevol.bsky.social@haorancai.bsky.social @kgslab.bsky.social & @evodaveo.bsky.social show that genetic correlations are more environmentally stable when driven by polygenic background correlation across many loci, vs. a few large-effect pleiotropic outliers
@ceramb.bsky.social🌋🔥 I am super proud to announce that my PhD student, @barsadas.bsky.social from @mizpas.bsky.social has been elected as the Student Representative of @eseb.bsky.social (ESEB) for the 2026–2028 term!

Big congrats, Barsa! And good luck!!

@linudz.bsky.socialPSS-defined groups also produced smaller, more strongly enriched candidate-gene sets than comparisons based on phenotypic extremes using CAAStools.
The method is available in the beta R package phyloPSS:
@andrejpaleo.bsky.socialInteresting and openly accessible book on the alternative radiation of intelligent tetrapods and their brains: AKA birds or avian dinosaurs.
Apparently there is everything -- the phylogeny as well as scaling.

@alicanter.bsky.socialYou don't even need a patchy environment for this split. Frequency-dependent feedbacks alone can drive full specialization into "plant" or "animal" strategies.
@theramseylab.bsky.socialHello, #AcademicSky! We are a highly collaborative philosophy group interested in the life sciences—esp. #evobio, #cellbio, #devbio, #PaleoSky, #ethology, #cogsci & #AI. Follow us for research updates & the work catching our eye across #philosophy & science!

@albertchristian.bsky.socialYesterday I gave a seminar at WashU’s Ecology and Evolutionary Biology on our recent study, modeling how infectious diseases are “pushed” vs. “pulled” into communities by travellers. Always enjoyable to talk about research! 😊

@molbioevol.bsky.socialÁlvarez-Carretero et al. reexamine claims that molecular clocks are uninformative for dating animal and placental mammal origins, vindicating deep molecular divergence estimates over literalist fossil-based ones.

@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.
