Balancing selection alert!! 🧬🧪

New preprint where we try to quantify how likely (or rather, unlikely) it is for balancing selection to maintain stable polymorphism, and how easy (or rather, challenging) it is to identify its signatures in genomes.

How does a “universal” transcription factor evolve to do species-specific jobs?
Our new preprint reveals how divergence in TBP’s domains shapes transcriptional specialization across eukaryotes.

Molecular determinants underlying functional divergence of TBP homologs
The TATA-box binding protein (TBP) is a highly conserved basal transcription factor and a core component of the pre-initiation complex (PIC) for all three eukaryotic RNA polymerases (RNA Pols). Despit...

Congratulations to @nextstrain for this great paper! Studying the evolution of moulting beyond insects has been challenging, and we are starting to see how moulting is both deeply conserved and evolving differently in pancrustacean lineages. #evodevo #arthropodevolution #MolecularEvolution

Graphical summary of the evolutionary model, in 4 rows, A to D. A: left, bell shaped distribution of phenotypic changes; right, observed substitutions between an ancestral sequence and a modern one, using an outgroup. B: 4 fitness landscapes: no selection, alpha=beta=1, uniform distribution; stabilizing selection, alpha=beta≠1, bell shape; directional selection, either alpha>beta, curve skewed right, or alpha<beta, curve skewed left. C: 4 distributions which are the product of the distribution in A and each of the fitness landscapes. Observed subtitutions are mapped onto them, falling outside of the high density area except for the third, i.e. directional selection alpah>beta. D: cartoon likelihood indicating that only the third fitness landscape is supported.

Hello Bsky World! Can somebody explain to me the difference between dN/dS and Ka/Ks?? I see some sources saying they are the same thing, but then I go and see papers where they use *both* terminologies. Does anybody have sources? Help! 🤔

🔍 Measuring how fast expression evolves opens a path to understanding how organisms evolve—not just what evolves.
This is just the beginning: from single genes to networks, expression clocks can help decode the tempo of evolution.
