On measures of influence and discordance in phylogenomic analyses Abstract. As models are approximate descriptions of real biological processes, and data are collected often with errors and contamination, sensitivity or r

First up we have Xiyun Jiao and @zihengyang.bsky.social showing the importance of moving beyond model fit testing and embracing sensitivity testing in phylogenetics.

In other words, question your data assumptions and test for model robustness not just adequacy.

Ji, Kapli, Flouri & @zihengyang.bsky.social assess the impact of genotyping errors in phylogenomic data on Bayesian inference of species trees, suggesting that it is better to sequence a few samples at high depths over many samples at low depths.

In the first Plenary speech of #SMBE2025, Ziheng Yang (@zihengyang.bsky.social) taught us quite a few improbable things on gene flow.

We wish you a delicious breakfast for tomorrow, while mulling over these lessons... 😉

Inference of Gene Flow between Species from Genomic Data When the Mode, Direction, and Lineages are Misspecified Abstract. Thanks to genomic data, interspecific gene flow is increasingly recognized as a major evolutionary force that shapes biodiversity. Two models hav
