The Church Evolution Lab (CEL@NYU) is hiring a postdoc! We have several new projects to study the genomic basis of biodiversity in model clades – especially Hawaiian Drosophila. apply.interfolio.com/179354

Come join our new group, you can study bugs and live in NYC! Feel free to share widely!

Have you ever wondered: just how strong *is* the evidence for Muller's ratchet on mtDNA?

Well, wonder no more!

No molecular evidence for Muller's ratchet in mitochondrial genomes
Muller's ratchet predicts that non-recombining genomes can accumulate deleterious mutations, though molecular evidence for it is rare. Previous studies have tried to detect ratchet-like behavior in mi...

Nguyen et al. used C. elegans as a model to study mitonuclear epistasis, leveraging genetic and phenotypic data to show that mitonuclear epistasis contributed significantly to phenotypic variance across all tested conditions.
