Have you ever wondered: just how strong *is* the evidence for Muller's ratchet on mtDNA? Well, wonder no more! (Project led by Yu Mo, with @smishra677.bsky.social and @yadirapga.bsky.social) "No molecular evidence for Muller's ratchet in mitochondrial genomes" www.biorxiv.org/content/10.6...

New paper led by @yadirapga.bsky.social! Opossums have babies at 6-months of age, but are still highly male-biased in their mutations academic.oup.com/genetics/adv...

New paper led by @glom.bsky.social! "Unprecedented female female bias in the aye-aye, a highly unusual lemur from Madagascar" 1/ journals.plos.org/plosbiology/...

New paper led by @yadirapga.bsky.social! Even though opossums have kids at 0.5 years, they still have typical male-biased mutation (though not quite as high as humans). "Low mutation rate but high male-bias in the germline of a short-lived opossum" www.biorxiv.org/content/10.1...
