Why do males and females often differ in traits?
The expected answer: selection.
But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

I am happy to share my second paper with @samyeaman.bsky.social and collaborators! If you are into hybrid zones and tree genomics, this is for you!

Really excited that our DFG grant on the Speciation Genomics of Eye Size variation in *Heliconius* has been funded :) In the next weeks, I will post an advert for a PhD, but if you know of good students, please suggest they get in touch. Please repost.

Why is sex so common if it's so costly?
Super excited to share our new preprint “Sex decreases the pleiotropic costs of local adaptation”, where we bring a new angle to this age-old evolutionary question. Co-led by Parris Humphrey, in Michael Desai's lab. Short thread here: (1/n)

Exciting news! @wcratcliff.bsky.social and I published an essay last week in @nature.com reviewing the substantial contributions of 'long-term' studies to evolutionary biology

Just extended the deadline to March 21 for this position in the Plant Phylogenomics group at the University of Vienna. It is sort of a "post doc plus" position funded for up to six years.

Please reach out if you want to chat - I'd love to talk to you about it!

Fungal phylogeny highlighting genome size changes

Summary of genome size variation among groups

@tbadet.bsky.social and I have a preprint out on transposon silencing in fungi!

Genome size evolution is fascinating and showcases the dynamic nature of transposon activation.

What we understand less are the dynamics of transposon defense systems encoded by the genomes.

Latitudinal gradients in air density create invisible topography at sea level, affecting animal flight costs Air density affects the costs of animal flight. This is well-established for flight at high altitude. Shepard et al. show that changes in air density cause regional differences in flight costs at sea level due to latitudinal temperature gradients. They discuss the implications for species distributions and for global change.

@currentbiology.bsky.social does it again!

Our environments are considerably more complex than we typically think. Is it really so surprising that there are broad swaths of biology we don't even know about, let alone don't know how to interpret?

We identified protein domains in LUCA (Last Universal Common Ancestor). Their distinctive amino acid usage reveals the order amino acids were added to the genetic code, based mostly on size. Older proteins hint at earlier alternative codes. 1/15 @seekingluca.bsky.social www.pnas.org/doi/10.1073/...
