In a new #Viewpoint we argue that the binary definition of #BiologicalSex based on gamete size is a scientifically robust framework that is entirely compatible with the diversity of sexual phenotypes and human gender identities. onlinelibrary.wiley.com/doi/10.1111/...

Biological Sex Is Binary and Rooted in Anisogamy

Drawing on empirical evidence and evolutionary theory, we argue that biological sex is most coherently defined as a binary classification of reproductive strategies rooted in anisogamy (the productio....

Our new paper is officially out ! 🎉 We found that iridescence tends to converge between sympatric Morpho butterflies! This signal is likely driven by predation pressures, bringing new evidence to the evasive mimicry hypothesis, i.e. the evolution of confusion patterns in hard-to-catch prey!

Why do different butterfly species evolve the same shimmering blue wings? Morpho butterflies repeatedly converge on iridescence in sympatry, suggesting predators can drive the evolution of shared warning signals. doi.org/10.1093/evle... Image credit: Wikimedia

Ever wondered what makes some alleles dominant (A) and others recessive (a) ? In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...

Dominance modifiers at the Arabidopsis self-incompatibility locus retain proto-miRNA features and act through non-canonical pathways

Author summary Many plants avoid self-fertilization through a system of self-incompatibility, which allows them to recognize and reject their own pollen. In plants like those in the Arabidopsis family...

The fruit of a team gathering complementary and unique skills of different people, I love when this happens! And happy about the result :) congrats @omeriltas.bsky.social , @kovacik.bsky.social , L. Salomon, S. Hafidh, M. Certner, P. Talacko & K. Harant! nph.onlinelibrary.wiley.com/doi/10.1111/...

The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella

In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self-fertilization, often resulting in the ‘selfing syndrome’ (e.....
