Good news! Our paper (with @aabiddanda.github.io @sarahaj34.bsky.social @codushlaine.bsky.social and Priya Moorjani) is now officially online! www.science.org/doi/10.1126/...

Recovering signatures of archaic hominin introgression using ancestral recombination graphsAdmixture between modern humans and extinct hominins has shaped the genomes of present-day individuals, but reconstructing this history has been constrained by the scarcity of archaic samples and unad...www.science.orgYulin Zhang

Have you ever wondered how many archaic populations contributed DNA to modern humans? We know about Neanderthals and Denisovans, but the fossil and genetic evidence suggests a much more complex history! www.biorxiv.org/content/10.6...

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNASIn avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...www.pnas.org

Why do sex chromosomes stop recombining? New models show even weak sexual antagonism can strongly drive recombination suppression, with mating systems shaping the outcome. By @ewanflintham.bsky.social and @charlesmullon.bsky.social doi.org/10.1093/evle...

Sexual antagonism, mating systems, and recombination suppression on sex chromosomesAbstract. The suppression of recombination between sex chromosomes is a widespread feature of genetic sex determination systems. Competing explanations fordoi.org

Thrilled that our new review article on animal hybridization is now up on EcoEvoRxiv! 🎉 Working on this review with @mollyschumer.bsky.social was a blast, and it was such a wonderful opportunity to catch up on all the amazing work in animal hybridization over the last few years!

Molly Schumer

Excited to share this new pre-print from the fantastic @kelsiehunnicutt.bsky.social! Kelsie put together a thoughtful and thorough review on hybridization in animal evolution: ecoevorxiv.org/repository/v.... She tracks notable shifts in perspectives on the study of hybridization through time.

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 pathwaysAuthor 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...journals.plos.org

I am SO THRILLED to share our first fully-lab lab paper!!!!!! Led by @hybridzones.bsky.social & @hagarsoliman.bsky.social, w/ a major assist from @pfschwarz.bsky.social!!!!!!!!!!!!! Read more below, if you're curious (you should be- it's AWESOME!!!!!!!) link: www.sciencedirect.com/science/arti...

Introgression and parental conflict shape repeated occurrences of postzygotic isolation in MimulusPostzygotic reproductive isolation is often thought to accumulate as a byproduct of neutral divergence. Yet it frequently evolves rapidly, in line wit…www.sciencedirect.com
