For the past 30 years, “whole-genome sequencing” has been a misnomer. Today the T2T Consortium publishes a dozen papers heralding a future of truly complete genomes for humans and nearly any vertebrate 👨‍🔬🐒🐦🐀🦒🐎🫏🐹🐟 (sorry, no salamanders): www.cell.com/consortium/t... 🧵[1/15]

🚨NEW PAPER 🚨 "Deconstructing empirical fitness seascapes across scales of granularity" published in #G3 (@genetics-gsa.bsky.social) 1/2 The fitness landscape has been among the most influential instruments in evolutionary theory for nearly a century. But we often treat them as fixed and static.

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/...

Clever approach from @astavoe.bsky.social for those pesky lines that were integrated with Rol -- edit them back to nonRol! I wonder what else we could build from all the existing integrated arrays. Switch colors?

Just came across this remarkable interview with Marjorie Grene at age 94: www.thebeliever.net/an-interview... Two of my favourite bits, when Grene is asked about Rorty and about Lakatos: Rorty is just witty, but doesn't have a philosophy and Grene is quick to say that she did not kill Lakatos!

Shubin closes with a reminder of the vital importance of shared evolutionary history in basic biomedical research: we’re learning how to cure human disease thanks to work on fruit flies, worms, and even fish

🗞️ New preprint from the lab, led by our postdoc Ana Garoña (not on here) in collab with @andreagiometto.bsky.social: “Experimental evolution of cellular miniaturization reveals a mechanism for cell size evolution”, aka: “honey, we shrank the yeasts!” 🎥 www.biorxiv.org/content/10.6...

! "Moreover, transphyletic transplantation experiments show that the blastopore lip of M. leidyi leads to the generation of a secondary body axis in embryos of the cnidarian Nematostella vectensis."

Why are leaves the shape that they are? What controls intraspecific, genetic variation in leaf shape? New from my lab, in collaboration with many others, led by PhD student Amanda Peake: mapping the leaf shape polymorphism in Ipomoea hederacea.

How do alternative reproductive modes arise? In this @pnas.org paper, we show that hybridogenesis -where a haploid set of chromosomes is transmitted clonally across generations- acted as an intermediate step between sexual and asexual reproduction in stick insects. doi.org/10.1073/pnas...

Our paper unpacking "fitness" is out doi.org/10.1093/gene.... How to define fitness depends on what question you ask. Selection acts on organismal vital rates, longer-term outcomes make sense for genetic lineages, models link them. "Invasion fitness" = speed, but sometimes probability matters more.

doi.orgWhy there are so many definitions of fitness in modelsAbstract. Evolutionary “fitness” is operationalized in many different ways in models. Its role is to quantify that which is favored by natural selection. G
Joanna Masel@joannamasel.bsky.social

Our latest preprint doi.org/10.32942/X2V... explains why fitness can be defined in so many ways, and which version(s) you should use when. Fitness quantifies what natural selection favors. 1/

Put simply: It coordinates action in more varied and context-dependent ways across more complex environments, AND it regulates a more complex internal environment. Highly recommend this chapter from Sterling and Laughlin! link.springer.com/article/10.1...
