Revised evolutionary relationships within Brachycera and the early origin of bicoid in flies
Mulhair et al. uncover a functional bicoid in non-cyclorrhaphan flies, pushing the
gene's origin back by ∼20 million years. Reassessing the Diptera phylogeny using the
largest dataset to date permits ...

We find the fly development gene bicoid is much older than previously thought (~20 million yrs older!) 🪰🧬
To pinpoint its origins we tackled the Diptera phylogeny, providing some resolution (many open questions remain).

On the event of James Watson's death, I highly recommend this 2023 commentary from @matthewcobb.bsky.social and Nathaniel Comfort with crucial new insights into the discovery of the double helix. (And also check out Cobb's brand new biography of Francis Crick) www.nature.com/articles/d41...
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

50 years ago, King & Wilson published a foundational paper that underlies the cis-regulatory paradigm (CRP) of #DevoEvo #EvoDevo, i.e., that *almost* all morphological evolution is driven by mutations in regulatory elements, rather than proteins, and it all arose from simple misunderstanding 🧪 🧵

New preprint! We unexpectedly discovered that some Caenorhabditis species delete parts of their somatic genome early in development, which fragments their chromosomes and eliminates key germline genes. Multiple lines of evidence suggest this bizarre process was present in the ancestors of C. elegans
