OTD in 1859, Charles Darwin’s Origin of Species was published. He’d been working on a long treatise titled “Natural Selection,” but learning that Alfred Russel Wallace had developed a similar theory, he shifted toward a shorter “abstract.”

"The discovery pushes the boundaries of our knowledge of just how small and simple cellular life can become, as it evolves even into forms that are barely alive."

Much of the original manuscript was used as scrap paper by Darwin's children. On the back of this painting of a house is an original manuscript page from Origin!

Darwin's evolutionary (and revolutionary) book is published,

"On the Origin of Species by Means of Natural Selection"

It changed our view of life...

"Quantitative geneticists acknowledge residual confounding as an unsolved problem. However, in practice, researchers face incentives to publish their inferences of genetic associations that are vulnerable to confounding."

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵
The missing heritability question is now (mostly) answered

The concept of "fitness" is central to evolutionary biology but it's not entirely worked out. There are multiple definitions, doubts about predictive power, problems with internal consistency. Here's a paper from last year attempting to solve some of these problems. doi.org/10.1093/evol...

Thrilled to finally share the magnum opus of my PhD that focuses on the genetic basis of evolutionary change! Specifically, we know we can map the genetic basis of a trait, but can we tell which genes will underlie the trait shift when it evolves? doi.org/10.1101/2025...
High-resolution mapping of a rapidly evolving complex trait reveals genotype-phenotype stability and an unpredictable genetic architecture of adaptation
The extent to which adaptation can be predicted, particularly for traits with complex genetic bases, is unknown. Here, we leveraged a model complex trait, model species, and high-powered longitudinal ...

About today’s “GenZ protest” in Mexico: foreigners please be aware that this was not rooted in the movement that originated in Nepal, this was a narrative takeover by the Mexican far-right.

Not a protest, not a social movement: a display of the political rot within a deeply disenfranchised society.
