Really excited to share this new paper with Amanda Agosto-Ramos & @spicybotrytis.bsky.social! We use glucosinolates in the Brassicales as an illustrative model to demonstrate what the improvements in genome quality & phylogenetic coverage are teaching us about the evolution of metabolic innovation.
Phylogenetic and genomic mechanisms shaping glucosinolate innovation
Plants have created an immense diversity of specialized metabolites to optimize fitness within a complex environment. Each plant lineage has created n…

Egregious stuff, even given that the entire area of DTC genetics and embryo screening eugenics is scams and snake oil
If you want to read something completely nuts from the unregulated world of direct to consumer genomics, look no further.

And when I say completely nuts, I’m being restrained and polite. Criminal is another word that springs to mind.

Stellar work from @robbeewedow.bsky.social, Brian Donovan, & company continuing the work on how changing genetics can reduce genetic essentialism in students.

This is the kind of work under attack by the current administration. Several grants on humane genetics literacy were targeted this year

Origins of language, one of humanity’s most distinctive traits, may be best explained as a unique convergence of multiple capacities each with its own evolutionary history, involving intertwined roles of biology & culture. This framing can expand research horizons. A 🧵 on our @science.org paper.🧪1/n

At a certain point all the stuff just becomes a throwaway sentence in an intro paragraph and the details disappear. At best I feel like an LLM will deliver you that intro sentence with a bit less work
November 24, 2025 at 5:20 PM
Well the real thing I feel like it misses is all the extra stuff you stumble across on a big literature dive. The original theory behind an area of work, the start of some proxy measure that eventually just becomes the target, the back and forth and the initial skeptic who becomes a life-long hater

Hilariously I couldn’t get this one to provide real sources for more than 25% of the supposed citations. I toyed with it a bit. I’m sure prompt engineering could help a bit but I can’t see it really giving you real knowledge

you can frame the European-American differences in a lot of ways but 'Europeans are poorer than Americans but also more secure' is probably the fairest one. American life is richer in many, many ways, and also far more dependent on your job *and your family* than European life.

Fell down a literature rabbit hole all day about the debate over protein degree/connectivity and evolutionary rate. Then, for fun, asked an LLM about it to see its answer. Wow, things predictably don't bode well for grad students who rely on those tools to do the reading and thinking for them

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).

This is the kind of thing you would do if you had no idea how to achieve economic growth. It's a stunningly stupid move but only one of many that the government has been making over the last 10 months or so. All those years in opposition and they have no idea what to do while in office. Shameful

I can usually predict people’s conclusions based on familiarity with genetics and proximity to experiment-driven fields

Frankly, I don’t think heritability has done any good for the social sciences, nor can it
November 22, 2025 at 7:51 PM
I don’t know, it’s true that pedigree studies still have issues because observations quantitative genetics is intrinsically limited and heritability just isn’t really actionable or informative especially when poorly estimated
November 22, 2025 at 7:50 PM
Not quite, but behavior genetics became almost singularly focused on twins and heritability because of how the field responded to the criticism of his work. They basically purged the animal researchers who were doing more interesting experimental work
November 22, 2025 at 6:36 PM
I think the better evidence than Markel, is the relatedness disequilibrium regression paper by Young. Twin models overestimating seems to be near incontrovertible by now
November 22, 2025 at 5:53 PM
I think my confusion is that for simple traits you wouldn’t really want or need to use these polygenic quant gen methods so the issue seems moot?
November 22, 2025 at 2:00 PM
I’m not exactly sure what you mean, but I’m getting the sense it is based on a confusion over what “heritable” means in the technical sense. It’s not really about how genetic a trait is.
