I am aware of the paper. Perhaps showing that there was introgression _into_ the potato lineage would have been a good first step?

Sorry, it's just the time lag in my responses--I'm not actually trying to be funny!

I was simply confused because the H. elevatus data seem very easily explained by introgression/gene flow/whatever-we-call-it. It is confusing to me that HHS is invoked.

No real idea, though I'd probably say yes as well

Maybe I don't get your definition of "hybrid species"--do you just mean one generated by homoploid hybrid speciation?

If so, I will stick with my original statement

β€œHybrid species”? Does that include humans?

Is it the one where one species contributed ~2% of ancestry?

There do seem to be more F1s in plants, for sure. But as you know that’s quite different than gene flow

No, I don’t think I said that…

(Also, my current guess is that more animal systems have gene flow than plant systems!)

Good question! My go-to guide is this classic from @mollyschumer.bsky.social et al:

Oh, it’s simply that they admittedly don’t test the simpler hypothesis that there is gene flow post speciation

I NEED to tell you the story of Tae Heung β€œWilliam” Kim.

He's a graduate student at Texas A&M where he's working on a vaccine for Lyme disease.

He's a *legal permanent resident* of the United States.

And he's been in ICE detention for 12 days & counting, transferred Tuesday to South Texas.

In #GENETICS, @3rdreviewer.bsky.social‬ and @smishra677.bsky.social‬ show it is possible to estimate recombination solely using the allele frequency spectrum and provide a genealogical interpretation of the results, showing how #MachineLearning can provide insights into biology.

Bloomington goes a year without telling residents it can’t fluoridate drinking water The city where fluoride toothpaste was invented has been unable to reliably add fluoride to its drinking water for yearsβ€”and Bloomington officials never notified the public, even after they decided to...

This story is wild. The water in Bloomington, Indiana hasn't been consistently fluoridated since 2020, but the public wasn't notified. Even the Mayor didn't know. It only became public knowledge when IU chemist Dr. Katherine Edmonds* read a footnote in a report.
