Happy #DarwinDay! Charles Darwin was born #OTD 1809. During the first two years of his voyage aboard HMS Beagle, he collected a considerable number of fossil mammals from South America. Those discoveries sparked the theory of #evolution https://paleonerdish.wordpress.com/2016/04/06/darwins-fossil-mammals/

Happy #BlackHistoryMonth !

You know the drill by now. I don't like talking about Black history. Americans know Black history. I want to talk about white American history. In other words, racism, and the erasure of both positive achievements of, and injustices suffered by, non-white people. That's what people don't know.

Try this: Ask your white US friends what the statue of liberty celebrates.

Now ask your Black friends. Or French folk of any color.

20 years ago, Peter Bellwood @ArchAnthANU and Jared Diamond proposed that language patterns support archaeological evidence indicating agriculture spread from a few centres by population expansion.

Summer workshop on evolutionary quantitative genetics at Friday Harbor is announced: Felsenstein, Arnold, Carter, Jones, Hohenlohe, Machado, Price, Sztepanacz, Uyeda. Info at https://fhl.uw.edu/courses/course-descriptions/course/evolutionary-quantitative-genetics-workshop-2023/.

I've taught at this workshop several times -- it's a beautiful place and good instructors.

Where else can you learn about independent contrasts directly from Joe Felsenstein while watching for bald eagles and orcas?

Are you working on #epigenomics in wild populations? Consider publishing your work in our special issue in @EvolApp

In this episode of the Epigenetics Podcast, we caught up with Sarah Kinkley from the Max Planck Institute of Molecular Genetics to talk about her work on PHF13 and its role in chromatin and #transcription.

"Loss of epigenetic information can drive aging, restoration can reverse it"

"An international study 13 years in the making demonstrates for the first time that degradation in the way DNA is organized and regulated—known as epigenetics—can drive aging in an organism, independently of changes to the genetic code itself.

The work shows that a breakdown in epigenetic information causes mice to age and that restoring the integrity of the epigenome reverses those signs of aging.

"We believe ours is the first study to show epigenetic change as a primary driver of aging in mammals," said the paper's senior author, David Sinclair, professor of genetics in the Blavatnik Institute at Harvard Medical School and co-director of the Paul F. Glenn Center for Biology of Aging Research."
