I have an MA in archaeology and run a blog called Living in the Longue Durée about ancient history and whatever else. This profile is mostly funny observations about history and science.

De-Extinction: A History
John Hammond: “None of these attractions are ready yet, of course, but the park will open with the basic tour that you’re about to take, and then other rides will come online six to twe…

So I’ve completed my latest project: a run-through of the history of de-extinction, exploring the many methods that have been tried and treating it as a social phenomenon around science rather than just a snazzily marketed science topic. From Nazi cattle to modern questionable corporate claims.
OK, they emailed me and now it’s in five minutes. 🫡
In Jacob job quest news, I had an online interview scheduled today in which I went to the link they sent and nobody showed up to interview the entire time I sat there.
I emailed to ask if I could do it another time. I stayed home for this.
I hope y’all are having less frustrating days.

Thanks for the draft feature, Bluesky, but I can’t use it because it conflicts with my use of this website for dropping poorly conceived stream-of-consciousness posts that marry whatever my current academic hyperfixation is with necrosis-inducing zoomer brainrot energy immediately when I have ideas.

Happy Darwin Day, y’all.
May the Darwin Day Finch come down your chimney with many a gift of adaptive feeding strategies, differential reproductive success, intraspecific sexual selection, and more.
If you haven’t been very fit this year, you’ll get barnacles.

Still excited about Stoat as a rising Discord competitor but I think these fatal flaws will keep our communities from moving there right now:
1. No pinging roles or everyone.
2. Mobile app is reliant on very modern systems with no plans to make it work for older iOS.

What a man-child.
For people outside of paleontology:
This senior paleontologist, who married a 19-year-old, visited a convicted pedophile in 2012 & 2016. Is beefing over a conference argument from 13 years ago, angry because he was banned from a family-friendly event across the Atlantic. The level of petty.

In researching The Course of Empire series, the political dimensions and impacts of the paintings are really interesting, especially as they criticized Jacksonian expansionism.
Here’s (soon-to-be) Supreme Court Justice Levi Woodbury suggesting the US was immune to decline in response.

Do you ever just think you were born in the wrong generation?
Born to be a member of the North African Neolithic Kiffian culture (7700-6200 BC) in the African Humid Period, forced to exist in the age of credit card debt.

Since I posted this I made a Stoat server.
Mostly learning how to use it right now but I set up a little server with channels for history and science discussion, language-learning, news following, and the like. Come pop by if you want.

I’m not personally gonna leave Discord. The communities I’ve built there are too established.
But fellow moderators and I are looking at Stoat to add an alternative platform for accessibility.
Unfortunately seems like their small team is swamped by the sudden amount of traffic.

One thing I’m thinking about with the Artemis missions is how lunar archaeology will be insane.
Aside from UV radiation, preservation conditions are so much better on the Moon in pretty much every way. Anything we leave up there is an incredible informational gift to some very far future.

Oo, yeah, I might also mention now that it’s over and you guys can’t spoil it, but I have a subtle goal each year of not learning who is playing in the Super Bowl until it happens.
This year I managed 50% of that. Unfortunately, Patriots hate was plentiful enough that I knew they would be in it.

Cute lady who works at the local grocery store who recognizes and notices me at this point called me into her checkout line today.
You never quite know what’s going on in someone else’s head.
She has no idea “John Brown’s Body” was blasting in my ears the whole time and I couldn’t hear shit.

Other than Prehistoric Park barely showing the concept, a Carboniferous walk-in aviary-like structure is pretty unexplored in prehistoric-zoo media. I dunno who needs to hear this but if you’re making any media in this niche genre, think about this please.

On a two-word scientific paper, and a fascinating (heated) exchange
I’ve blogged before about the shortest scientific papers. Very short papers (a handful to a few dozen words) are usually amusing, but they’re often not very effective at communication. But I’ve jus…

One things that’s occurred to me is that we have such a strong visual language for what a “robot” looks like in children’s media and animation, etc. with a blocky head, blinking lights, angular humanoid features, etc. 🤖
With how many robots are being developed, how long until that is overwritten?

A few photos from my little walk this morning.
Let these cygnes be positive for you today.
Also I appreciated the trees near the Hippodrome de Longchamp popping back to life for spring with little bunches of leaves.

I imagine Daedalus in Greek mythology being like the ancient version of the artist who makes too much off of commissions to say no but who is really uncomfortable with what he has to make.
“Pasiphae, it’s not another wooden cow, right? O, big maze… thank Poseidon. That’s more fun.”

This morning I had to add a new rule against thirst posts over on r/PrehistoricMemes.
A small group of people have been constantly posting their weird spec-evo dino girls with big boobs.
Guys, boobs are a synapsid thing. You should know this as evolutionary biology enjoyers.
Also what the fuck.

Been writing about and describing the different paintings in Thomas Cole’s 1833-1836 series The Course of Empire.
After looking at them enough, you really get a feeling of the internal geography of their scenes and I can’t help but want to wander them further.
