I applaud Google´s priorities! Rooting for the Dutch team this weekend against Bangladesh!
We show how this production represents a flexible approach to knapping where no single chaine operatoire was followed, but the a repertoire of different moves was recombined as circumstances dictate.
First visit to @naturalis.bsky.social since return of Homo erectus type specimen.
Gave a talk also on behalf of colleague Fulco Scherjon on Agent Based Modelling of Bandkeramik farmer expansion ~7000 years ago Transformations conference organised by @hanshuisman.bsky.social (Thanks!) www.weleer.nl/transformati... 📷 @welmoedo.bsky.social who gives a keynote tomorrow!
The Leiden botanical gardens have updated their #Dutch #Peat #Bog display to be scarily reminiscent of the state of Dutch nature. Lekker gewerkt! @boerburgerbeweging.bsky.social @vvdonline.bsky.social
The past years I attended and presented at a series of excellent conferences organised by @unileiden.bsky.social African Studies Research Master students. This will be the final time as budget cuts mean the end of this globally recognised excellent programme. ascleiden.nl/news/mining-...
Between 50,000 and 20,000 years ago, South African societies radically reorganised their stone tool technology. Does this reflect cognitive evolution, or something else? Our analysis at Umhlatuzana suggests the latter. www.sciencedirect.com/science/arti...
The post-40 ka stone tools really look much more as what you would expect for sapiens. (📷Burhan et al.2025). Looks alone are not sufficient to attribute stone tools to species. So the pre-40 ka could be made by sapiens. But we know for sure that similar tools were made by other species.
Buiten Julianus de afvallige heb ik het niet zo op dat rijk. Maar nu moest ik er door je post toch weer aan denken. En dan specifiek aan bijgevoegd voorwerp in het museum in Xanten. Het was vlak voor sluitingstijd dus ik was zo stom om de reconstructie niet te fotograferen.
Cool exhibition of archaeological discoveries🏺 from 2024 in Nordrhein Westfalen at Xanten museum. Metal detecting appears better organised in Germany compared to NL.
After the British navy combatting scurvy with lime juice, it seems in WWII the British army went one better!
Sleeping on his side may be the least of this guy's problems. Also: AI pictures are just so ugly. Do people actually click on these things?
Why would you name "rock dwellings" (actually 3D-printed concrete blocks) Navajoo and Hoodoo? One a Native American Nation that do not build rock dwellings; the other a set of African American spiritual practices. Why build "rock dwellings" in the flattest country on earth in the first place?
I do wonder which is more effective: Our policy of appeasement? (which does not (or not fully) combat illegal detecting anyway (attached photo of recent example I came across) Vs. a policy that would require perhaps more enforcement, but also makes the enforcint easier, like the Swiss one.
45k people calling on our politicians to pay attention to the biggest issue of our times: Climate change, which gets zero attention in the current Dutch elections. Also my kids' first demonstration.
Metal-detecting deteriorates into grave-robbing. Visited exhibition on identification of victims from the Battle of Arnhem to encounter this case-study. Illegal metal-detectorist robbing a grave caught red-handed. If not caught the grave would have disappeared unseen.
This is a Dutch one of my mom. But unsure if this would be likely to have made it to Polynesia.
We replicated backed segments of the South African Howiesons Poort phase (65.000 - 60.000 years old) and hafted them transversally and diagonally onto identical arrow shafts. Shooting them at the same speed, at the same distance, at the same targets shows transversal arrows penetrate much deeper.
Another weird stone with grid pattern in a Pavement in Mont st Michel.
Very interesting stones in house in Dol-de-Bretagne. Never seen this before and no clue what it is/means. Anyone?
Also, there seems to be a correlation between churches and ostriches here.
I am really enjoying SAFA conference @icarehb.bsky.social in Faro. Here with Dr Reynard presenting work at Strathalan Cave. Now looking forward to my own talk on the Middle to Later Stone Age transition at Umhlatuzana tomorrow morning.
Spoiler alert! Neanderthal tar production made it to the New York Times puzzle app. Impactful research is about reaching society. We can change how people understand the human condition, from puzzle to (hopefully) common knowledge. Today's message: Neanderthals are cool!
Truly nice afternoon in the sun: World Cup qualification Netherlands - Italy. Vd Merwe taking a wicket.
3. Seeing passenger pigeons was strangely emotional. 4. The botanic gardens have a Bezos-plant
I really enjoyed the Palaeoanthropology association conference andere the subsequent SAA conference in Denver. Takeaway 1: I have kever before been so friendlily treated by US customs. 2: The US, or at least Denver have a serious mental health/homelessness/opium crisis
Current political realities (not naming names....) may really make 3 degrees warming the best-case scenario at the moment. So maybe we should move our collections higher still.... To Berlin? Or even to Mars?
