What do you know about Louis Pasteur who developed the first effective rabies vaccine back in 1885? One of the most brilliant minds and scientists of all time, writes Rodney E. Rohde. Pasteur died on this day in 1995, and #WorldRabiesDay is marked on the anniversary. buff.ly/56EB92l

Yunxian 2, is that you?! 💀

First day of my lecture course on the evolution of human technology, and my students just voted to have a laptop-free class. Sometimes, all is right with the world.

Prehistoric stone tools were often hafted, but we only find the lithics not the wood/bone part of tools. So it is not always clear how stones were hafted. We tested two ways of hafting the same type of arrow tip, shooting into ballistics gel. Very mythbusters! www.sciencedirect.com/science/arti...

Super happy to be a panelist at this upcoming ZooMS webinar - join us on June 30 for a fun archaeological AMA!

Delighted to see our paper on the evolutionary history of the CCR5Δ32 deletion published this week in @cellpress.bsky.social. Work led by @ravnkirstine.bsky.social, Leonardo Cobuccio and Rasa Muktupavela, and co-supervised by me and @simorasmu.bsky.social. See 🧵 for main findings...

A fossil Pleistocene-age hominin jawbone discovered in Taiwan has now been identified as belonging to a Denisovan, finds a new study in Science. The results provide direct molecular evidence that Denisovans occupied diverse climates and offer new insights into this hominin lineage. scim.ag/4joSUBh

Laughed out loud reading archaeologists characterized - by a physical anthropologist - as “… the senile playboys of science rooting in the rubbish heaps of antiquity.” Subtitle: If Earnest Hooton is insulting you, you must be cool. From Trigger’s “A History of Archaeological Thought”.

I am very happy to share this piece with you, exploring the link between inventiveness and play in nonhuman animals. It was written with care and a sincere desire to convey what science and philosophy can teach us about this fascinating topic. I hope you enjoy reading it! aeon.co/essays/how-e...

Leslie White (1942) on human tool use. Simply breathtaking.

So pumped to announce this fabulous conspiracy-in-progress 📖

Tools - as manifestations of human strategic thinking - can tell us a lot about the people that made them. My new paper (out today!) offers some interpretive frameworks for ancient bone tool analysis. www.sciencedirect.com/science/arti...

Honored to announce I’m writing a book! We understand the importance of stone tools in the Stone Age. But what about socks? Rope? Water bottles? Boats? How did we go from knocking rocks together to the Saturn V rocket? This work takes a long view perspective on how the things we make, make us.

Does a scientific understanding of our world conflict with the marvelous wonder we experience in it? In a word: No. “The possession of knowledge does not kill the sense of wonder and mystery. There is always more mystery.” - Anaïs Nin

What an astonishing thing a book is. It’s a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you’re inside the mind of another person, maybe somebody dead for thousands of years. CARL SAGAN

Sound on for the Carnyx! This is what Romans would have heard going into battle against the Celts, who fought naked with severed enemy heads hanging from their saddles.

Archaeologists -by definition- only find things that survive. Usually that means durable materials; stone, bone, ceramics, glass and the like. This 3,500-year-old Egyptian axe shows how the stone head -often the only surviving component- once articulated with a wooden haft and leather bindings.

At almost 2,000 years old, this child’s wooden toy sword for ‘playing soldiers’ is a remarkable survival from Roman times! Dimensions: 29 cm (L) x 4.7 cm (W) From Vindolanda, a fort on the Roman Empire’s northern frontier. 📷 by me #RomanFortThursday #Archaeology

Sometimes archaeological sites yield truly exceptional finds. For example, this 3,000-year-old ball of yarn, bobbin, and woven fabric. Made from nettle or flax in the Bronze Age; Must Farm, Cambridgeshire, England.

Very cool. Makes me wonder about the relationship between this and a fractal. “Mathematicians soon realised that they could construct ever-larger infinite sets, creating a hierarchical ladder of sets that is itself infinite…”
