Why don’t all animals use tools? Great question. So, we wrote a paper about it. 🐹🛠️🐜📡🐙🧰 If you like archaeology, technology, game theory, cybernetics, behavioral economics, and/or crazy critters great and small, this is the paper for you. www.animalbehaviorandcognition.org/article.php?...

Archaeologists are often the first people to hold artifacts after their makers. In this case, there are around 47,000 years between me and the human beings who expertly carved these tools. Made by Homo sapiens just leaving Africa, the time between us collapses as I hold their technology in my hand.

15,000 years ago, in one of the the earliest settled communities in the world, a child collected fine clay from the slow-moving river by her home. She then committed an act familiar to all inveterate play-doh enthusiasts; rolling and and pinching the squishy clay into tiny round balls.

This gigantic net, made of human hair (!) was used to corral and catch rabbits by the Hokoham people around 1250 AD. At 165 feet long, we have a physical manifestation of advanced materials engineering, technical skill, and countless hours’ craft. And a new meaning to putting yourself in your work.

"Deep in Admiration" was a talk given at the conference Anthropocene: Arts of Living on a Dangerous Planet at UC Santa Cruz in May 2014. The text appears as the foreword to the collection Late in the Day: Poems 2010-2014 (published by PM Press).
"Science describes accurately from outside, poetry describes accurately from inside. Science explicates, poetry implicates. Both celebrate what they describe. We need the languages of both science and poetry to save us from merely stockpiling endless ‘information’ that fails to inform our ignorance or our irresponsibility."

In a paper under review @abigaildesmond.bsky.social and I argue that self-directed tool use should be the most common form of novel (and possibly temporary) tool use, because of the immediacy of the feedback and the stability of the self as an environment. Fingers crossed it survives review! 🧪🪮🐼

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...

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...
Graphical abstract: The chemokine receptor variant CCR5delta32 is linked to HIV-1 resistance and other conditions. Its evolutionary history and allele frequency (10%–16%) in European populations have been extensively debated. We provide a detailed perspective of the evolutionary history of the deletion through time and space. We discovered that the CCR5delta32 allele arose on a pre-existing haplotype consisting of 84 variants. Using this information, we developed a haplotype-aware probabilistic model to screen 934 low-coverage ancient genomes and traced the origin of the CCR5delta32 deletion to at least 6,700 years before the present (BP) in the Western Eurasian Steppe region. Furthermore, we present strong evidence for positive selection acting upon the CCR5delta32 haplotype between 8,000 and 2,000 years BP in Western Eurasia and show that the presence of the haplotype in Latin America can be explained by post-Columbian genetic exchanges. Finally, we point to complex CCR5delta32 genotype-haplotype-phenotype relationships, which demand consideration when targeting the CCR5 receptor for therapeutic strategies.
