We now have studies from Kenya, Ethiopia, and Malawi all suggesting the same thing: that African savanna mammals migrated *very little* before the Holocene!

Congrats @barahuber.bsky.social !!!!

Acting CDC director calls for MMR vaccine to be broken up into three shots There's no evidence that breaking up the MMR shot would make the immunization safer or more effective.

“We have 1,544 measles cases this year, 92% in unvaccinated people, and 3 deaths. The problem isn’t the vaccine — it’s that people aren’t getting it. O’Neill hasn’t offered a single scientific rationale for breaking up MMR.”

The Last Glacial Maximum in the Tropics: Human Responses to Global Change, 30–10 ka - Journal of World Prehistory The world at 18,000 BP, published by Gamble and Soffer (The world at 18,000 BP. Vol. 2: low latitude, Unwin Hyman, 1990), represents the first, and so far the only, attempt at characterising and discussing the impact of the Last Glacial Maximum (LGM) on human societies on a global scale. At the time, they highlighted that research and data on the LGM in southern latitudes and the tropics in particular were scant. Since 1990, however, many sites dated to the LGM and located in tropical latitudes have been published. Many paradigms have changed regarding the peopling of the Americas, which allows the archaeology of this continent to be integrated into global scale studies of the LGM. The development of Pleistocene archaeology in tropical contexts, in parallel with methodological advances in cultural, geosciences and palaeoenvironmental studies have strongly reshaped what we know of the antiquity of human occupation in tropical regions and specific human–environment interactions. This article provides for the first time a pan-tropical perspective on the impact of the LGM on human groups living within the tropical latitudes, drawing from case studies in Southeast Asia, Africa and South America, specifically regions which have up until now never been discussed together. To this end, we focus on six different tropical regions between 30 and 10 ka. We present the archaeological and paleoenvironmental data available in these areas, along with proposed relationships for variations in these two records. Finally, we discuss at the regional scale the presence or absence of human changes (site density and techno-cultural change or continuity) before, during and immediately after the LGM.

How did populations in tropical regions cope with the global climatic change around the LGM?

While the tropics are often perceived as having been less impacted by the LGM, we show that -as is often the case - it is more complex than it seems!

1/5 Why do all non-Africans descended from a group that left Africa 50k ago? In @nature.com we model 120k years of human niche dynamics. From 70ka, a big expansion of the human niche in Africa likely equipped later OOA dispersals with a unique ecological flexibilty.

Published today in @nature.com our new study on the drivers of the successful dispersal of modern humans out of Africa! A huge, interdisciplinary team effort long in the making, headed by @elliescerri.bsky.social . Glad to have contributed! www.nature.com/articles/s41... #archaeology #Evolution

Love the paper ;) massive congrats to all!!!

I'm really pleased to be attending the Fyssen Foundation's young researchers awards ceremony in Paris 🤩😍 @fondationfyssen.bsky.social

🔊🔊 Je ne pourrai malheureusement pas participer à la manifestation aujourd'hui, mais je suis de tout cœur avec mes collègues qui vont défendre à Paris l'archéologie française. Cet amendement ne doit pas casser l'un des plus beaux dispositifs d'archéologie préventive au monde !

Congrats !!

Congratulations Michaela ! I look forward to read it 🤩🥰

There is still one day left to apply for our 4 year postdoctoral position here in Vienna...!

La réponse de Harvard aux menaces de l'administration Trump (9 milliards $ en jeu) :

« L’Université ne renoncera ni à son indépendance ni à ses droits constitutionnels.

Ni Harvard ni aucune autre université privée ne peut tolérer d’être mise sous tutelle du gouvernement fédéral »

Simple. Basique.

This is huge !!!! Congratulations to all 🤩😍

Amazing new publication from burial medieval site in Tunisia ! Congrats team !!

Earliest evidence for humans in rainforests New research shows that humans lived in African rainforests 150,000 years ago. This is more than twice as early than previously thought.
