More discussion on that preprint (yes just a preprint and getting Nature commentary!) about when exactly did the #Neanderthal gene flow into modern humans happen. Acc to Iasi et al, from 47 Ka for about 6000 years. Interesting here is the 'introgression deserts' with immediate selection against Nean genes for certain areas.

Researchers now have unlocked the genome of the #Arabica species and traced its origins to a natural mating between two other coffee species an estimated 610,000 to one million years ago in the forests of #Ethiopia. That makes this species older than our own species #HomoSapiens, which arose in #Africa about 300,000 years ago.

Shiyu site in northern China reveals evidence of an advanced material culture 45,000 years ago
A multinational team of researchers has revealed the existence of an advanced material culture at the Shiyu site in Shanxi Province, China, dating back approximately 45,000 years...
Und weil's so spektakulär spannend ist, hier auch noch einmal die Max Planck-Meldung zu den gut 45.000 Jahre alten #HomoSapiens-Funden aus der #Ilsenhöhle in Thüringen - den immerhin bisher frühsten Spuren moderner Menschen in Mittel- und Nordwesteuropa:
Moderner Mensch schon vor 45.000 Jahren im nördlichen Europa
Neue Funde aus Thüringen belegen, dass der moderne Mensch schon deutlich früher als bisher angenommen im nördlichen Europa lebte. Dies müsse zu einem "fundamentalen Umdenken" der Besiedlungsgeschichte führen.
"...while these #viruses mostly don't cause symptoms, when they do, it's generally in the form of painful blisters in the affected area."
When you stigmatize #herpes, you announce your literal ignorance (and perpetuate manufactured fear created by #JohnLeo and #MaureenDowd in #Time#magazine in the 80's).
... It has been argued that plants should also be classified as intelligent based on their ability to sense and model external and internal environments and adjust their morphology, physiology and phenotype accordingly to ensure self-preservation and reproduction.... 🤷♂️
Just over two decades ago, as the new millennium began, it seemed that tracks left by our ancient human ancestors dating back more than about 50,000 years were excessively rare.
"It’s increasingly looking like this may be one of the most hilariously inappropriate applications of AI that we’ve seen yet." I am riveted by the extensive documentation of how ChatGPT-powered Bing is now completely unhinged. @simon has chronicled it beautifully here: https://simonwillison.net/2023/Feb/15/bing/
Just as a teaser: unquestionably, most of the world's endangered species could be rescued if the #HomoSapiens were no longer at the top of the #FoodChain...
No Zeroth Law, and a #Bing-empowered, freed #ChatGPT could quickly arrive at this conclusion...
Oldest ever Homo sapiens footprint is found, pushing the record back by 30,000 years (phys.org)
