🔦 Feldforschung in Alaska: Der #Geologe Paul Wilcox entdeckte dort in einer schwer zugänglichen Höhle rund 20.000 Jahre alte Ablagerungen. Eine Analyse dieser Proben erlaubte Rückschlüsse über das Ende der letzten #Eiszeit und darüber, wie das Abschmelzen der riesigen Gletscher damals vor sich ging.

Homo juluensis: Scientists discovered a new species of archaic human

A team of paleoanthropologists has introduced Homo juluensis, a newly identified hominin species. This species, whose name translates to “big head,” thrived in eastern Asia between 300,000 and 50,000 years ago, marking a significant addition to the Late Quaternary human lineage...

Homo juluensis: Scientists discovered a new species of archaic human A team of paleoanthropologists, led by Christopher J. Bae from the University of Hawai‘i at Mānoa and Xiujie Wu from the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences, has introduced Homo juluensis, a newly identified hominin species. This species, whose name translates to “big head,” thrived in eastern Asia between 300,000 and 50,000 years ago, marking a significant addition to the Late Quaternary human lineage. For years, paleoanthropologists have grappled with the so-called “muddle in the Middle,” a term describing the confusion surrounding the classification of Middle Pleistocene hominin fossils. Many specimens were grouped into broad categories like “archaic Homo sapiens” or “Middle Pleistocene Homo.” However, Bae and Wu’s work proposes a more nuanced taxonomy, suggesting that eastern Asia hosted at least four distinct hominin species: Homo floresiensis, Homo luzonensis, Homo longi, and the newly named Homo juluensis.

The first paper for our paper club is this recent one from McKay et al., presenting a thorough investigation of the (supposed?) 4.2 ka event. I'd read it when it was published, but just went through again in more detail, and what a good paper. Robust stats (of course, from this group), and they do a really nice job of building the case. I hope the group enjoys it!

NatureThe 4.2 ka event is not remarkable in the context of Holocene climate variability - Nature CommunicationsA study of more than 1000 paleoclimate datasets reveals that the ”4.2 ka event” is not a globally significant climate excursion, unlike the prominent 8.2 ka event. In the Holocene, site-level excursions are common, but global-scale events are rare.

My art in 2023 (8/12)

August: Spring on the mammoth steppe. When the time came to do some art set in the Quaternary, I decided to depict a real life location and how it would have changed in the past few hundred thousand years. This spot is just west of Baden-Baden (which is in the glacier valley to the upper left), on the edge of the Schwartzwald. I also enjoyed depicting an ice age spring. It wasn’t always snow and ice.

A watercolour depicting a flowering steppe landscape in spring on the edge of a snowy mountain range. It is a sunny day, there are many colourful flowers amidst the grasses, and a small river runs meandering through the left side of the image, starting in a valley in the mountains. A raven flies over the entire scene. Below it, there are steppe mammoths bathing in the river. There are seven of them: four adults, all with tusks though one of them has a broken tusk, and three calfs of various sizes. They are large, furry brown elephants, though not as furry as woolly mammoths and with straighter tusks. Two of them are spraying water from their snouts and they are all having a good time. Across the river, a Megaloceros is kneeling to eat some riverbank plants. It is a large deer with extremely impressive antlers. In the lower right corner are two roe deer, quite small compared to the megafauna, keeping an eye on their surroundings. Further in the background we see a herd of steppe bison. They are large, beefy bovids with a big bump on their backs. There are about twenty of them, mostly adults but some smaller young mixed in, and they leave a muddy trampled and grazed trail behind them. Even farther away there are four wolves observing the bison. Behind the wolves the mountains start. Very soon after the landscape's height starts increasing, it becomes snow-covered, and barely any bare rock is visible on the icy mountains.
