Climate change resulted in a freshwater pulse that caused ? levels to rise a maximum of 1.4m #byebyeland #hellomigration #earlyHolocene
Floods triggered the displacement of coastal peoples, leading to cultural diffusion of ? techniques throughout Europe #modelssupportthis
Precise dating techniques helped determine the timeline of this transitional period. The Black ? was crucial for sampling #continentalshelf

Modern?? may not have been the 1st cave ???. U-Th carbon ? of cave in ?? shows that Neanderthals were the #RealPaleolithicPicassos
The cave ? is > 64.8ka – b4 the ? of modern ?? who @ 1st got credit for creating the symbolic cave ? #FakeNews #BattleOfTheHominin

BIG news for paleoanthropology from three ?? sites thanks to U-Th dating of carbonate crusts surrounding cave art #NeanderthalArt
Reliable samples showed a minimum age of 64.8ka or older for the art at each site, predating modern humans by 20ka! #NeanderthalArt
Deliberately placed hand stencils “constitute symbolic activity by definition.” Goodbye impossible coincidence argument! #NeanderthalArt

New dating techniques indicate that flooding of the Black Sea coincides with climate change at the end of the last ice age. This time period

also had a large expansion of agriculture in Europe. The expansion could be caused by the sea level rise and flooding of the Black Sea area.

These findings have immense cultural and migratory implications of sea level and climate change. #AgricultureCulture #AncientFlood
Laurentide ❄sheet melts in N.⬆ Atlantic = large pulse of glacial freshwater into ocean. Sea level ? by 1.4m & climate change ❄?occurs.

@DLHoffmann shows that U-Th dating of stone under cave ? and CO3 deposits over cave ? provides accurate timeframe for Iberian cave art
U-Th dating shows that cave ? at 3 sites in Iberia are ≥ 64.8 ka. Only Neanderthals occupied the area at the time. #independentevolution
Strategic placement of cave ? indicates use of symbolism. Previous claims that humans were first species to use symbolism = #fakenews
U-Th dating from carbonate crusts in 3 ?? caves ➡evidence of cave art that predates arrival of modern?????♂️in Europe 45-40 Ka. #WhoDidIt?
Art work oldest min age dated to 64.8 Ka ➡ 20 kyr before modern human’s arrival in Europe. ☠ remains confirm that ? was done by Neanderthals
Art work = lines, dots, disks, & hand stencils made w/ red pigment. Shows capabilities of Neanderthals and early forms of symbolic behavior.
New technique shows cave art in ?? is dated back to 64.8 ka. This was before humans were in Europe. Shows Neanderthals created this art.
New technique is U-Th dating. Dating of carbonate crusts from on top or underneath the cave art. Provides reliable age range for the art.
Discovery proves Neanderthals used symbols. Ends scholarly debate. Before, scholars thought humans were first to use symbols #NeanderthalArt
U-Th dating of carbonate precipitates allows for precise dating of Iberian red-paint cave art thought to be from modern humans.
With U-Th dating, art at La Pasiega/Maltravieso/Ardales sites were determined to be 64.8 KYA or older: the findings were deemed consistent.
Red-paint markings required light-source and premeditated thought, and were meaningful symbols of early behavioral modernity.

Carbon dating marine life in Black Sea gave range of flood period. Matched with stagnation in new sites b/w 8350 &8230 kyr. Then a boom.

New models show ~30 years of flood gradually displaced shoreline farmers thru Europe. Event caused regional shift to widespread farm culture
