Dating reliability criteria met, age of sites consistent. W/ modern human Euro arrival ~45-40k years ago, 20k yr late ➡ must be #NeanderArt
@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.

New models show ~30 years of flood gradually displaced shoreline farmers thru Europe. Event caused regional shift to widespread farm culture
Not all cave ? was made by modern ????. ? technique dated cave ? as far as 64.8 ka ago in ??. Only Neanderthals were there at this time.
U-Th dating involves taking samples from the associated carbonates in cave ?. Scholars now able to get a dependable age range for cave ?.
Similar cave ? elsewhere in ?? may also be of Neanderthal origin. Neanderthals likely used symbolic expression before humans were in ??.

Up to 145,000 Neolithic farmers displaced, move to Mediterranean coast / inland. Radiocarbon dating indicates sudden burst of farming sites.
Sudden migration = population pressure, social turmoil and cultural change, triggers onset of Neolithic in Europe. Lessons for today?
