Thought art was only for Homo Sapiens? Uranium-thorium dating in Spain tells a different story #lookunderthesurface #howoldisthatpaint ?‍?

Humans arrive in Iberia 45k yrs ago? Caves have ✋ ? 〰️ markings from 65k yrs ago… did Neanderthal fashion inspire art?? ??

This is proof of symbolic thinking and creativity in ?NOT? homo sapiens, were Neanderthals really so different from us?? ?

U-Th dating confirms Spanish cave paintings as oldest in the world, created by Neanderthals in Europe 20KYr before Homo sapiens #ArchaeoArt

65 KYr Neanderthal cave art ends debate that cultural modernity + symbolism seen only in early humans #culturedneanderthals #caughtredhanded

New U-Th dating of crusts on #paleopaintings in 3 Spanish caves gives high accuracy age ranges of cave art, methods for future studies

U-Th dating shows accurate dates without damaging the artwork as it measures associated carbonates, not the art itself #MoversAnd Shakers #Technology

New U-Th dating tech show cave art in Spain 20ka older than first humans in Europe and must be made by Neanderthals. #NeanderthalsUseSymbols

Uranium-Thorium dating uses carbon sample of art layer to find age. Red paint and handprints show deliberate art creation at 3 cave sites.

Neanderthal artists signify long history of symbolic behavior older than 64.8kya, capable of technology once thought unique to H. sapiens.
