Turney and Brown

The Neolithic people migrated into Europe as a result of the rising sea level in the early Holocene age.  Farmers in lower sea levels were more vulnerable to the flooding.

It is unclear if there was a causal effect, but at the same time that the Laurentide Ice Sheet collapsed, there was an expansion of Neolithic farmers migrating to Mesolithic hunter-gatherer territory.

Opposing ideas suggest the migration was a result of cultural diffusion, but there is significant evidence that the coastal flooding caused major migration shifts.

Laurentide Ice Sheet = ❌causing the ?to ⬆ ?wide ➡ flooding the Black Sea, robbing early farmers of low level land

Neolithic farmers forced to migrate to Mesolithic hunter-gatherer land putting population pressure on neighboring regions

Holocene flooding gave way to Neolithic period as farming spread across Europe sparking cultural change on regional scale

Formerly fresh water Black Sea is breached by seawater. Ensuing flooding displaces up to 145000 ppl who look to Balkans and beyond

Neolithic transition in Europe (Turney & Brown)

Radiocarbon dating of freshwater molluscs & marine sediments imply that raised sea levels (#RIP #LaurentideIceSheet) flooded the Black Sea.

On pause ⏸ during the flood and ▶️ afterwords was the expansion of Neolothic sites across Europe. Climate change showed little contribution.

Farmers migrated from the flooded Black Sea to recoup fertile land lost. W/o the Holocene?rise, how/when would Europe have learned 2 farm?

Grace Clipson Summary of Hoffmann et al

#TheFinding: U-Th dating in 3 caves in Spain show there was cave ? before modern humans in Europe, which implies Neandertal origin

#TheImplication: Neandertals w/ vivid symbolic behavior (meaningful placement of ✋ stencils) that was well-rooted (Ardales ? over 25 ka)

#TheFuture: 1) Perhaps more Neandertal ? & ancient non-Neandertal symbolic behavior 2) Re-evaluation of transitional tech industries

Leddy, Hoffmann et al. Summary

New evidence implies symbolic behavior of Neandertals in form of cave art, previously attributed only to modern humans.

U-Th dating of overlying carbonate precipitates from 3 sites in ?? place art @ ~65ka minimum… ~20ka before modern humans arrived in Europe.

Location, placement & technique of art implies premeditation and symbolic behavior of Neandertals independent of modern human influence.

 

Hoffman et al. Summary

Scientists determine age of wall ? in Spanish caves. Stone on top of the ? and beneath the ? is used to ascertain age of the ?.

This ? proves Neanderthals could ?? before ?ing in caves, and developed ??‍? abilities w/o humans. #NeanderthalArtIsStillBetterThenPiccasso

O’Connor, Turney and Brown Summary

Laurentide Ice sheet collapse > ❄ global temp & in ? > expansion of Neolithic farming into Mesolithic hunter gatherer territory

Farmers like lowland, Black Sea flooded by Mediterranean, farmers migrated across continent to find more stable settlements with arable land

Flooding during Holocene drove migration of farming populations, led to continental establishment of farming and onset of Neolithic period.
