Not quite so new, as claimed, I am afraid. Lithics have been examined before and show considerable ML influence. And usually LBK enclosures indicate conflicts amongst farming communities. Lot's to learn still, about these early farmers...😜
Archaeologists uncover evidence for interaction between the first Neolithic farmers and Mesolithic foragers in Central Europe, indicating a level of technology transfer never-before observed.

Elizabeth I was crowned Queen of England #OnThisDay in AD 1559. Did you know she had her very own court astrologer, who used an obsidian mirror for occult experiments!

The mirror is Aztec in origin, brought to Europe after the Spanish conquest.

Ferdinand Magellan's expedition to circumnavigate the globe first passed through the Strait of Magellan #OnThisDay in AD 1520.
The southernmost archaeological site in the world (an Indigenous hunting camp) is nearby, on the island of Isla Hornos.

The Treaty of Granada was signed #OnThisDay in AD 1491, ultimately leading to the Emirate of Granada, ruled by the Nasrid dynasty, ceding sovereignty to Spain.
Known for the iconic Alhambra, the Nasrids made use of architecture to display their power.
