"The Tuareg of the Fezzan region (Libya) are characterized by an extremely high frequency (61%) of haplogroup H1, a mitochondrial DNA (mtDNA) haplogroup that is common in all Western European populations. To define how and when H1 spread from Europe to North Africa up to the Central Sahara, in Fezzan, we investigated the complete mitochondrial genomes of eleven Libyan Tuareg belonging to H1."

"New research that will be presented Monday, 16 Oct., at the Geological Society of America’s GSA Connects 2023 meeting describes how a series of serendipitous environmental factors allowed an ancient Saharan civilization, the Garamantian Empire, to extract groundwater hidden in the subsurface, sustaining the society for nearly a millennia until the water was depleted."

@bibliolater @science @archaeodons Oh great, using a technology renowned for its fallibility for a task that nobody can check its accuracy.

Sounds like a great idea :eyeroll:

"This paper demonstrates that the highly accurate depiction of the Indian Ocean on the Carta marina of Martin Waldseemueller from 1516 is mainly caused by the extremely powerful political and economic interests of the Portuguese Crown and the Upper German-trading companies in the conflict with the Kingdom of Castile over supremacy in the spice trade in India."
