Multiple research papers by Arnaiz-Villena et al. propose a "Saharo-Canarian Circle" of prehistoric culture, challenging conventional views of Mediterranean origins. Genetic and archaeological evidence suggests significant cultural and population exchange between North Africa, Iberia, and the Canary Islands, predating established timelines. This interaction, linked to Saharan desertification, influenced the development of languages and writing systems across the Mediterranean, impacting Classical cultures. The research refutes the demic diffusion model from the Middle East, proposing instead an independent and intertwined development in the West.
