The article discusses the chronology of the human colonization of the Canary Islands, providing new insights into the timing and patterns of early settlement. Using a comprehensive dataset of radiocarbon dates and Bayesian modeling, the study reveals that the Romans likely discovered the islands around the 1st century BCE, while Berber groups from western North Africa first settled one of the islands between the 1st and 3rd centuries CE. The study also shows that Roman and Berber societies did not live simultaneously in the Canary Islands, and that Berber populations rapidly spread throughout the archipelago. The research highlights the importance of applying chronometric hygiene protocols to improve the accuracy of radiocarbon dating and to account for factors such as marine reservoir effects. The findings suggest that the Berber colonization of the Canary Islands occurred between the 1st and 4th centuries CE, with the first human presence on the islands dating back to around 200 BCE. The study also emphasizes the role of agriculture and the introduction of domesticated animals and plants in shaping the island ecosystems. Overall, the research provides a more accurate timeline for the colonization of the Canary Islands and sheds light on the complex interactions between human populations and the environment.The article discusses the chronology of the human colonization of the Canary Islands, providing new insights into the timing and patterns of early settlement.
