The establishment of European colonies across the world had important demographic consequences because it brought together diverse and distant civilizations for the first time. One clear example of this phenomenon is observed in the Canary Islands. The modern Canarian population is mainly the result of the admixture of natives of North African origin and European colonizers. However, additional migratory flows reached the islands due to the importation of enslaved Africans to cultivate sugarcane and the intense commercial contact with the American continent. In this review, we evaluate how the genetic analysis of indigenous, historical and current populations has provided a glimpse into the Canary Islands' complex genetic composition. We show that each island subpopulation's characterization is needed to fully disentangle the demographic history of the Canarian archipelago. Finally, we discuss what research avenues remain to be explored to improve our knowledge of the impact that the European colonization had on its native population.
欧洲在世界各地建立殖民地产生了重要的人口统计学后果，因为它首次将多样且遥远的文明汇聚在一起。这种现象在加那利群岛有一个明显的例子。现代加那利群岛人口主要是北非原住民与欧洲殖民者混合的结果。然而，由于进口非洲奴隶来种植甘蔗以及与美洲大陆的密切商业往来，更多的移民潮抵达了这些岛屿。在这篇综述中，我们评估了对当地、历史和当前人口的基因分析如何让我们得以一窥加那利群岛复杂的基因构成。我们表明，需要对每个岛屿亚群体进行特征描述，才能全面理清加那利群岛的人口历史。最后，我们讨论了仍有待探索的研究途径，以增进我们对欧洲殖民对其原住民人口影响的了解。
