在16世纪初至19世纪末，估计有1200万非洲人作为跨大西洋奴隶贸易的一部分被运往美洲。1807年英国废除奴隶贸易后，皇家海军在大西洋巡逻，拦截继续活动的贩奴船。在此期间，位于南大西洋中部的圣赫勒拿岛成为“解放”非洲人的补给站。1840年至1867年，约有27，000名非洲人登陆该岛。为了调查它们的起源，我们为从圣赫勒拿岛恢复的20个个体生成了全基因组的古代DNA数据。基因数据表明，他们来自非洲中西部，可能是今天的加蓬和安哥拉地区。这些数据进一步表明，他们不属于单一的人口，证实了历史上关于该岛非洲人社区文化多样性的报告。我们的研究结果揭示了奴隶贸易最后阶段被奴役非洲人的起源，并说明了遗传数据如何用于补充和验证现有的历史资料。
Between the early 16th and late 19th centuries, an estimated 12 million Africans were transported to the Americas as part of the transatlantic slave trade. Following Britain’s abolition of slave trade in 1807, the Royal Navy patrolled the Atlantic and intercepted slave ships that continued to operate. During this period, the island of St Helena in the middle of the South Atlantic served as a depot for “liberated” Africans. Between 1840 and 1867, approximately 27,000 Africans were disembarked on the island. To investigate their origins, we generated genome-wide ancient DNA data for 20 individuals recovered from St Helena. The genetic data indicate that they came from West Central Africa, possibly the area of present-day Gabon and Angola. The data further suggest that they did not belong to a single population, confirming historical reports of cultural heterogeneity among the island’s African community. Our results shed new light on the origins of enslaved Africans during the final stages of the slave trade and illustrate how genetic data can be used to complement and validate existing historical sources.
