Modern advances in science allow researchers to explore in detail the data related to the events of the past. In particular, DNA analysis techniques help in investigating the characteristics of slavery and the transatlantic slave trade. Scientists have conducted “the largest DNA study to examine African ancestry in the Americas” (Heidt, 2020). Some of the findings are consistent with the known facts, while others have shed light on the characteristics of slavery and the history of this phenomenon.

The most significant data presented to researchers is the identification of the regions of origin of African Americans. In particular, most of the slaves were grafted into South and North America from Angola and the Democratic Republic of Congo, and the oldest roots are found in the Senegambia region (Heidt, 2020). It is noteworthy that the study also refutes the known data according to which a small number of Africans came from Nigeria to the United States. Closer to the end of the slave trade, Nigerians were sent to the Caribbean, after which they often participated in the secondary trade within the Americas. Authors note that “this intra-American trade enriched the genetic contributions of Nigerians in modern African Americans in the United States” (Heidt, 2020). This information is the most important result of the presented research, as it allows discovering new details of the history of the slave trade. The study also provides new data on social dimensions and regional characteristics of slavery. The findings point to a widespread gender bias among men in the Americas in relation to African women. Additionally, the researchers found different patterns of inter-sex relations in different areas of America. For example, in North America, beliefs of racial purity were maintained and encouraged relationships exclusively between African Americans. In contrast, the practice of racial whitening was widespread in South America, in which European men often married African women. Such findings help explain the patterns of racial mixing in different regions, which is important for defining the ancestry of modern African Americans. Thus, the study allows historians to look more closely at the conditions of the slave trade and establish new facts. Most importantly, the analysis provides information that was not previously available or believed to be false. Historical records are often insufficient to identify the origins of modern African Americans, often resulting in misleading descriptions of this racial group in modern-day South and North Americas. Thus, researchers are gradually acquiring more information for further application in the contemporary context. Reference Heidt, A. (2020).
