About four years ago, three skeletons were found during a construction project on the Caribbean island of St. Martin. According to reports, the skeletons were of two male and one female. The three individuals were believed to have been slaves during the 17th century when the region was ruled by the Dutch and French.

Now, researchers have examined the bones using a new genetic technique. According to the researchers, the study of bones could provide information about the slaves' ethnicity.

The researchers studied the bones to figure out where exactly in Africa the slaves came from. The remains were unearthed from the island of Saint Martin in 2010. The slaves had died about three centuries ago, the researchers said. The study was conducted by researchers from the University of Copenhagen and Stanford University School of Medicine. During the study, the researchers analyzed teeth of the skeletons and also extracted DNA for further study.

As per the researchers, genetic data of the three slaves too was decayed for traditional analysis, but they still know a method that can help in locating the native lands of the three slaves. Carlos Bustamante, a geneticist from Stanford University, said that in the middle passage, Barbarism had brought a number of Africans. The new remains could help the researchers to know about the slaves and their descendants in modern world.

According to the researchers, the study used human RNA to attract DNA segments and complete them despite their damaged state. As per historians, the slave from Africa trade thrived when farms across the southern United States demanded for huge amount of labor. The need led to the largest forced human migration in history. According to the reports, more than 12 million people were forced to leave their homelands.

The three individuals, whose skeletons have been found, were taken from their homelands when they were between the ages of 25 and 40.
