article_snippet: Study reveals the location of donor and recipient populations analysed .
article_snippet: The Oxford University team first grouped subsets of people in Africa and Europe who were genetically similar.
article_snippet: The Oxford University team were able to separate European genomes into 37 groups.
article_snippet: The Oxford University team then compared the data with the genomes from 2,500 people of mixed ancestry from the Americas.
article_snippet: Overall the group, which also included researchers from University College London and the Universita' del Sacro Cuore of Rome, used DNA sample from 64 different populations. 
article_snippet: Overall the group, which also included researchers from University College London and the Universita' del Sacro Cuore of Rome included people in Barbados, Columbia, the Dominican Republic, Ecuador, Mexico, Puerto Rico and African-Americans in the USA.
article_snippet: The study, led by Oxford University, compared the 'donor' African and European DNA with 'recipient' American populations to see where donor' ancestors came from. '
article_snippet: It was interesting to find so much complexity in the ancestry of American people,’ Professor Cristian Capelli from Oxford University told DailyMail.com.
article_snippet: ’ Professor Cristian Capelli from Oxford University explained how ’ Professor Cristian Capelli from Oxford University team first grouped subsets of people in Africa and Europe who were genetically similar.
article_snippet: Using something known as a 'haplotype-based' DNA technique, researchers were able to separate European genomes into 37 groups.

article_snippet: The proportion of genes from European versus African sources varied greatly from individual to individual within recipient populations.
article_snippet: These results show just how powerful a genetic approach can be when These results comes to uncovering hidden patterns of ancestry,’ added Oxford University's Professor Cristian Capelli.
article_snippet: The Oxford team now hopes to use the same approach to look at other populations with diverse genetic contributions, such as Brazilians.

highlights_snippet: Scientists compared genes of current Africans and Europeans using 4,000 DNA samples from 64 populations .
