At a time when immigration and nationalism are causing a stir, a recent campaign by travel search engine Momondo sends a powerful message: we are not that different after all. 

Momondo carried out DNA analysis of people from around the world to identify their true and complex ethnicity. The majority of participants thought they knew everything about their ancestry, while many had firm opinions about other nationalities. The beautiful campaign video captures the reactions of the group - the shock, the confusion and the surprise. 

So far the video has been watched more than 15 million times across different platforms, and audience reactions have been overwhelmingly positive. While the campaign clearly supports Momondo's marketing efforts and the timing may have been lucky, it's an important reminder that we should all be proud of our roots, but learn to embrace our differences.
