Daily Mail: How Europeans colonised the world: Visualisation shows migration and marriage of millions of people over 500 years (and reveals when they stopped marrying their cousins)
* Scientists trawled 86 million profiles from a genealogy website, Geni
* They pieced together migrations, marriages and how long people lived for
* Culture change rather than improvements in transport stopped inbreeding
* Study found that women have migrated more than men over the last 300 years
* Scientists found good genes extend someone's life by an average of five years
* Team created a time-lapse showing these movements into just 30 seconds

Scientists trawled 86 million profiles from a genealogy website to uncover a 'family' of 13 million people predominantly from Europe and North America.
By looking at their genetic data, they were able to create a visualisation of their migrations and lifespans - and reveal exactly when they stopped marrying their cousins.
It was long thought that people in the west stopped marrying close relatives in the 19th century when better transportation allowed them to travel larger distances.
