Description

By mapping a set of crowd-sourced family trees, researchers were able to watch human migrations over the centuries and learn about changes in behavior over time--like changes in the distance traveled to find love. In the pre-industrial era, people tended to marry someone born within 10 km. Now, that number is more like 100 km. Read the related news story: http://scim.ag/2Fe3T0P
