Humans are and incredibly diverse species that have completely changed the landscape of the earth.  The story of human beings' origin and migration through the world is slowly unraveling.  In this clip the videographers at Quartz put together a visualization of the migration and its diaspora.

Three studies published in the journal Nature answer the question of when humans took the leap forward and found that there was a single exodus more than 50,000 years ago. The researchers analyzed the genomes of 787 people from more than 280 populations that included Mayans, Sherpas, and African pygmies among many other diverse populations. This was unique because most prior research sequenced genomes mainly from Europe and China. Watch this video from Quartz to see how the migration made its way across the globe.
