In the past quarter century, the world’s migration rate has doubled. Today, 232 million migrants live abroad, and 90 million more are currently packing their bags.
There were no borders when our ancestors walked out of Africa.
We all come from Africa, where 100,000 years ago a woman called Eve lived on what is now Lake Turkana in Kenya. Her DNA can be found in all of ours, spread across the world during humanity’s first exodus: uncertain and barefoot, we wandered northeast across the Middle East, lost each other splitting west to Europe and east over Asia and the Bering Strait, before heading south for millennia through the Americas. Our walk to populate the world took 3,500 generations to complete.
