DNA studies map human migrationThe pattern of genetic mutations offers evidence that an ancient band of explorers left what is now Ethiopia and went on to colonize most of the world.
By Karen Kaplan, Los Angeles Times Staff Writer
Scrutinizing the DNA of 938 people from 51 distinct populations around the world, geneticists have created a detailed map of how humans spread from their home base in sub-Saharan Africa to populate the farthest reaches of the globe over the last 100,000 years.
The pattern of genetic mutations, to be published today in the journal Science, offers striking evidence that an ancient band of explorers left what is now Ethiopia and -- along with their descendants -- went on to colonize North Africa, the Middle East, Europe, southern and central Asia, Australia and its surrounding islands, the Americas and East Asia. A second analysis based on some of the same DNA samples corroborated the results.
