Homo ergaster may have been the first human species to leave Africa and fossil remains show this species had expanded its range into southern Eurasia by 1.75 million years ago. Their descendents, Homo erectus, then spread eastward and were established in South East Asia by at least 1.6 million years ago. However, an alternate theory proposes that hominins migrated out of Africa before Homo ergaster evolved, possibly about 2 million years ago, prior to the earliest dates of Homo erectus in Asia.
