DNA analysis traced human ancestry back to an African "Eve," setting off debate about how modern humans evolved. While there was general agreement that Homo erectus dispersed from Africa across Asia between 1 and 2 million years ago, what happened next remained a question. The "out-of-Africa" hypothesis contended that modern humans developed in Africa and migrated from there recently, driving H. erectus into extinction. Proponents of a "multiregional" hypothesis held that H. erectus populations evolved into modern humans in many regions, and that these groups later bred with each other and with groups that emigrated from Africa. The Eve study examined mitochondrial DNA (mtDNA), which is passed only by mothers to their offspring. The researchers, Rebecca Cann, Mark Stoneking, and the late Allan Wilson, estimated that the ancestor of all surviving mt DNA types lived between 140,000 and 290,000 years ago. When did the migrations from Africa take place? They dated the oldest cluster of mtDNA types with no modern African representation to between 90,000 and 180,000 years ago. These populations might have left Africa at about that time, but the mtDNA data could not determine exactly when.The Great DNA Hunt

Here's the DNA studies of several 1000 researchers. You can do the reading on your own. But basically humans started in Africa then migrated in groups. One large group went to parts of Asia where it split into two more groups that populated every other land mass in the world:
