Just so you know "Out of Africa" comes from the 1985 movie. So the theory can not have been around for longer then 25 years. But that is long enough that they theory should be in the texts books.
I am pretty sure your not willing to do the work, research and study to find out.
So why do you even bring it up? We are looking at the J2B3 halpotype or group.
There is a halpogroup for both Eve with the MtDNA & for adam with the Y-DNA.
If you do not know what I mean when I say: "Out of Africa" then lets stop right here. Your going to have to study population genetics before you can have a discussion. Can I suggest the Book: "The Seven Daughters of Eve". That is the book I read and I really enjoyed reading that book. Very interesting. But there are others book on the same subject. That you can get for less then five bucks used.
Here is a good place to start: "One of the most hotly debated issues in paleoanthropology (the study of human origins) focuses on the origins of modern humans, Homo sapiens.9,10,3,6,13,15,14 Roughly 100,000 years ago, the Old World was occupied by a morphologically diverse group of hominids. In Africa and the Middle East there was Homo sapiens; in Asia, Homo erectus; and in Europe, Homo neanderthalensis. However, by 30,000 years ago this taxonomic diversity vanished and humans everywhere had evolved into the anatomically and behaviorally modern form. The nature of this transformation is the focus of great deliberation between two schools of thought: one that stresses multiregional continuity and the other that suggests a single origin for modern humans."
