Broadcast (2002) Narrated by Danny Glover, “The Real Eve” reveals that our shared genetic heritage links every living person on earth and traces the expansion of modern humans throughout the world. The discovery of the Eve gene stunned the world. It seems we could all be descended from just one female who lived in Africa. In this telling anthropological video, we access the very latest DNA reconstructions, and for the first time, tell conclusively the story of where, when and how the human race came about and then populated the world. The real Eve refers to Mitochondrial Eve, a name used for the most recent common ancestor of all humans in the matrilineal (mother to daughter) line of descent. Scientists have traced the human race to one female in Africa several million years ago and traced the migration pattern of her descendants as they spread across the earth.
In the field of human genetics, Mitochondrial Eve refers to the matrilineal “MRCA” (most recent common ancestor). In other words, she was the woman from whom all living humans today descend, on their mother’s side, and through the mothers of those mothers and so on, back until all lines converge on one person. Because all mitochondrial DNA (mtDNA) is generally passed from mother to offspring without recombination, all mitochondrial DNA (mtDNA) in every living person is directly descended from hers by definition. Mitochondrial Eve is the female counterpart of Y chromosomal Adam, the patrilineal most recent common ancestor, although they lived thousands of years apart.

Each ancestor (of people now living) in the line back to the matrilineal MRCA had female contemporaries such as sisters, female cousins, etc. but none of these female contemporaries of the “Mitochondrial Eve” has descendants living now in an unbroken female line. Mitochondrial Eve is generally estimated to have lived around 200,000 years ago, most likely in East Africa, when Homo sapiens sapiens (“anatomically modern humans”) were developing as a population distinct from other human sub species. Mitochondrial Eve lived much earlier than the out of Africa migration that is thought to have occurred between 95,000 to 45,000 CE. The dating for ‘Eve’ was a blow to the multiregional hypothesis, and a boost to the hypothesis that modern humans originated relatively recently in Africa and spread from there, replacing more “archaic” human populations such as Neanderthals. As a result, the latter hypothesis is now the dominant one.
One of the misconceptions of mitochondrial Eve is that since all women alive today descended in a direct unbroken female line from her that she was the only woman alive at the time. Nuclear DNA studies indicate that the size of the ancient human population never dropped below tens of thousands. There may be many other women around at Eve’s time with descendants alive today, but sometime in the past, those lines of descent included at least one male, who do not pass on their mother’s mitochondrial DNA, thereby breaking the line of descent. By contrast, Eve’s lines to each person alive today includes precisely one matrilineal line.
About 80 millennia ago, out of one major exodus by migratory human ancestors from Africa—from Eritrea to Yemen (then to India and Australia, and eventually to Europe)—was the entire non-African world in all its racial and cultural diversity ultimately peopled; and to one prehistoric woman in Africa 150,000 years ago, all the peoples of the world can trace their genetic origin. So argues Stephen Oppenheimer in a groundbreaking volume that has stirred heated controversy among authorities in geology, linguistics, archaeology, and anthropology. Thoroughly researched and meticulously reasoned, with dramatic evidence garnered from recent advances in the field of genetics through DNA analysis, The Real Eve traces the evolution of modern humankind out of a common African ancestry—for again and again, Oppenheimer’s extensive genealogical research, based on our gender-specific so-called Adam and Eve genes, has led him straight back to Africa. His conclusions have placed him in direct opposition to multiregionalists, who maintain that archaic human populations evolved locally, and have unsettled many long-established anthropological assumptions and cultural prejudices to provide a fresh perspective on the nature of the human destiny that all of us on planet Earth share.
