  1. African Eve HypothesisLauren Waelder

  2. A rose by any other name… • Mitochondrial Eve Theory • Out-of-Africa Theory • Recent African Origin (RAO) • Among other variations on Theory/Hypothesis/School of Thought

  3. Who is Eve? Eve, quite simply, is the matrilineal MRCA for all currently living humans. This means that Eve is the matrilineal most common recent ancestor of humanity. Her mitochondrial DNA is found in all living humans, having been passed down from mother to offspring.

  4. Where and what is a mitochondrion? • Plural: mitochondria • Organelle found in eukaryotic cells • Generate ATP as a source of chemical energy

  5. Animal Cell

  6. Why African? • The fossil evidence which supports this theory was found in Africa. • Climate in Africa (water, natural resources, warm temperature) yields to a favorable environment for the raising of human life.

  7. Why Eve?

  8. Popular Eve Misconceptions • Eve was not the only living female at that time. • This is a popular misconception, due to the “Eve” nickname. However, the human race would likely have died out if there had only been one female at the time. • Eve is not the complete MRCA. Eve is the matrilineal MCRA through mitochondria. One can only find traces of Eve in one’s own body through one parent, not two.

  9. How do we know about Eve? • Currently living humans bear mDNA similarities. • Fossil evidence in support of the theory, such as the Omo remains and the Homo sapiens idaltu fossils, have been discovered in Ethiopia.

  10. Eve versus what? The African Eve Hypothesis is as opposed to theories that humans have developed that state that humans developed more or less equally all over the earth at about the same time. The hypothesis claims that humans diffused in a diaspora of sorts over the globe, carrying with them their Eve-influenced mDNA.

  11. Eve in the Scientific Community • Cann et. al published a paper in 1987, “Mitochondrial DNA and Human Evolution,” hypothesizing about the Mitochondrial Eve. • Ingman et. al later in 2000 published results in support of the Cann paper, in the paper “Mitochondrial genome variation and the origin of modern humans.”

  12. Eve in Popular Science Newsweek magazine featuring an article about the “real” African Eve.

  13. Eve in Popular Science II • Discovery Channel filmed a documentary in 2002 titled “The Real Eve” and narrated by Danny Glover • Tim Radford in 2001 wrote an article in the science section of The Guardian about a dispute to the theory in “Neanderthal Man Challenges African Eve”

  14. Bibliography • http://www.raceandhistory.com/cgi-bin/forum/webbbs_config.pl/noframes/read/665, “One African ‘Eve’ for All World’s People” • http://en.wikipedia.org/wiki/Mitochondrial_Eve, “Mitochondrial Eve”
