African American DNA Research Forum
"The Real Eve"
This is a movie from the Discovery Channel which dramatizes the mutations we see in the mitochondrial DNA maps of how current day populations trace back to Africa.
It is another method of explaining the sometimes confusing scientific concepts of the dna haplogroups that we get in our test results.
I recommend it. It is narrated by Danny Glover and, while the movie is about mitochondrial DNA, the basic concept of how the different peoples of the earth came to be also applies to Y-chromosome DNA.
