Mitochondrial dna dating
Although the RAO model has a number of significant technical problems and makes some assumptions that conflict with a biblical perspective, it contains several interesting tenets: 1) there was a single dispersal of mankind with three main mitochondrial lineages interspersed within clans; 2) the dispersion was centered in the Middle East in the recent past; 3) the dispersion was essentially tribal in nature, with small groups pushing into previously uninhabited territory; and 4) genetic evidence indicates that male lineages are much more geographically specific than female lineages, with female migration rates up to eight times greater than males.
This latter tenet is an expression of the Babel account in Genesis, where the initial, well-mixed population split up and migrated according to paternal lineage.
And because the mitochondrial genome is subject to high mutation rates, the lack of significant worldwide variation is evidence for a young mitochondrial genome.
Obviously, each set will be as small as or smaller than the previous set.
Eventually the set will contain only one woman, who is known as "mitochondrial Eve".
DNA molecules consists of a long strand of base molecules arranged in the form of a double helix.
The bases are adenine, guanine, cytosine, and thymine, often abbreviated as A, G, C, and T.
On average, human mitochondrial DNA differs from the original Eve consensus sequence by only 21.6 nucleotides (a nucleotide is a "letter" in the DNA alphabet).
