The authors claim, therefore, that the consensus sequence, Eve 1.0, is nearly identical to the original mitochondrial sequence--that of Eve, the first woman and the mother of every person who has ever lived.
Mitochondria (singular: mitochondrion) are small energy-producing organelles found in cells.
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".
Surprisingly, mitochondria have their own DNA molecules, entirely separate from our nuclear DNA.
Most cells contain between 5 copies of the mt DNA molecule, which makes it a lot easier to find and extract than nuclear DNA.
