Bryan Sykes, an Oxford University professor and one of the world’s leading geneticists has worked with a team of scientists in order to find the roots of human species throughout the world.   Comparing mitochondrial mutation rates, he has been able to find a total of thirty-six variations of maternal mDNA within the world’s demographic. Of these 36 variations, Sykes found seven genetic clusters among people from all over Europe. Essentially, each genetic cluster has a root mother from which all the people in that cluster descend. Sykes named these“seven daughters” and explained his theory in the popular book, The Seven Daughters of Eve. Ranging from 10,000 to 45,000 years old, these seven women became the common ancestor of all modern-day Europeans. These variations in maternal mDNA have the potential of being a vital link to what primeval Homo sapien DNA may have looked like.
