According to geneticist, Spencer Wells, there really was an Adam and an Eve. They are known in his circles, as Y Chromosome Adam and Mitochondrial Eve .
Evidently every man on earth is descended from a fellow who lived in Africa 60,000 years ago. The reason Spencer Wells and his fellow geneticists know this is because every man passes Y chromosomal DNA from father to son.
Something called Mitochondrial DNA is passed from a mother to her male and female children so the female evolutionary chain can be traced as well. Every human is descended from a woman who also lived in Africa.
I was astounded by this information. A little disappointed that Y Chromosome Adam and Mitochondrial Eve probably weren't a couple but, jeesh, who could complain? At last I had the answer to the question that plagued my Sunday School years: Who did the children of Adam and Eve marry if they were the first humans?
Well there were lots of other people around in those days - well maybe not lots, but enough to provide mates for the first family. But those poor souls, well, their family lines died out over the years. Only Y Chromosome Adam and Mitochondrial Eve's DNA survived.
So if you are living somewhere on planet Earth reading this today, then you are a descendant of Adam and Eve and you are my cousin!
But it's okay. You don't need to send me a wedding invitation.
