Stranger! If you, passing, meet me, and desire to speak to me, why should you not speak to me? And why should I not speak to you?If you meet someone that you don't know on the streets, it's reasonable to think of that person as a stranger. But I just read in this month's Geographics that even though he's not someone you know, he's still someone who's related to you!
~To You/Leaves of Grass/Walt Whitman
"Scientists now calculate that all living humans are related to a single woman who lived roughly 150,000 years ago in Africa, a "mitochondrial Eve." She was not the only woman alive at that time, but if geneticists are right, all of humanity is linked to Eve through an unbroken chain of mothers. Mitochondrial Eve was soon joined by "Y chromosome Adam," an analogous father of us all, also from Africa. Increasingly refined DNA studies have confirmed this opening chapter of our story over and over: All the variously shaped and shaded people of Earth trace their ancestry to African hunter-gatherers."The stranger you meet on the train is technically a distant relative with the same great-great-great...grandparents!
The Geographics also has this very interesting thing going, called The Genographic Project. It invites folks to pay USD100+++ to have their DNA samples analysed to see how exactly their ancestors travelled from Africa to Europe, Asia and so on. Yeah, I know my most immediate ancestors look Chinese. But before that, they were Africans. So how did they walk from Africa? What route did they take? Very intriguing indeed...
