...mitochondrial DNA (mtDNA), is passed down intact from mother to child. Similarly, most of the Y chromosome, which determines maleness, travels intact from father to son. [p.62]
So what is the significance of mtDNA and the Y chromosomes? The article went on to explain:
...by comparing the mtDNA and Y chromosomes of people from various populations, geneticists can get a rough idea of where and when those people parted ways in the great migrations around the planet... 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 the 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. [p.62]
Surprised with this conclusion made by geneticists? Muslims shouldn't be. Here's one of the reasons why:
O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise each other). Verily the most honoured of you in the sight of God is (he who is) the most righteous of you. And God has full knowledge and is well-acquainted (with all things). [Al-Hujurat (49): 13]
