Family Secrets

Remember reading the Old Testament and seeing the list of “begats” that seemed to last forever?  This book examines human history as recorded in our DNA.  It’s full of fascinating lore: recently geneticists and statisticians have proved that African countries where the slave trade was rampant  have not only a much higher sense of distrust toward friends and strangers, but also have much poorer economies today over a hundred fifty years later.

And Genghis Khan really did father thousands of children, yet at the same time he lived up to his name as the Destroyer. During the two centuries of the Mongol raids that he initiated, 40 million people died. So many that much of the inhabited earth became reforested. This was the only time in recorded history that the CO2 in the atmosphere actually dropped enough to measure.

Genghis Khan also lives on for his particular Y chromosome. Not only did he pass this on to countless sons, but he and his armies killed so many men with different Y chromosomes that his became the predominant one in many parts of Asia.
