Your DNA reveals a stunning reality: humankind is a collection of fortunate survivors from a really violent game of musical chairs. While we think about ourselves as the masters of the world, our genetic history shows we were as soon as a threatened types more precarious than the mountain gorillas we safeguard today. For over a hundred thousand years, the entire human population was lowered to just 1,280 individuals, leaving us with less hereditary variety than a single forest of chimpanzees.
