The Surprises of DNA

DNA: the most wondrous "invention" of Nature and evolution, the true mastermind that allows all living things to exist. But upon closer inspection, it's an episode dedicated to the triumph and secrets of Life. DNA is, in fact, the key that will open the doors to our past and allow us to discover much about our behaviors, how to protect ourselves with new treatments and medicines, and even how to unmask a murderer or reconstruct the appearance of deceased living beings. Alberto Angela explains why in some areas of the world, predominantly people with fair skin, or almond-shaped eyes, or slender bodies live, and why, despite all the differences between human beings, it makes no sense to talk about race. And then, diseases, epidemics like the plague, and the exception of individuals with the same DNA: identical twins.
