The invisible history of the human race: how DNA and history shape our identities and our futures

Ideas about what is passed down are passed down. Do not ask what gets passed down ; The history of family history ; The worst idea in history ; The Reich Genealogical Authority

What is passed down? Silence ; Information ; Ideas and feelings ; The small grains of history ; DNA + culture ; Chunks of DNA ; The politics of DNA ; The history of the world

How what is passed down shapes bodies and minds. The past is written on your face : DNA, traits, and what we make of them ; The past may not make you feel better : DNA, history, and health.
