Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by DNA sequencing technology, allowing scientists to uncover a new version of human history reaching back more than 100,000 years. In this concise narrative he tells us their long-forgotten stories of migration and intersection. Krause and his colleagues discovered that we share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. This retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.
