We are all a complete mixture;yet at the same time,we are all related.Each gene can trace its own journey to a different common ancestor.This is a quite extraordinary legacy that we all have inherited from the people who lived before us.Our genes did not just appear when we were born.They have been carried to us by millions of individual lives over thousands of generations.
