'Migration has shaped our world and will define our future' is the title of a recently published book that uses a number of new tools of research, including genetic tests, to trace the history of the movement of people since the birth of mankind.2 One conclusion the three authors of the book reach is that migration has always brought large rewards not only for those who were directly involved in it, that is, the migrants, it has also benefited the receiving and sending countries. It is, therefore, not surprising that the number of international migrants has doubled in the last quarter century to more than 200 million.
