A book that is also an autobiography of a scientist who has done research for more than sixty years, most of them dedicated to rebuild the history of mankind.
It is a peculiar autobiography, where the events of life are a frame and an excuse to find out how to do science, how the knowledge born, what tools we have to find out a past whose traces are mostly gone, but that is remained imprinted in our genes as in our culture and that can be brought to light as long as using the right tools.
