Professor of Genetics at the University of Florence since 1981. He has always dealt with genetic and molecular analysis of the dynamic processes of life (development and maintenance) as well as their mathematical modeling. Currently in retirement, he has not stopped designing and developing his researches while teaching a course in genetics and behavior evolution, on which he is in the process to write a book. The title of his talk will be “From bacteria to humans: evolution of behavior”, in which he will discuss about the transition from the DNA, seen as a determinant of the behaviorial evolution in bacteria, to the epigenetics (so important in plants and in animals) and the use of complex languages and cultures in the case of humans.
