In this lecture, I present an overview of data sharing dynamics with a focus on Human Evolutionary Anthropology. I will first discuss three different views on Open data: "Share or die", "I just don'care" and "Tension between secrecy and openness". Then, I will talk about the complexity surrounding open data dynamics in a relatively small research field, Human evolutionary Genetic and Genomics. Thereafter, I will show some results of empirical studies on the data sharing behavior in human genetics and other scientific disciplines, and describe two cases of good practice (Forensic Genetics and Paleogenetics). Finally, I will discuss the implications of arguments and evidence shown here for the future initiatives of the Associazione Italiana per la Scienza Aperta
