Revisiting an Old Riddle: What Determines Genetic Diversity Levels within Species?

Abstract : Understanding why some species have moregenetic diversity than others is central to the study ofecology and evolution, and carries potentially importantimplications for conservation biology. Yet not only doesthis question remain unresolved, it has largely fallen intodisregard. With the rapid decrease in sequencing costs,we argue that it is time to revive it.
