Modestly, we decided to review a century's worth of theories of balancing selection :) onlinelibrary.wiley.com/doi/10.1111/...
A century of theories of balancing selection
Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that natur...
