Founder populations are of special interest to both evolutionary and conservation biologists, but the detection of genetic signals of selection in these populations is challenging due to their demographic history. Geographically separated founder populations likely subjected to similar selection pressures provide an ideal but rare opportunity to overcome these challenges.
