A) G)  cherriei and G. costaricensis will have accumulated the most genetic differences between them relative to the other Geomydoecus species because they share the most recent common ancestor. B) G)  cherriei and G. costaricensis will have accumulated the fewest genetic differences between them relative to the other Geomydoecus species because they share the most recent common ancestor. C) G)  cherriei and G. costaricensis will have the same number of genetic differences as O. cherrieri and O. heterodus because they coevolved together. D) G)  cherriei and G. costaricensis will have the same number of genetic differences from G. chapini because speciation could not occur in the lice without genetic differences.
