One model for it is W.L. Brown's centrifugal model, in which it occurs outwardly from an epicenter. Early models for it included Ernst Mayr's vicariant model, which Richard Goldschmidt opposed, positing a "bridgeless gap" analogy in which it can only occur via "a fundamental reordering of chromosomal patterns." Mayr later developed the peripatric model for it, which is based on the founder effect as a method of physically separating two populations, just as a mountain range's development or a lake's drying out may cause it. For 10 points, name this splitting of one species into multiple species as a result of geographical separation of populations, the opposite of sympatric speciation.
