  1. Results of the self-assignment test of 1225 Galápagos marine iguana samples using the approach of Rannala and Mountain [48] as implemented in the program GENECLASS2 [47]. Proportion of "correctly" assigned individuals includes individuals that were assigned to their island of origin irrespective of the sampling period (i.e. sampled in 1991/93 or 2004; see Material and Methods for details), whereas the second column gives the proportion of individuals assigned to islands other than the island of origin.
