Grant (1986) proposed a three-step process to speciation to explain the adaptive radiation of the group: (i) The ancestral species arrives in the archipelago; (ii) the species spreads to other islands and as a result of this, there will probably be some selection and hence differentiation in size because the islands are different; and (iii) members of the original and derived populations encounter each other, and as a result of competition for food and selection against intermediates ...
