We know that such very distinct peoples in Sarawak alone, as the Ibans (Sea Dayaks), Land Dayaks, Muruts, Punans, Kayans and Kenyahs, pay attention to omen animals and, in most cases, to the same animals. This points to a common origin of the cult, for in some cases there is no specially obvious reason why that particular species of animal should have been selected. In the three last mentioned peoples the names of the omen animals are practically similar, but many of the Iban names are different.
There can be little doubt that this cult is indigenous to Borneo; it is probable that a cult of omen animals formed part of the fundamental religious equipment of the Ibans before they migrated to Borneo, but it is also probable that the Ibans have borrowed somewhat from neighboring indigenous tribes. Much more information must be obtained before a satisfactory history of this cult can be written.
