by Charles Hirschman The Wallace Line does not actually exist in reality. It is an imaginary line that intersects the Lombok Strait between the Indonesian islands of Bali and Lombok to the south, and extends north through the Makassar Strait between Kalimantan (Borneo) and Sulawesi.
He was known for a theory later named the Wallace Line, which is an imaginary divider aligned with the channel between Bali and Lombok in Indonesia. The line divides two zoogeographical regions 1. Introduction. The Indonesian island of Bali lies in a critical biogeographic position—on the edge of the Sunda shelf just west of the Lombok strait that demarcates Wallace's Line [1-4].Yet, the numerous studies of the Indo-Australian fauna usually focus on the larger islands of Borneo and Sulawesi [5-8] and data on the fauna of Bali remain surprisingly scarce and scattered. That line between Bali and Lombok was real, and it signified something very profound to Wallace. He put his thoughts to paper again. Wallace pointed out that under the doctrine of special creationAt the same time, Alfred Russel Wallace tromped through rainforests in South America and then the Malay Archipelago collecting myriads of birds, beetles, butterflies, and other animals and plants, and he discovered the "Wallace Line" between Bali and Lombok, which separates the faunas of Asia and Australia.
Between these two regions of opposite gradient is a region in which contour lines trend north-south. In geochemical studies, there are differences in the chemical characters of the Quaternary volcanic rocks of Lombok, Sumbawa and Bali on the one side and Flores on the other side.
Bali is the eastern end of the Powder Blue Tang (Acanthurus leucosternon) range. It seems that the deep and wide Lombok Strait between Bali and Lombok, which draws the Wallace Line between Asia and Australia, didn't only stop terrestrial species from moving east.
