What is the Wallace Line?
Zoogeographical divisions demarcate the Middle East Ocean from Australia. Starting from Bali and Lombok on the east of Java, north through Kaliman State and Sulawesi and south of the Philippines to the Pacific Ocean. This line was proposed by British naturalist Wallace, hence the name. [1]

- In 1857, the ornithologist Sklater divided the world into six bird regions based on the differences in birds around the world. This is the predecessor of the current geographical division of animals in the world. In 1876, the well-known British naturalist evolutionist Taylor Wallace and Darwin both affirmed the correctness of the division of the six regions, and proposed some modifications to form the six major animal geographical divisions.
- Because these six major animal geographical divisions are formed on the basis of ornithological research, they are slightly different from other animal groups. For other animal groups, although there are some differences, it is also applicable to other vertebrates, especially terrestrial vertebrates, but the distribution status of these different groups of vertebrates will have some characteristics. For example, the mammals of the Oriental and Australian New Territories are very different. Although the differences between birds are large, they still have a certain common type. When it comes to the distribution of insects, they are often merged into the Indo-Australian boundary.
