The Wallace Line or Wallace's Line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace that separates the ecozones of Asia and Wallacea, a transitional zone between Asia and Australia. West of the line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origin is present. Wallace noticed this clear division during his travels through the East Indies in the 19th century. The line runs through Indonesia, between Borneo and Sulawesi (Celebes), and through the Lombok Strait between Bali and Lombok. The distance between Bali and Lombok is small, about 35 kilometres (22mi). The distributions of many bird species observe the line, since many birds do not cross even the smallest stretches of open ocean water. Some bats have distributions that cross the line, but other mammals are generally limited to one side or the other; an exception is the crab-eating macaque. Other groups of plants and animals show differing patterns, but the overall pattern is striking and reasonably consistent.
There’s an invisible line between two groups of islands in the Indian Ocean with two totally different animal populations. It took three branches of science to figure out why it exists.

Crossing the Wallace Line - languages, genes and a forgotten history
The Austronesian expansion into Island Southeast Asia and the Pacific was the last and most far-reaching prehistoric human migration. Austronesian languages replaced indigenous languages over nearly half the globe, yet the absolute number of Austronesian colonists was small. Recently, geneticists have identified large geographic disparities in the relative proportions of Asian ancestry across different genetic systems (NRY, mitochondrial DNA, autosomes and X chromosomes) in Austronesian-speaking societies of Island Southeast Asia and the Pacific. Surprisingly, a substantial genetic discontinuity occurs in the middle of a continuous chain of islands that form the southern arc of the Indonesian archipelago, near the geographic center of the Austronesian world. In the absence of geographic ba...

Bill Bailey on Alfred Russel Wallace | Natural History Museum
Comedian Bill Bailey shares his huge admiration for Alfred Russel Wallace who died 100 years ago in 1913. Not only did Wallace co-discover natural selection, the driving force for evolution, he also founded a new field of biology - the study of the geographical distribution of animals.

The Austronesian expansion into Island Southeast Asia and the Pacific was the last and most far-reaching prehistoric human migration. Austronesian languages replaced indigenous languages over nearly half the globe, yet the absolute number of Austronesian colonists was small. Recently, geneticists have identified large geographic disparities in the relative proportions of Asian ancestry across different genetic systems (NRY, mitochondrial DNA, autosomes and X chromosomes) in Austronesian-speaking societies of Island Southeast Asia and the Pacific. Surprisingly, a substantial genetic discontinuity occurs in the middle of a continuous chain of islands that form the southern arc of the Indonesian archipelago, near the geographic center of the Austronesian world. In the absence of geographic barriers to migration, this genetic boundary and swathe of Austronesian language replacement must have emerged from social behavior. Drawing on decades of comparative ethnological research inspired by F.A.E. van Wouden’s structural model of Austronesian social organization, later codified by Claude Lévi-Strauss as "House societies" ("sociétés à maison"), we propose a two-stage ethnographic model in which the appearance of matrilocal ‘‘House societies’’ during the initial phase of the Austronesian expansion, and the subsequent disappearance of ‘House societies’’ in lowland rice-growing regions, accounts for the observed linguistic, genetic and cultural patterns.
