The Wallace Line is an imaginary boundary that runs between Australia and the Asian islands and the mainland. This boundary marks the point where there is a difference in species on either side of the line.

What does the Wallace Line tell us about evolution?
To account for the phenomenon, Wallace proposed an imaginary line to divide the region into two parts. The animals found on each side of the line can be shown to have an evolutionary connection to either Asia (to the West of the Wallace line) or Australasia (to the East).
What is Wallace's Line in zoology?
Wallace Line, boundary between the Oriental and Australian faunal regions, proposed by the 19th-century British naturalist Alfred Russel Wallace. ... Although many zoogeographers no longer consider the Wallace Line to be a regional boundary, it does represent an abrupt limit of distribution for many major animal groups.
What did Wallaces line illustrate?
The Wallace Line, which delineates the faunas of Australia and southeast Asia, represents perhaps one of the most distinct biogeographic divisions observed [4], where species west of the line have a predominately Asiatic origin and those to the east show a mixture of Asian and Australian origins.
When did Wallace discover the Wallace Line?
Wallace was fascinated by the biodiversity in Malaysia and Indonesia, wherein 1859 he charted to an exact physical boundary the separation between fauna which is native to Asia and that which is found in Australia. 'The Wallace Line' runs between Bali and Lombok and between Borneo and Sulawesi.
What is Wallace boundary on which basis these are formed?
It was on the basis of such data that Wallace came to the con- clusion that Lombok and Makassar Straits form the boundary between the Oriental and the Australian Regions.
Where is Wallace Line?
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.
Where is the Weber line?
Weber's line A line of supposed 'faunal balance' between the Oriental and the Australasian faunal regions within Wallacea.
What did Darwin and Wallace disagree on?
Darwin argued that human evolution could be explained by natural selection, with sexual selection as a significant supplementary principle. Wallace always had doubts about sexual selection, and ultimately concluded that natural selection alone was insufficient to account for a set of uniquely human characteristics.
How did Wallace help Darwin?
Alfred Russel Wallace was a naturalist who independently proposed the theory of evolution by natural selection. ... This encouraged Darwin to collect his scientific ideas and collaborate with Wallace. They published their scientific ideas jointly in 1858.
What does Wallace Line separate?
The Wallace Line or Wallace's Line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace and named by English biologist Thomas Henry Huxley that separates the biogeographical realms of Asia and Wallacea, a transitional zone between Asia and Australia.
Which island did Wallace find marsupial mammals?
Endemic animals means they are native or restricted to an area. The invisible line is now known as Wallace's Line and the region between it and the island of New Guinea has come to be called Wallacea.
What is Weber's line?
Definition of Weber's line
: a hypothetical boundary lying approximately along the Australo-Papuan Shelf and being sometimes preferred to Wallace's line as the common boundary of the Oriental and Australian biogeographic regions.
Why did Bates go to the Amazon basin?
Henry Walter Bates 1825-1892
He and Alfred Russel Wallace left England in 1842 to explore and collect insects in the Amazon basin in what was to become incredibly valuable explorations and insights into natural history and evolution for the both of them.
Did Darwin steal Wallace's work?
The answer I would give is that no, Darwin didn't steal anything from Wallace. Their theories resembled each other very closely, but they weren't quite identical. ... It inspired Darwin, and they sent letters, or at least something called the Linnean Society published the work in a somewhat under whelming context.
Why is Wallace less famous than Darwin?
Why Evolution is True – Why is Darwin more famous than Wallace? Essentially it was because of the impact of Origin of Species. With their joint paper, Darwin and Wallace can be thought of a co-proposers of evolution by natural selection.
When did Darwin meet Wallace?
This fear was one of the keys that delayed the publication of the theory. It took over 20 years until, in June 1858, an already mature Darwin received a letter from Alfred Russel Wallace (1823-1913).
