Imagine a mysterious, invisible line that separates two worlds – one with animals found nowhere else on Earth, and the other with a completely different set of species. This line, known as the Wallace Line, is a natural boundary that runs between the islands of Bali and Lombok in Indonesia. But it’s not just a geographic feature; it’s a barrier that has shaped the distribution of life on Earth for millions of years. So, what is this invisible line, and why does it exist? In this video, we’ll explore the science behind the Wallace Line, its historical background, why it happens, and how it divides the animal kingdom.
The Discovery of the Wallace Line
The Wallace Line is named after Alfred Russel Wallace, a British naturalist who, along with Charles Darwin, is credited with developing the theory of evolution by natural selection. Wallace spent years studying the biodiversity of Southeast Asia and its islands, and it was during his travels that he noticed something fascinating.
