Alfred Wallace was a famous biologist and zoogeographer. He is known as the father of biogeography. Alfred Wallace was born in England 1823, and died in 1913. In 1848, he went on an expedition with Henry Walter Bates to the Amazon. Between 1854 and 1862 he conducted research on the Malay archipelago. During the expedition, he noticed striking zoological differences between animal species of Asia and Australia. He created an imaginary line called Wallace's Line to explain these differences. In a striking coincidence, in 1858 Wallace wrote to another British biologist named Charles Robert Darwin about his ideas of evolution. Darwin had come up with the same theory of evolution. In 1858 Wallace’s contribution was entitled “On the tendency of varieties to depart indefinitely from the original type”. His work describes the theory of natural selection.
