| British naturalist Alfred Russel Wallace shares credit for the revolutionary theory of evolution by natural selection with another British naturalist, Charles Darwin. Though the two scientists arrived at their conclusions independently, excerpts of their papers were presented simultaneously at a now famous meeting of the Linnean Society in London in 1858. In addition to his contribution to the theory of natural selection, Wallace is also recognized for developing the concept of Wallace’s line, an invisible border dividing two regions of dissimilar groups of plants and animals. The first of many such biogeographical borders to be identified, Wallace’s line pioneered the field of biogeography. |
