One of the main differences between skin rashes and hives is the way that they appear on the skin. The raised, red bumps that are hives are eruptions on the surface of the skin. Rashes are a skin discoloration and will only appear slightly raised from the skinâs surface.
Alfred Russel Wallace, codeveloper of the theory of evolution. The image is modified from http://www.prs.k12.nj.us/schools/phs/science_Dept/APBio/Natural_Selection.html. In 1858, Charles Darwin received a letter from Wallace, in which Darwin's as-yet-unpublished theory of evolution and adaptation was precisely detailed.
Darwin and Wallace presented their accounts of evolution at the same meeting. Darwin finally went public with his groundbreaking theory of evolution by natural selection, while making sure that Wallace received some credit. Darwin's ideas were presented to Britain's leading Natural History body, the Linnean Society.
