Darwinism
The term was coined by Thomas Henry Huxley in April 1860. He used it to describe evolutionary concepts, including similar ideas such as Malthusianism and Spencerism. In the late 19th century, it came to mean the concept that natural selection was the only mechanism of evolution, in contrast to Lamarckism. Around 1900, Gregor Mendel's work was rediscovered. Today, Darwin and Mendel's ideas have been brought together. The term 'Darwinism' has become associated with the modern evolutionary synthesis.
