<hw>Dar*win"i*an</hw> <tt>(?)</tt>, <tt>a.</tt> <ety>[From the name of Charles <ets>Darwin</ets>, an English scientist.]</ety> <def>Pertaining to Darwin; <as>as, the <ex>Darwinian</ex> theory, a theory of the manner and cause of the supposed development of living things from certain original forms or elements</as>.</def>

<note>&hand; This theory was put forth by Darwin in 1859 in a work entitled "The Origin of species by Means of Natural Selection." The author argues that, in the struggle for existence, those plants and creatures best fitted to the requirements of the situation in which they are placed are the ones that will live; in other words, that Nature selects those which are survive. This is the theory of <i>natural selection</i> or the <i>survival of the fillest</i>. He also argues that natural selection is capable of modifying and producing organisms fit for their circumstances. See <cref>Development theory</cref>, under <er>Development</er>.</note>
