→Development of life: Objection and creationist use
Although it has been criticised on a number of grounds<ref>Laurence Moran on Talk.Origins criticises the definition for excluding prokaryotes, protozoa, and fungi, and for specifying ''gradual'' changes, and other reasons.</ref>, this is the main concept behind the definition provided by the Oxford Concise Science Dictionary: "The gradual process by which the present diversity of plant and animal life arose from the earliest and most primitive organisms, which is believed to have been continuing for the past 3000 million years".<ref name="TO" />

In an attempt to clearly and concisely clarify which definition they are using, creationists sometimes refer to this defintion with terms such as "goo-to-you" evolution<ref>For example, [http://www.creationontheweb.com/content/view/2610 15 ways to refute materialistic bigotry], by Jonathan Sarfati.</ref>, "molecules-to-man" evolution,<ref>For example, [http://www.creationontheweb.com/content/view/403/ Speedy species surprise], by David Catchpoole and Carl Wieland, ''Creation'' vol. 23 No. 2, p. 13.</ref> or "fish-to-philosopher" evolution<ref>For example, footnote 1 in [http://www.creationontheweb.com/content/view/281 Professing creation], by Carl Wieland and Jonathan Sarfati, ''Creation'' vol. 22 No. 1, p. 36.</ref>.
It is primarily evolution of this definition that creationists disagree with.

E.O. Wilson defines evolution as "any change in gene frequency in a population." Helena Curtis and N. Sue Barnes define evolution as "any change in the frequency of alleles within a gene pool from one generation to the next"<ref Name="TO" />

Creationists object that this definition is used to demonstrate trivial changes that are then used to claim that the entire development of life definition has been demonstrated.<ref>[http://www.creationontheweb.com/content/view/3262/ Refuting Evolution 2], by Jonathan Sarfati, chapter 3.</ref>
