===Origin=== The term ''microevolution'' was first used by [[botanist]] [[Robert Greenleaf Leavitt]] in the journal ''Botanical Gazette'' in 1909, addressing what he called the "mystery" of how formlessness gives rise to form.<ref>{{cite journal |last1=Leavitt |first1=Robert Greenleaf |title=A Vegetative Mutant, and the Principle of Homoeosis in Plants |journal=Botanical Gazette |date=1909 |volume=47 |issue=1 |pages=30–68 |doi=10.1086/329802 |jstor=2466778 |s2cid=84038011 |doi-access=free }}</ref> :''..The production of form from formlessness in the egg-derived individual, the multiplication of parts and the orderly creation of diversity among them, in an actual evolution, of which anyone may ascertain the facts, but of which no one has dissipated the mystery in any significant measure. This '''microevolution''' forms an integral part of the grand evolution problem and lies at the base of it, so that we shall have to understand the minor process before we can thoroughly comprehend the more general one...'' However, Leavitt was using the term to describe what we would now call [[developmental biology]]; it was not until Russian Entomologist [[Yuri Filipchenko]] used the terms "macroevolution" and "microevolution" in 1927 in his German language work, ''Variabilität und Variation'', that it attained its modern usage. The term was later brought into the English-speaking world by Filipchenko's student [[Theodosius Dobzhansky]] in his book [[Genetics and the Origin of Species]] (1937).<ref name="talkorigins"/>
