'''Microevolution''', broadly defined, is the inevitable small-scale changes in [[allele]] frequencies in a population within the same species. Under this broad definition, this change in overall allele frequencies occurs with every birth or death of a member of the species. In other words, some generations of people might be taller than the last or shorter than the last based on the number of individuals who happen to have the "tall" gene. Microevolution does not involve changing from one [[kind]] to another, and it does not create new kinds.

Evolutionists have argued that the distinction between microevolution and [[macroevolution]] is arbitrary because it is the same process.

== Microevolution vs. macroevolution ==
In 2011, Dr. [[Grady S. McMurtry]] declared:
{{cquote|It is a commonly held belief of evolutionists that small changes in genetic materials (mutations) will ultimately produce the presumed large changes necessary for one biological organism to change into a different kind of biological organism which is commonly called [[macroevolution]]. This belief is not valid. Scientifically, a mutation is a copying error of previously existing information contained in the DNA: a mutation is a structural change in the hereditary material which makes the offspring different from its parents.

It is acknowledged that the Laws of Genetics are conservative, they are not “creative.” Genetics only copies or rearranges the previously existing information and passes it on to the next generation. When copying information, you have only two choices; you can only copy it perfectly or imperfectly, you cannot copy something “more perfectly.” Mutations do not build one upon another beneficially. Mutations do not create new organs; they only modify existing organs and structures. Mutations overwhelmingly lose information; they do not gain it; therefore, mutations cause changes which are contrary of evolutionary philosophy.
As a follow on, the addition of excess undirected energy will destroy the previously existing system. Indeed, you will never get an increase in the specifications on the DNA to create new organs without the input from a greater intelligence.
Mutations affect and are affected by many genes and other intergenic information acting in combination with one another. The addition of the accidental duplication of previously existing information is detrimental to any organism.
Mutations do produce “[[microevolution]],” however, this term is far better understood as merely “lateral adaptation,” which is only variation within a kind, a mathematical shifting of gene frequency within a gene pool. The shifting of gene frequencies and a loss of information cannot produce macroevolution.
As Dr. [[Roger Lewin]] commented after the 1980 University of Chicago conference entitled “Macroevolution”:
“The central question of the Chicago conference was whether the mechanisms underlying microevolution can be extrapolated to explain the phenomena of macroevolution. … At the risk of doing violence to the positions of some of the people at the meeting, the answer can be given as a clear, No.” [Emphasis added]

In 1988, the prominent [[Harvard University]] biologist [[Ernst Mayr]] wrote in his essay ''Does Microevolution Explain Macroevolution''?:
{{cquote|Among all the claims made during the [[Modern evolutionary synthesis|evolutionary synthesis]], perhaps the one that found least acceptance was the assertion that all phenomena of macroevolution can be ‘reduced to,' that is, explained by, microevolutionary genetic processes. Not surprisingly, this claim was usually supported by geneticists but was widely rejected by the very biologists who dealt with macroevolution, the morphologists and paleontologists. Many of them insisted that there is more or less complete discontinuity between the processes at the two levels—that what happens at the species level is entirely different from what happens at the level of the higher categories. Now, 50 years later the controversy remains undecided.
...In this respect, indeed, macroevolution as a field of study is completely decoupled from microevolution.<ref>http://bioinfo.med.utoronto.ca/Evolution_by_Accident/Macroevolution.html</ref>}}
