stabilizing selection

stabilizing selection (normalizing selection) Natural selection that acts to maintain the constancy of a species over successive generations. It involves selection against the extremes of the range of phenotypes for a particular characteristic. For example, babies whose birth weight is substantially below or above the average of 3.6 kg historically have a greater mortality than babies of average birth weight (although medical advances have now greatly reduced this pattern of selection in humans). Compare directional selection; disruptive selection.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

stabilizing selection

stabilizing selection(maintenance evolution, normalizing selection) Natural selection that selects against extremes at either end of the range of phenotypes (e.g. in humans babies with low or high birth weights are less likely to survive than those with a birth weight close to 3.4 kg). It occurs in environments that change little from one location to another or over time. Compare directional selection and disruptive selection.

stabilizing selection

stabilizing selection (maintenance evolution, normalizing selection) The stabilizing influence of natural selection in an environment that changes little in space and time. It tends to inhibit evolutionary innovation, and accounts for the fact that many fossil groups changed very little over long periods of time. Compare DIRECTIONAL SELECTION and DISRUPTIVE SELECTION.
